Description: TITLE POLY(FLUOROALKYL) SUGAR REAGENTS AND THEIR USE FOR SURFACE MODIFICATION TECHNICAL FIELD This invention relates to a novel group of poly(fluoroalkyl) sugar reagents, a method for their use for the modification of the surface of solid or liquid supports, and supports used for application in the separation of biomolecules, enzyme immobilization, heterogeneous diagnostic assays, and biosensors.- BACKGROUND ART Numerous methods have been developed for the immobilization of proteins and other biomolecules onto solid or liquid supports. A description of these methods can be found in general reviews such as that given by Mosbach, 1976, Methods in Enzymology, Vol. 44; Weetall, 1975, Immobilized Enzymes, Antigens, Antibodies, and Peptides; or Kennedy et al., 1983, Solid Phase Biochemistry, Analytical and Synthetic Aspects, Scouten, ed., pp. 253-391. The most commonly used methods are adsorption or covalent binding to the support. Adsorption is the oldest and simplest method for protein immobilization. To effect immobilization, a solution of the protein is contacted with a support material such as alumina, carbon, an ion-exchange resin, cellulose, glass or a ceramic. Although the immobilization procedure may be simple, the interactions involved in the adsorption process are complex and include charge-charge, van der aals and hydrophobic interactions, and hydrogen bonding. The adsorption method has the advantages of low cost, extreme simplicity, mild immobilization conditions and the ability tc regenerate the support. The main limitation of this method is the relatively weak interaction between the protein and the support, which may result in desorption of the protein upon changes in pH and ionic strength. The often undefined nature of these interactions also can limit their use. The most frequently used immobilization technique is the covalent binding of the protein to chemically activated solid supports such as glass, synthetic polymers, and cross-linked polysaccharides. (Generally, this technique results in a protein which is immobilized in a more stable fashion than protein immobilized by adsorption.) An example of this method is the cyanogen bromide activation of polysaccharide supports, e.g., agarose. Although these traditional supports have been used in many applications, they suffer from some limitations. The polysaccharide supports are compressible, which limits their application in column configurations at high flow rates. These supports are also susceptible to icrobial attack. Silica supports are not stable under alkaline conditions. Polymeric supports are also not chemically inert, and usually have a specific gravity close to 1, which results in long settling times in batch operations. Moreover, all of these supports exhibit varying degrees of nonspecific binding of unwanted proteins. The use of solid and liquid fluorocarbon supports overcome many of these limitations. Fluorocarbons are chemically inert and mechanically stable. The high specific gravity of fluorocarbon supports results in rapid settling in batch operations. However, it is difficult to activate fluorocarbon supports for immobilization. Fluorocarbon polymers have been used as supports to which biomolecules have been attached by adsorption [U.S. 3,843,443, issued to Fishman on October 22, 1974; WO 8603-840-A filed by Rijskuniv Groningen; Danielson and Siergiej, Biotechnol. Bioeng. 23, 1913-1917 (1981); Siergeiej, Dissertation Abstracts, Int. B., Volume 44, 153 (1983) ] . Because these methods rely on simple adsorption of the biomolecule-onto the support, the attachment is relatively weak. Consequently, some or all of the immobilized biomolecule is lost during use. In addition, a significant loss of biological activity of the biomolecule results upon adsorption. Busby et al. (U.S. 4,317,879, issued March 2, 1982) disclose the covalent attachment of the enzyme glucose oxidase to a fluorocarbon membrane. The membrane was first etched with a sodium dispersion in naphthalene, followed by paraformaldehyde linking of the enzyme. This method requires severe chemical conditions to activate the fluorocarbon surface for covalent binding to the enzyme. Hato et al., (U.S. 4,619,897, issued October 23, 1986) disclose the immobilization of enzymes onto a fluorine resin membrane which is made hydrophilic on one side by penetration of a perfluoroalkyl surface active agent to a prescribed depth. The asymmetrically functional membrane obtained is then treated with an enzyme and a cross-linking agent such as glutaraldehyde to effect immobilization. In this approach, the fluorocarbon surface is not activated for covalent attachment of the enzyme. Rather, the enzyme is cross- linked within the pores of the wetted membrane. This approach is limited to porous fluorocarbon membranes. The use of perfluorocarbon polymer-based supports for enzyme immobilization and affinity chromatography is described in U.S. 4,885,250 issued December 5, 1989. In this method the biomolecule is first modified by reaction with a perfluoroalkyiating agent such as perfluorooctylpropylisocyanate described in copending Application No. 134,028. Then, the modified protein is adsorbed onto the fluorocarbon support to effect immobilization. This procedure works well for the immobilization of many biomolecules, particularly immunoglobulins. However, substantial loss of biological activity results for some proteins because of the need to use organic solvents (16% v/v) in the perfluoroalkylation reaction, the hydrophobic nature of the fluorocarbon support, and the need for multipoint modification of protein to obtain secure immobilization. Multipoint modification of the biomolecule is required because of the mono(fluoroalkyl) reagents used. In addition, the mono(fluoroalkyl) reagents desorb from the support in the presence of high levels of organic solvents, e.g., about 50% or greater. A revised method for immobilization onto fluorocarbon surfaces or non-fluorocarbons which contain a fluorocarbon interlayer attached to the surface of the core has been described in copending Application No. 413,867. In this revised method, a perfluoroalkylating reagent containing a mono(fluoroalkyl) anchor group, a hydrophilic spacer arm, and a reactive group for covalent coupling to the protein is adsorbed onto the surface of the support. An aqueous solution of the protein is added to effect immobilization. This approach overcomes many of the limitations of the original method. Higher retention of activity, particularly for enzymes, is obtained because totally aqueous solutions of the enzyme are used, and the surface of the support is more hydrophilic. This approach also provides a preactivated support which is more convenient to use. However, the support with the adsorbed reagent is not stable because the reagent is secured by only one fluoroalkyl anchor group. In addition, multipoint attachment of the biomolecule is required for secure immobilization. In copending Application No. 413,867 a method for forming solid supports for size exclusion and ion- exchange separations is described. The support is prepared by forming a fluorocarbon interlayer by attaching a fluorocarbon to the surface of a solid carrier, followed by treatment with a fluorosurfactant. The use of a neutral fluorosurfactant results in a size exclusion support, while a charged fluorosurfactant* provides an ion-exchange support. The stability " of these supports is limited because of the mono(fluoroalkyl) anchor group which adsorbs to the fluorocarbon surface. Giaver, (U.S. Patent 4,619,904, issued October 28, 1986) describes the use of fluorocarbon emulsions in agglutination immunoassays. The emulsions were formed by adding a fluorinated polar molecule such as penta- fluorobenzoyl chloride to a fluorocarbon liquid. The resulting emulsion was contacted with an aqueous solution of the protein. Again, mono(fluoroalkyl) anchor groups were used to immobilize the protein. Lowe et al. in copending Application No. 428,154, describe the attachment of biomolecules to fluorocarbon surfaces by means of a polymer such as poly(vinyl alcohol) , which has been chemically modified to contain . a significant number of perfluoroalkyl groups. Although this approach provides multiple fluoroalkyl anchor groups for secure attachment to the fluorocarbon surface, the number of anchor groups is difficult to control and reproduce. De Miguel et al., Chromatographia, Vol. 24, 849-853, 1987, describe the strong retention of phenyl- D-glucopyranoside, modified with multiple fluorocarbon chains, on fluorocarbon bonded phases under reversed phase conditions. The authors speculate that such strong retention may allow dynamic anchoring of biomolecules. No examples were provided. The compounds described cannot be used for immobilization because they contain no reactive group to couple to the biomolecule. The major difference between the phenyl-D- glucopyranosides of De Miguel et al., and the present invention is that their compounds do not contain a spacer arm and reactive group for covalent binding to the biomolecule. One object of this invention is to provide a superior composition for modifying fluorocarbon surfaces that permit good retention of biomolecules. Another object of this invention is to provide a reagent for facilitating immobilization of biomolecules on a support with retention of biological activity. Yet another object of this invention is to provide a method for forming a solid support using the superior reagents described herein. Still another object of this invention is to provide a process for immobilizing a biomolecule onto a fluorocarbon surface. SUMMARY OF THE TNVENTTON This invention relates to poly(fluoroalkyl) sugar reagents for modification of the surfaces of supports used in immobilizing biomolecules. The poly(fluoroalkyl) sugar reagents claimed in this invention are comprised of a sugar template to which are bonded multiple fluoroalkyl anchor groups and an optional spacer, attached to a reactive group to covalently bind to biomolecules, a charged group to form an ion-exchanger, or a non-ionic group to give a neutral fluorosurfactant. These reagents are adsorbed onto fluorocarbon surfaces to provide supports for such applications as the separation of biomolecules, enzyme immobilization, heterogeneous diagnostic assays, and biosensors. The reagents and supports described herein offer advantages over those of the prior art because the poly(fluoroalkyl) sugar reagents are adsorbed on fluorocarbon support surfaces more strongly than mono(fluoroalkyl) reagents. Examples of novel compositions claimed herein are as follows: (a) a composition of the structure: wherein: o I R is selected from C(CH2)m(CF2) n CF 3 ; m = 1-5; n - 3-20; x = 1-10; and R' is selected from the following structures CHO, H, CONHNH 2 , CH 2 NH 2 , CH 2 NHCOOCH 2 Ph. (b) a composition of the structure; wherein : R is selected from CO (CH2) m (CF2) n C F 3'' x - 1-10; m « 1-5; n ■ 3-20; and R' is CHO, CONHNH 2 , CH 2 NH 2 , CH 2 NHCOOCH 2 Ph. ' (c) a composition of the structure: wherein: R is CO(CH2)m(CF 2 )nCF3; x « 2-10; and R' is selected from CHO, H, CONHNH 2 , CH 2 NH 2 , CH 2 NHCOOCH 2 Ph. (d) a composition of the structure : wherein: R is CO(CH2) m (CF2) n CF 3 ; m » 1-5; " n - 3-20; R 1 is CH 2 OCH 2 PI1, H, phenyl, CH3 or C2H5; and x - 1-20. The invention also concerns: (1) a support containing an attached binder for a biomolecule consisting essentially of: (a) a fluorocarbon surface; and (b) a polyfluoro sugar composition comprised of a sugar template to which are attached multiple fluoroalkyl anchor groups securely attached to the surface of said fluorocarbon interlayer, said sugar template further consisting of a spacer containing a reactive group capable of coupling to a biomolecule. (2) a process for immobilizing a biomolecule on a fluorocarbon surface comprising the steps of: (a) activating the fluorocarbon surface by contacting the fluorocarbon surface with a reactive poly(fluoroalkyl) sugar reagent containing a sugar template to which are attached a plurality of fluoroalkyl anchor groups, an optional spacer and a reactive group by causing the fluorocarbon surface to adsorb the reagent; then (b) adding a solution of a biomolecule to the activated fluorocarbon surface to attach to the sugar reagent to immobilize the biomolecule on the fluorocarbon surface. (3) a process for immobilizing a biomolecule on a fluorocarbon surface comprising the step of: (a) attaching a poly(fluoroalkyl) sugar reagent to a biomolecule to form a conjugate; and then (b) adsorbing the resulting conjugate on a fluorocarbon surface. DESCRIPTION OF INVENTION The poly(fluoroalkyl) sugar reagents claimed in this invention contain a sugar template to which are attached multiple fluoroalkyl anchor groups. The sugar can be a monosaccharide, such as glucose, mannose, galactose, gluconic acid, and glucoheptanoic acid, a disaccharide, such as maltose and lactose, or any polyhydroxy compound with a well-defined number of hydroxyl groups. These structures permit the attachment of multiple fluoroalkyl anchor groups. For example, glucose, gluconic acid and glucoheptanoic acid allow attachment of four, five and six perfluoroalkyl anchor groups, respectively. The glucoheptanoic acid reagent is preferred because the six fluoroalkyl groups provide the most secure attachment of the reagent to the fluorocarbon surface. The sugar reagents may be dissolved in an aqueous or mixed organic solvent (see Example 1) . The sugar reagent group is a moiety containing at one end, a highly fluorinated anchor group, such as perfluorobutyl, perfluorohexyl, or perfluorooctyl, capable of attaching to a fluorocarbon surface and at the other end, a reactive group capable of covalent . coupling to the biomolecule. Examples of reactive groups include: carboxylic acid, amine, acylhydrazide, aldehyde, an active ester such as N-acyloxysuccinimide, acylimidazolide and epoxide. The anchor portion and the reactive group can be separated by a spacer group. Alternatively, reagents with a polyoxyethylene group can be used as neutral surfactants to prepare supports for size exclusion chromatography. Charged groups, such as quaternary ammonium ion and carboxylic acids, are used to prepare ion-exchange supports useful in ion-exchange chromatography and ion-exchange membranes. A general method of forming the solid or liquid support of this invention useful for bioseparations, enzyme immobilization, diagnostic assays, and biosensors, is to first activate the fluorocarbon support by adsorbing the poly(fluoroalkyl) sugar reagent onto the surface. The poly(fluoroalkyl) reagents are adsorbed much more strongly than mono(fluoroalkyl) anchor reagents. The poly(fluoroalkyl) reagents adsorb onto fluorocarbon surfaces in the presence of high concentrations of organic solvents, e.g., acetone, 50 to 90%, while mono(fluoroalkyl) reagents are desorbed from the fluorocarbon surface in the presence of high levels of organic solvent, e.g., acetone, 50% or greater. To effect immobilization, an aqueous solution of the biomolecule is added to the activated fluorocarbon support. A poly(fluoroalkyl) sugar reagent with a poly(oxyethylene) group, e.g., reagent 38, a neutral fluorosurfactant, can be coimmobilized along with the reactive poly(fluoroalkyl) sugar, to minimize nonspecific binding of other proteins and to improve the retention of biological activity of the immobilizing reagent. The surfactant also renders the surface more hydrophilic which improves the wettability of the support. Alternatively, a mono(fluoroalkyl) neutral fluorosurfactant, such as Zonyl® FSN fluorosurfactant, a fluoroalkyl-polyoxyethylene surfactant, can be added to the poly(fluoroalkyl) sugar reagent solution, the solution of the biomolecule to be immobilized, or the. support can be treated with the fluorosurfactant in a separate step either after or just preceding the immobilization step. The fluorocarbon surface can be a solid fluorocarbon polymer such as poly(tetrafluoroethylene) , a liquid fluorocarbon such as perfluorodecalin, or a nonfluorocarbon support that is coated with a fluorocarbon interlayer. The non-fluorocarbon core for preparing solid supports of this invention include inorganic surfaces such as silica, magnetic particles and polymers such as polystyrene, polypropylene and polyethylene. By interlayer is meant a layer of fluorocarbon coating located on the surface of the non-fluorocarbon solid carrier core. The fluorocarbon compound can be a fluoropolymer, fluorosilane or other highly fluorinated hydrocarbon chain. The interlayer may be applied to a non-fluorocarbon solid by spray coating or by chemical reactions. A sufficient amount of fluorocarbon surface must be present to secure the reagent and anchor the biomolecule. The poly(fluoroalkyl) sugar reagents of the present invention can be used in the preparation of supports for the separation of biomolecules, enzyme immobilization, heterogeneous diagnostic assays and biosensors. The main advantages of the poly(fluoroalkyl) sugar reagents over the mono(fluoroalkyl) reagents are: higher retention of biological activity, higher immobilization efficiency, more secure attachment of the biomolecule, a more stable preactivated support, and a simpler immobilization procedure. The supports described in this invention can be used for various kinds of extra- corporeal depletion therapy, for nucleic acid hybridization assays, to capture DNA or RNA from mixtures and for various configurations of solid and liquid phase bioassays. Below are the Experimental details for the synthesis of poly(fluoroalkyl) sugar reagents. The reagents will be numbered as shown below throughout the specification. REAGENTS 1 4. R Ac, R' - CH-CH2 5.

The particles •20 were then washed twice with 10 mL portions of 1:1 acetone-water. After the washes, the solution above the settled particles was removed with a disposable pipet. Poly(fluoroalkyl) sugar reagent 8 (described on page 21) was dissolved in acetone (2 mg/mL) , then enough water 25 was slowly added to give a 1:1 acetone-water mixture. At this point the solution may become slightly cloudy. The reagent solution (10 mL) was added to 1 gram of the washed particles and the suspension was stirred for 30 min to 1 h at room temperature to immobilize the reagent 30 onto the particles. After this time, the particles were washed twice with 10 mL portions of 1:1 acetone-water, followed by four washes with water. During the water washes the particles were stirred gently with a small spatula to prevent the entrapment of air within the 35 particles, which causes them to float. To immobilize chymotrypsin, 10 mL of a solution of the enzyme (1 mg/mL) in 0.1 M, pH 7.5 MOPS buffer was added to the activated particles, and the mixture was stirred for 2 h at room temperature. After immobilization, the particles were washed three times with MOPS buffer. Optionally, the particles were washed twice with 0.2% Zonyl® FSN fluorosurfactant in MOPS buffer for 15 min, followed by three more washes with MOPS buffer. The amount of chymotrypsin immobilized onto the particles was determined by measuring the amount- of protein remaining in the solution after immobilization and in the washes using a colorimetric protein assay. The activity of chymotrypsin was determined using N-benzoyl-L-tyrosine p-nitroanilide (BTpNA) as substrate. The rate of production of p-nitroaniline was measured at 385 nm. The molar absorption coefficient for p-nitroaniline at this wavelength is 1.258 x 10 4 . The substrate solution contained nine volumes of 0.04 M Tris buffer, pH 8.0, which was 0.005 M in calcium chloride and one volume of a solution of BTpNA in acetone (0.00178 M) . Aliquots of 2.9 mL of the substrate solution were added to 3 mL spectrophotometer cells, 0.1 mL of the diluted (1:10) stock enzyme solution was added, and the absorbance was measured at 2 min intervals for 16 min. To determine the enzyme activity immobilized on the particles, 50 uL of the settled suspension was added to 2.9 mL of the substrate solution. This mixture was incubated for 10 min at room temperature with vigorous stirring. The suspension was quickly transferred to a dry, preweighed centrifuge tube and centrifuged for 1 min. The supernatant was transferred to a spectrophotometric cell and the absorbance at 385 nm was measured. The remaining particles were quantitatively transferred to the centrifuge tube, washed several times with water, and dried in an oven at 120°C overnight. The dried particles were weighed the next day to obtain the weight of particles used in the assay. The immobilized enzyme activity per gram of particles and the retention of activity were calculated. The amount of chymotrypsin immobilized was 9.3 mg per gram of particles. The total enzymatic activity present on the particles was 1.2 IU per gram. The retention of enzymatic activity after immobilization was 33% of the original activity.

The amount of chymotrypsin immobilized was 9.1 mg per gram of particles, and the total activity was 1.2 IU per gram of particles. The retention of enzymatic activity after immobilization was 31% of the original activity. EXAMPLE 3 IMMOBILIZATION OF CHYMOTRYPSIN USING N-3'-(N- OXYSUCCINIMIDYLCARBONYL)PROPYL 2,3,4,5,6,7-HEXA-O-(3- PERFLUOROOCTYL)PROPIONYL GLUCOHEPTANAMIDE 32 The procedure described in Example 1 was used, except that the poly(fluoroalkyl) sugar reagent 32 was substituted for Reagent 8. The amount of chymotrypsin immobilized was 8.6 mg per gram of particles, and the total activity was 1.0 IU per gram of particles. The retention of enzymatic activity after immobilization was 40% of the original activity. EXAMPLE 4 IMMOBILIZATION OF CHYMOTRYPSIN USING 4'-(N- OXYSUCCINIMIDYLCARBONYL)BUTYL 2,3,4,6-TETRA-O-(3- PERFLUOROOCTYL)PROPIONYL-β-D-GLUCOPYRANOSIDE) AND NEUTRAL FLUOROSURFACTANT Fluorocarbon particles (0.5 g) were activated with poly(fluoroalkyl) sugar reagent 8, as described in Example 1. To immobilize the enzyme, 5.0 mL of a 1 mg/mL chymotrypsin solution in pH 7.5 MOPS buffer, containing 0.05% Zonyl FSN, was added to the particles. Chymotrypsin activity was determined spectro- photometrically by measuring the increase in absorbance at 256 nm resulting from the hydrolysis of benzoyl-L- tyrosine-ethyl ester (BTEE) . The assay mixture contained 1.5 mL of 0.08 Tris-HCl buffer, pH 7.8, with 0.1 M calcium chloride, and 1.4 mL of 1.07 mM BTEE in 50% methanol. The addition of the fluorosurfactant to the enzyme solution did not affect the amount of enzyme immobilized. However, the retention of activity increased to 50%. EXAMPLE 5 PENICILLIN AMIDASE IMMOBILIZATION USING 4'-(N- OXYSUCCINIMIDYLCARBONYL)BUTYL 2,3,4, 6-TETRA-O-(3- PERFLUOROOCTYL)PROPIONYL-β-D-GLUCOPYRANOSIDE) One gram of fluorocarbon particles was activated with poly(fluoroalkyl) sugar reagent 8 as described in Example 1. For penicillin amidase immobilization, the stock enzyme solution (950 IU/mL, 81.5 mg protein/mL) was diluted ten-fold with 0.1 M, pH 7.5 MOPS buffer. Two milliliters of this enzyme solution was added to one gram of activated particles, and the suspension was stirred for 2 h at room temperature. The particles were washed three times using 0.02 M, pH 8.0 phosphate buffer. The amount of protein immobilized was determined from the depletion of enzyme activity from the original enzyme solution and the activity present in the washes. Penicillin amidase activity was determined using a method based on the transformation of penicillin G into 6-aminopenicillinate and phenylacetic acid, catalyzed by penicillin amidase. The rate of the reaction was determined using a pH Stat to measure the rate of consumption of sodium hydroxide. The substrate sodium penicillin G was dissolved in 0.02 M, pH 8.0 phosphate buffer to give a 5% solution. Ten milliliters of the substrate solution was added to the reaction vessel of the pH Stat, and 50 uL of enzyme solution was added. The rate of addition of 0.1 M sodium hydroxide solution, required to maintain a pH of 8.00, was recorded for 10 min. The specific activity of the enzyme was calculated from the measured reaction rate. The immobilized enzyme activity was determined in the same way as the soluble enzyme, using 100 uL of the settled particles in 10.0 mL of the substrate solution. The particles were collected, washed with water, and dried after completion of the assay. The amount of penicillin amidase immobilized was 5.6 mg per gram of support, and the retention of activity was 51%. In control experiments in which the fluorocarbon particles were not treated with the sugar reagent, 8.6 mg of penicillin amidase was adsorbed onto the fluorocarbon particles, but no enzymatic activity was detectable. EXAMPLE 6 IMMOBILIZATION OF PENICILLIN AMIDASE ON POROUS SILICA TREATED WITH FLUOROSILANES A. Preparation gf Porous Silica Based Support Fifty grams of silica gel (Zorbax™ PSM 300) coated with zirconium oxide by the procedure as described in U.S. 4,600,646 to Stout, incorporated herein by reference, were heated and stirred in a mixture of 350 mL of toluene and 40 mL of dimethylformamide (DMF) containing 57 g of imidazole under a Dean-Stark trap. A 50-mL fraction of the distillate was removed and the residual silica mixture was allowed to cool to approximately 50°C. To attach a fluorosilane interlayer onto the silica, the Dean-Stark trap was removed and 80 g of heptadecafluoro-1,1,2,2-tetrahydrodecyldichloro- methyl silane (HDF-silane) was added to the silica mixture. The silica-HDF-silane mixture was refluxed for two hours, cooled and filtered. The HDF-silane-coated silica was then washed with 80% aqueous tetrahydrofuran (THF) , resuspended in 350 mL of 80% aqueous THF and refluxed for 5 minutes. The HDF-silane-coated silica was cooled to 50°C, filtered and twice washed with 200 mL of THF per wash. The coated silica was resuspended in 350 mL of 80% aqueous THF, refluxed for 10 minutes, filtered, twice washed with 200 L of THF per wash and twice washed with 200 mL of Freon® TF per wash. The resulting coated silica was dried first in air and finally in a vacuum oven at 110°C. B. Immobilization on Porous Silica One gram of porous silica (Zorbax™ PSM300) , treated with fluorosilane was activated with 100 mg of poly(fluoroalkyl) sugar reagent 8, as described in Example 1. The amount of protein immobilized, determined as described in Example 5, was 69 mg per gram of particles, and the retention of activity was 7%. EXAMPLE 7 IMMOBILIZATION OF PROTEIN A USING 4' (N-OXYSUCCINIMIDYLCARBONYL)BUTYL 2,3,4,6-TETRA-O-(3-PERFLUOROOCTYL)PROPIONYL- β-D-GLUCOPYRANOSIDE 8 One gram of fluorocarbon particles was washed twice with 10 mL portions of HPLC-grade acetone. The particles were then washed twice with 10 mL portions of acetone/water (1:1 v/v). After the washes, the solution above the settled particles was removed with a disposable pipet. Poly(fluoroalkyl) sugar reagent 8 (3 or 4 mg) was dissolved in acetone (2 mL) , and water (2 mL) was slowly added to give an acetone/water (1:1 v/v) solution. At this point the solution may become slightly cloudy. The reagent mixture (4 mL) was added to 1 gram of the washed particles and the suspension was stirred for 30-60 minutes at room temperature to immobilize the reagent onto the particles. After this time, the particles were washed three times with 10 mL portions of acetone/water (1:1 v/v), followed by three washes with 10 mL portions of cold 0.1 M sodium phosphate buffer, pH 8.5. During the buffer wash the particles were stirred gently to prevent the entrapment of air within the particles, which causes them to float. Protein A was immobilized by adding 1.4 or 1.8 mL of a cold protein A solution (5 mg/mL) in 0.1 M sodium phosphate buffer, pH 8.5, to the activated particles, and stirring the mixture overnight at 4°C. After immobilization, the particles were washed three times with 5 mL portions of 0.1 M sodium phosphate buffer, pH 8.5, followed by washing five times with 5 mL portions of 0.2% Zonyl® FSN fluorosurfactant in 0.1 M sodium phosphate buffer, pH 8.5. Finally, the particles were washed three times with 5 ml- portions of 0.1 M sodium phosphate buffer, pH 8.5. The amount of protein A immobilized onto the particles was determined by measuring the amount of protein remaining in the solution after immobilization and in the washes, using a colorimetric protein assay. The activity of immobilized protein A was determined by measuring the binding of human immunoglobulin (hlgG) to protein A at pH 8.0, followed by release of the hlgG at pH 3.0. The particles with immobilized protein A were quantitatively packed into a small (1.25 mL) polypropylene chromatography column, which was connected to a pump, set at a flow rate of 2.0 mL/min, and a UV detector, set at 280 n , equipped with a recording integrator. The column was first equilibrated with 3 mL of 0.1 M sodium phosphate buffer, pH 8.0, and a baseline was established for the integrator. Then 2.5 mL of a 10 mg/mL solution of hlgG in 0.1 M sodium phosphate buffer, pH 8.0, was pumped onto the column followed by 5.5 mL of the buffer. Finally, 5 mL of 0.1 M glycine-HCl buffer, pH 3.0, was pumped through the column to release the bound hlgG. The binding capacity of the immobilized protein A for hlgG was calculated by multiplying the amount of hlgG loaded onto the column (25 mg) with the area integrated for the released hlgG (as a fraction of the total integrated area) . The volume of particles in the column was determined and the hlgG binding capacity recalculated as mg/mL.
