Title: Methods for detection and quantitation of cell subsets within subpopulations of a mixed cell population
Inventor: MELINICOFF MERYLE J
IPC: C07D263/62
Filed: 1991-11-05
Abstract: The presence or quantity of a selected subset of cells, which is part of a subpopulation of a mixed cell population, is determined by a method in which a detectable reporter substance is uniformly incorporated into substantially all cells of the subpopulation containing the subset of interest. The subset of interest is then affinity-separated by incubating a test sample of the mixed cell population containing the labeled subpopulation with a specific binding substance which selectively binds to characteristic determinants of the cell subset of interest. Occurence of the reporter substance in the separated fraction is then detected, and correlated to a predetermined standard to determine the presence or quantity of the subset of interest within the cell population.  According to another aspect of the invention a method is provided for quantitating two or more selected subsets of cells within a subpopulation of a mixed cell population. After labeling, the entire subpopulation is affinity-separated from the mixed cell population, and occurence of the reporter substance in the separated fraction is detected. Next, subsets of interest within the subpopulation are affinity-separated as described above, and the level of detected reporter substance in each subset is compared to the level detected in the entire subpopulation. According to further aspects of the invention test kits are provided for performing the above-described methods.

Title: Preparation of porous polyester beads
Inventor: MAIER THOMAS R
IPC: C08J3/14
Filed: 1993-08-20
Abstract: Abstract of the Disclosure PREPARATION OF POROUS POLYESTER BEADS        High molecular weight polyethyleneterephthalate resin is currently being used in vast quantities in manufacturing tire cord and in manufacturing trays for frozen foods which can be heated in either microwave or convection ovens. In some applications polyester resins having ultra-high molecular weights are required.  For example, some techniques for producing polyester yarn by solution spinning demand ultra-high molecular weight polyester.  Unfortunately, it becomes progressively more difficult and expensive to produce polyester resins having higher and higher molecular weights utilizing standard commercial polymerization techniques.  This invention discloses a technique for preparing porous polyester beads which can be solid state polymerized very rapidly to ultra-high molecular weights.  This invention more specifically discloses a process for preparing ultra-high molecular weight polyester resin which comprises:  (1) dissolving a polyester prepolymer in a suitable organic solvent to produce a polyester prepolymer solution; (2) allowing droplets of the polyester prepolymer solution to drip into a coagulation bath to produce porous polyester beads; (3) recovering the porous polyester beads from the coagulation bath; (4) removing residual organic solvent from the porous beads; and (5) solid state polymerizing the porous polyester beads at an elevated temperature to produce the ultra-high molecular weight polyester resin.
