     BACKGROUND OF THE INVENTION 
     The centromere is a specialized region of the eukaryotic chromosome. It is the site of kinetochore formation, a structure which allows the precise segregation of chromosomes during cell division. In addition to this, a possible structural role in the higher-order organization of eukaryotic chromosomes has also been suggested (Hadlaczky (1985), Internatl. Rev., 94:57-76). 
     The isolation and cloning of centromeres is crucial, not only to understanding their molecular structure and function, but also for the construction of stable artificial chromosomes. Taking advantage of the existence of centromere-linked genes, functional centromeres of lower eukaryotes (yeast) have been successfully isolated (Blackburn, et al. (1984) Ann. Rev. Biochem., 53:163-194; Clarke, et al. (1985), Ann. Rev. Genet., 19:29-56). The combination of a functional centromere with telomeres, which stabilize the chromosome ends, permitted the construction of yeast artificial chromosomes (Murray, et al. (1983) Nature, 305:189-193; Burke, et al. (1987), Science, 236:806-812). This initiated a new era in the study of chromosome function and in genetic manipulation. 
     Higher eukaryotes (e.g., mammals), in contrast to yeast, contain repetitive DNA sequences which form a boundary at both sides of the centromere. This highly repetitive DNA interacting with certain proteins, especially in animal chromosomes, creates a genetically inactive zone (heterochromatin) around the centromere. This pericentric heterochromatin keeps any selectable marker gene at a considerable distance, and thus repetitive DNA prevents the isolation of centromeric sequences by chromosome &#34;walking.&#34; 
     Thus there is a need in the art for methods of isolating higher eukaryotic centromeric DNA. Isolation of such DNA is necessary for construction of artificial mammalian chromosomes. Use of such chromosomes could overcome problems inherent in present techniques for introduction of genes to mammalian cells, including the concomitant creation of insertional mutations, size limitations on introduced DNA, and imperfect segregation of plasmid vectors.

     DETAILED DESCRIPTION 
     It is the discovery of the present invention that a segment of human DNA can be isolated and introduced into mouse cells and results in a functional centromere. The functional centromeres containing DNA of the present invention are preferably linked to a dominant selectable marker. This can be a resistance marker, such as the aminoglycoside-3&#39; phosphotransferase-II which provides resistance to G418 (Sigma). Other such markers known in the art may be used. 
     The method of isolating centromeric DNA of the present invention can be applied to any higher eukaryote, especially mammals. Preferably a human cell line will be employed. Metaphase chromosomes are isolated according to techniques known in the art. The chromosomes are then fragmented. Endonuclease digestion and mechanical shearing can be used to fragment the chromosomes. Desirably the majority of the fragments will be in the size range of less than 1 μm and some chromosomes will remain unbroken. Unbroken chromosomes can be readily removed from the preparation by centrifugation at about 1,500 g for about 10 minutes. 
     A human serum containing anti-centromere autoantibodies can be employed in the method of the invention. This is available from patients with CREST syndrome. Alternative sources of antibody may be used, such as monoclonal or animal derived polyclonal sera containing anti-centromere antibodies. The antibodies are incubated with the preparation of chromosome fragments under conditions where antibody-antigen complexes form and are stable. It is convenient if the antibodies are bound to a solid support. Preferably a support such as Protein-A Sepharose CL4B (Pharmacia) is used to facilitate separation of bound from unbound chromosomal fragments. However other methods to accomplish this goal can be used, as are known in the art, without employing an antibody bound to a solid support. 
     The DNA fragments comprising centromere DNA are liberated from the antibodies and centromeric proteins by a deproteinization treatment. Ultimately the DNA is purified from all proteins, by degrading the proteins and extracting them from the chromosome fragment preparation. Any such treatment known in the art may be used including but not limited to proteases and organic solvents such as proteinase K and phenol. 
     The centromeric DNA fragments can be used for any purpose or application known in the art. For example, they can be labelled and used as probes; they can be ligated to vectors to clone or all part of the sequences; and they can be used to purify centromeric proteins by attachment to a solid support. 
     In one particular embodiment of the invention the centromeric DNA fragments are used to probe a library of genomic DNA from humans or other mammals for clones which hybridize. Hybridizing clones can be analyzed for their ability to perform functions which centromeric DNA possesses. One such function is to bind to centromeric proteins. Another such function is to form a structure in cells which can be cytologically detected using appropriate immunostaining with anti-centromere antibodies which particularly stain centromeres. 
     According to another method of the present invention a cell carrying an excess of mammalian centromeres is formed. The cell may be human or other mammalian. The centromere may comprise DNA isolated from the same or a different mammalian species as the cell. The method involves cotransfection of a cell with two DNA molecules: one is a DNA carrying centromeric DNA; the other is a DNA carrying a dominant selectable marker. Preferably these two DNA molecules contain sequences which allow concatamer formation, for example phage DNAs such as λ phage. The first DNA molecule may be isolated from a library of genomic DNA using, for example, as a probe the centromeric fragments taught above. Alternatively the first DNA molecule may result from cloning the centromeric fragments taught above into a phage, for example λ, after manipulations to create fragments of the appropriate sizes and termini. The second DNA molecule is readily within the reach of those of skill in the art, for example aλ phage carrying a drug resistance marker. 
     It is believed to be desirable to employ λ phage DNA because it concatemerizes, however the absolute necessity of this has not been determined. Further, even if this property is necessary, other viral DNAs or DNA constructs may be able to supply this function. Such other means of achieving concatemerization are also contemplated within this method. 
     After cotransfection, cells are selected which express the dominant selectable marker, for example by growth in amounts of G418 which are cytotoxic for the cells without the marker. This selected population of cells is further screened to detect cells with an excess of mammalian centromeres. This screening can be done by standard cytogenetic techniques, as well as by immunostaining with anti-centromere antibodies. Desirably the lambda, marker, and centromeric DNA (from the λ clone) will all be localized at the site of the extra centromere. This can be determined by in situ hybridization studies, which are well known in the art. 
     One cell line made by the methods described above is EC3/7 which has been deposited at the European Collection of Animal Cell Cultures, Porton Down, U.K. under accession no. 90051001, under the conditions of the Budapest Treaty. 
     The sequence of the DNA insert in the lambda phage which was used to make the EC3/7 cell line, (referred to as CM8) was determined by standard techniques and is shown in FIG. 1. The sequence does not correspond to any in DNA sequence banks. 
     The present invention also contemplates nucleic acid probes, preferably of at least 10 nucleotides, which hybridize to a DNA molecule having the sequence shown in FIG. 1. One such molecule is CM8, the lambda phage clone from which the sequence was derived. Probes can be radiolabeled, biotin labeled or even unlabeled, for example, depending on the use for which they are desired. 
     The following examples do not limit the invention to the particular embodiments described, but are presented to particularly describe certain ways in which the invention may be practiced. 
     EXAMPLE 1 
     This example demonstrates the isolation of human DNA from centromeres. 
     Human colon carcinoma cell line (Colo 320) was grown as a suspension in RPMI medium supplemented with 10% foetal calf serum (FCS). Metaphase chromosomes of Colo 320 cells were isolated by our standard method (Hadlaczky, et al. (1982), Chromosomes, 86:643-659). Isolated metaphase chromosomes were resuspended in 1 ml of buffer (105 mM NaCl, 50 mM Tris-HCl pH 7.5, 10 mM MgCl 2 , 5 mM 2-mercaptoethanol) at a concentration of 1 mg/ml DNA and digested with 500 u EcoRI restriction endonuclease for 1 h. The suspension was diluted with 4 ml of IPP buffer (500 mM NaCl, 10 mM Tris-HCl, 0.5% NP-40, pH 8.0) and sonicated for 5×50 s with an MSE 5-70 sonicator. This treatment resulted in a suspension containing chromosome fragments and a few (&lt;1%) unbroken small chromosomes. The suspension was centrifuged at 1500 g for 10 min to remove unbroken chromosome fragments. The supernatant contained only small (&lt; --  1 μm) chromosome fragments as judged by light microscopy. 
     Two hundred fifty mg of Protein-A Sepharose CL4B (Pharmacia) was swollen in IPP buffer and incubated with 500 μl human anti-centromere serum LU851 (Hadlaczky, et al. (1989), Chromosoma, 97:282-288) diluted 20-fold with IPP buffer. Suspension of sonicated chromosome fragments (5 ml) was mixed with anti-centromere Sepharose (1 ml) and incubated at room temperature for 2 h with gentle rolling. After 3 subsequent washes with 25 ml IPP buffer the Sepharose was centrifuged at 200 g for 10 min. 
     Isolation of DNA from the immunoprecipitate was carried out by Proteinase-K treatment (Merck, 100 μg/ml) in 10 mM Tris-HCl, 2.5 mM EDTA, pH 8.0 containing 1% SDS, at 50° C. overnight, followed by repeated phenol extractions and precipitation with isopropanol. All general DNA manipulations were done according to (Maniatis, et al. (1982) Molecular Cloning--A Laboratory Manual (Cold Spring Harbor Laboratory, Cold Spring Harbor, N.Y.). 
     Results of electrophoresis of immunoprecipitated and supernatant DNA are shown in FIG. 2. The bulk of DNA from chromosome fragments which did not bind to the anti-centromere Sepharose (supernatant) ranged from several hundred base pairs to 5 kb (FIG. 2, lanes A and B), while DNA from chromosome fragments which bound to the anti-centromere Sepharose contained an additional population of high molecular weight (9-20 kb) fragments (FIG. 2, lanes C and D). This distribution of fragments sizes is consistent with the notion that the centromeric DNA is in the structurally most stable region of mammalian chromosomes (Hadlaczky, et al. (1981), Chromosoma, 81:557-567), thus rendering this DNA relatively resistant to enzymatic digestion and mechanical shearing. 
     EXAMPLE 2 
     This example demonstrates the use of the high molecular weight immunoprecipitated DNA as a hybridization probe to screen a genomic DNA library. 
     The high molecular weight DNA was isolated from the agarose gel described in Example 1, by electroelution, labelled with  32  P-dATP by random oligonucleotide priming (Feinberg, et al. (1983), Anal. Biochem., 132:6-13) and used as a probe for screening a λ Charon 4A human genomic library (Maniatis, et al. (1978), Cell, 15: 687-701). A hybridizing clone (CM8) was obtained which contains a 14 kb human DNA insert. The restriction map of this insert for some restriction endonucleases is shown in FIG. 3. Southern hybridization of parts of the 14 kb insert to human lymphocytic genomic DNA indicates that the 14 kb insert represents a continuous piece of DNA in the genome and is not the ligation product of a number of fragments. 
     EXAMPLE 3 
     This example demonstrates that the copy number of the 14 kb insert of clone CM8 is consistent with it being present on each chromosome in the human genome. 
     Southern blotting experiments were performed in which a single copy DNA probe (XV2C) (Estivill, et al. (1987), Nature, 326:840-845) and the central XhoI-EcoRI fragment of the CM8 insert (FIG. 2) simultaneously hybridized with serial dilutions of human peripheral lymphocyte DNA. The probes were labelled by random oligonucleotide priming (Feinberg, et al. (1983), Anal. Biochem., 132:6-13). By comparing the signal of the CM8 probe to the known single copy probe, the copy number of CM8 was estimated to be 16-32 per haploid genome. 
     EXAMPLE 4 
     This example shows the use of the CM8 DNA as a probe to human metaphase chromosomes. 
     Radioactive in situ hybridization with  3  H-thymidine labelled CM8 DNA to human (Colo 320) metaphase chromosomes was performed according to the method of Pinkel, et al. (1986), Proc. Natl. Acad. Sci. U.S.A., 83:2934-2938. A preferential centromeric localization of silver grains was observed (FIG. 4). 
     In non-radioactive in situ hybridization according to the method of (Graham, et al. (1973), Virology, 52:456-467), using biotin-labelled subfragments or the whole CM8 insert it was not possible to detect a positive hybridization signal by our standard method. Furthermore, using a hybridization method which is suitable for single copy gene detection with a biotin-labelled probe (Lawrence, et al. (1988), Cell, 52:51-61), apart from the typical R-band like Alu hybridization pattern (Korenberg, et al. (1988), Cell, 53:391-400), no specific hybridization signal was detected on any of the chromosomes with the whole 14 kb CM8 insert. Possible explanations for this negative result are that these sequences are virtually inaccessible to the hybridization probe, due to their compact packing in the midst of the centromere structure, and that the biotin system is less sensitive than the radioactive one. 
     EXAMPLE 5 
     This example discloses the sequence of the human CMB clone. 
     The sequence of the human genomic insert of λ CM8 was determined using the dideoxy method (Sanger, et al. 91980), J. Mol. Biol., 143:161-178; Biggin, et al. (1983), Proc. Natl. Acad. Sci. U.S.A., 80:3963-3965). See FIG. 1. 
     The sequence of the 13,863 bp human CM8 clone was compared with a complete nucleic acid data bank (MicroGenie, Beckman) and showed no homology to any known sequence. However, a 300 bp Alu repeat deficient in the flanking direct repeat sequences was found in the 2.5 kb EcoRI-XhoI fragment (FIG. 3), which explains the Alu type in situ hybridization pattern. 
     EXAMPLE 6 
     This example demonstrates the use of the CM8 DNA to form centromeres in mammalian cells. 
     In order to detect any in vivo centromere function of the CM8 DNA, it was introduced with the selectable APH-II gene into mouse LMTK -  fibroblast cells. The mouse fibroblast cells were maintained as a monolayer in F12 medium supplemented with 10% FCS. The calcium phosphate method (Harper, et al. (1981), Chromosoma, 83:431-439) was used to transfect the cells with 20 μg λ CM8 and 20 μg λ gtWESneo DNA per Petri dish (80 mm). A 2 minute glycerol shock was used. The λgt WESneo was made by cloning the pAG60 plasmid (Colbere-Garapin, et al. (1981), J. Mol. Biol., 150:1-14) into a λ gtWES (Leder, et al. (1977), Science, 196:175-177) bacteriophage vector. 
     The whole λ CM8 and λ gt WESneo constructions were used for transfections for two reasons. First, to separate the marker gene from the CM8 sequences, in order to avoid inactivating the APH-II gene, a process which may occur during centromere formation. Second, λ DNA is capable of forming long tandem arrays of DNA molecules by concatamerization. Concatamerization was postulated as being necessary to form centromeres since, in S. pombe 4 to 15 copies of conserved sequence motifs form centromeres (Chikashige, et al. (1989), Cell, 57:739-751). Considering these two facts a multiplication of the putative centromeric DNA by concatamerization might increase the chance of centromere formation. 
     Transformed cells were selected on growth medium containing 400 μg/ml G418 (Genticin, Sigma). Individual G418 resistant clones were analyzed. The presence of human sequences in the transformed clones was monitored using Southern blots probed with subfragments of the CM8 insert. Screening for excess centromeres was achieved by indirect immunofluorescence using human anti-centromere serum LU851 (Hadlaczky, et al. (1989), Chromosoma, 97:282-288). The chromosomal localization of &#34;foreign&#34; DNA sequences was determined by in situ hybridization with biotin labelled probes. 
     Eight transformed clones have been analyzed. All of the clones contained human DNA sequences integrated into mouse chromosomes. However, only two clones (EC5/6 and EC3/7) showed the regular presence of dicentric chromosomes. Individual cells of clone EC5/6 carrying di-, tri-, and multicentromeric chromosomes exhibited extreme instability. In more than 60% of the cells of this cell line the chromosomal localization of the integrated DNA sequences varied from cell to cell. Due to this instability, clone EC5/6 was deemed to be unsuitable. However, cells of clone EC3/7 were stable, carrying either a dicentric (85%) or a minichromosome (10%). Centromeres of dicentric chromosomes and minichromosomes were indistinguishable from the normal mouse centromeres by immunostaining with anti-centromere antibodies (FIGS. 5A and B). 
     EXAMPLE 7 
     This example shows that the newly introduced DNA in the EC3/7 cell line contributes to centromere formation. 
     In situ hybridization with biotin labelled CM8, APH-II gene, and λ phage DNA were carried out. Chromosomes were counterstained with propidium iodide (Pinkel, et al. (1986), Proc. Natl. Acad. Sci. U.S.A., 83:2934-2938) for in situ hybridization experiments while in indirect immunofluorescence with DNA binding dye, Hoechst 33258 used. All observations and microphotography were made by using an Olympus AHBS Vanox microscope. Forte 400 Professional black and white, and Fujicolor 400 Super HG colour film were used for photographs. 
     Without exception these three probes hybridized onto the same spots: either on the distal centromere of the dicentric chromosome (FIG. 5C) or on the centromere of the minichromosome (FIG. 5D). In less than 5% of the EC3/7 cells an alternative localization of the hybridization signal was found. These included cells with more than one integration site, cells without a detectable signal, or cells where the hybridization was found on chromosomes other than that identified as the dicentric chromosome. 
     In less than 0.5% of the cells a tandem array of the hybridization signal was observed on the dicentric chromosomes (FIGS. 6A-C), suggesting that the additional centromere was capable of autonomous &#34;duplication.&#34; At least some of these duplicated centromeres appeared to be functional. This was indicated by the existence of a minichromosome with double centromeres. Both centromeres of this minichromosome showed positive immunostaining with anti-centromere antibodies (FIG. 7A). Minichromosomes carrying double centromeres might be breakage products of multicentromeric chromosomes. 
     Indirect immunofluorescence of mouse metaphase cells was performed as described by Hadlaczky, et al. (1989), Chromosoma, 97:282-288. When indirect immunofluorescence and in situ hybridization were performed on the same metaphases, mitotic cells were resuspended in a glycine-hexylene glycol buffer (Hadlaczky, et al. (1989), Chromosoma, 97:282-288), swollen at 37° C. for 10 min followed by cytocentrifugation and fixation with cold (-20° C.) methanol. After the standard immunostaining (Hadlaczky, et al. (1989), Chromosoma, 97:282-288) metaphases were photographed, then coverslips were washed off with phosphate buffered saline and slides were fixed in ice-cold methanol-acetic acid, air-dried and used for in situ hybridization. 
     To demonstrate the integration of the human CM8 clone sequence and the APH-II gene in the centromere region, immunostaining of centromeres with anti-centromere antibodies followed by in situ hybridization with CM8 and APH-II probes was carried out on the same metaphase plates of EC3/7 cells. The in situ hybridization signals with both biotin-labelled CM8 and APH-II probes showed a colocalization with the immunostained centromeric region of the chromosomes carrying additional centromeres (FIG. 7). 
     EXAMPLE 8 
     This example describes the stability of the EC3/7 cell line. 
     Forty-six independent subclones derived from a single cell were isolated and analyzed. Each of the subclones carried the dicentric chromosome. The percentage of minichromosome-containing cells varied between 2% and 30% in different subclones. We were unable to isolate a subclone which carried the additional centromere exclusively in a minichromosome. This result suggested that the minichromosomes were unstable and they can be regarded as the products of regular breakages of the dicentric chromosomes. 
     A preliminary analysis by immunostaining of EC3/7 cells (103 metaphases) cultured for 46 days in non-elective medium showed that 80.6% of the cells contained either a dicentric (60.2%) or a minichromosome (20.4%). Subsequent in situ hybridization with biotin labelled probes proved the presence of the &#34;foreign&#34;, DNA in the additional centromere. These results indicate that no serious loss or inactivation of the additional centromeres had occurred during this period of culture under non-selective conditions. 
     EXAMPLE 9 
     This example shows that the CM8 insert concatamerized to form the functioning centromere of cell line EC3/7. 
     DNA of the EC3/7 cell line and human lymphocyte DNA were digested with restriction endonucleases and probed with subfragments of the CM8 insert in a Southern hybridization experiment. Comparing the intensity of the hybridization signal with EC3/7 DNA to that with the human DNA, the minimum number of integrated human sequences in the additional centromere was estimated to be ≧30. The copy number of CM8 in human lymphocytic DNA was determined as described above in Example 3.
