A Study on Chromosome of K₅₆₂ Cells for the Use of Target Cells in Human Natural Killer Cell Assay

The metaphase chromosomes of the K₅₆₂ Cell lines stained with trypsingiemsa method were observed and the results obtained are summarized as fellowing; 1) The chromosome types were classified according to the position of centromere. 2) The K₅₆₂ cells were aneuploid with a prominent, pseudotriploid mode. 3) Chromosome numbers were varied from 43 to 75. 4) The most frequent chromosomal number was 6027.0%) 5) Single chromatid break were observed in the long arms of chromosome No.6 and No.11 6) In the karyotypic analysis, it was appeared that all the cells contained at least four markers.
