Karyotype
modal number = 46; range = 42 to 48.
This is a pseudodiploid human cell line. The modal chromosome number is 46 occurring at 68% and polyploidy at 0.4%. Three marker chromosomes were detected in all metaphases examined. Two markers that appeared to be the product of the balanced translocation between N1 and N17. The third marker is ?inv(13). No other common markers were detected. Normal N1, N13, and N17 had single-copy each. Y chromosome is present.
