Abstract
A cell line resistant to 6-mercaptopurine (6-MP) is isolated from Djungarian hamster embryonic fibroblasts transformed with SV-40 virus. 6-MP resistance is due to the absence or complete inhibition of HGPRT [hypoxanthine guanine phosphoribosyl transferase] activity. Initial and resistant cell cultures are similar in the growth rate and in the inoculation efficiency. Karyological analysis (differential chromosome staining.sbd.S-bands) revealed considerable karyotype rearrangements in both resistant and sensitive lines as compared with Djungarian hamster normal chromosome set, and the appearance of specific chromosome markers.This publication has 1 reference indexed in Scilit:
