The A9 cell line, frequently used for cell hybridization, is deficient in both HPRT and APRT. Evidently the parent L cell line from which A9 was derived had previously undergone a spontaneous mutation to APRT deficiency. The double enzyme deficiency in A9 cells should be recognized by investigators who use this line for studies on somatic cell genetics.
