Abstract excerpt
By a sequential mutation and selection utilizing N-methyl-N'-nitro-N-nitrosoguanidine as a mutagen, we succeeded in separating a poly(ADP ribose) polymerase-defective mutant clone (Cl-3527) from a mouse L1210 cell clone (Cl-3). The enzyme activity per cell in Cl-3527 cells was only 8% of that in wild type L1210 (CCL 219) cells. Immunoblot analysis of the enzyme protein in crude extracts of the mutant and wild...
