Figure 3.
Clonal cell survival of ES cells differing in Rev1 mutation. Cells were seeded on gelatin-coated plates and 15 h later exposed to UV-C, 4-NQO or MNU. Then, cell populations were seeded at clonal cell density to determine the clone forming ability. The clone forming ability of unexposed cells was set at 100%. Closed circle, wild type; closed triangle, Rev1B/B-254; closed square, Rev1B/B-243.
