摘要

32p标记的大肠杆菌WP-2和WP-2S细胞在零下196度保存。32P衰变对两菌株的致死作用相同。32P致DNA 32P突变的致死效率为0.046。在UV敏感菌株WP-2S中,与WP-2相比,可诱导出10倍于WP-2S的反复性try+。

Comparison of mutagenic efficiency of decay of 32P incorporated in E. coli WP-2 and E. coli WP-2S cells.

32P-labeled Escherichia coli WP-2 and Escherichia coli WP-2S cells were stored at minus 196 degrees. The lethal effect induced by 32P decay was equal in both strains. Lethal efficiency of 32P leads to 32P transmutation in DNA amounted to 0.046. Reversion try leads to try+ were induced with a ten times higher efficiency in UV--sensitive strain WP-2S, as compared with strain WP-2.
