Rapid technique for the detection of carcinogens using mice liver microsomes.

Mice liver microsomes were prepared at low g (10,000 g) force by Ca(2+)-aggregation method and were used for the detection of carcinogens by degranulation technique. RNA/protein ratio of these microsomes was 0.177 which was comparable to rat liver microsomes. Per cent degranulation with two carcinogens (O-dianisidine and benzidine) at 20 micrograms concentration was 21 per cent on the basis of RNA/protein ratio basis with both the carcinogens. At 40 micrograms concentration the per cent degranulation was observed to be almost double. Both the carcinogens required NADPH for their activation.
