[Use of an express method in studying the cytotoxic action of antitumor antibiotics].

The cytostatic effect of some antitumor antibiotics such as carminomycin, olivomycin, bruneomycin, rubomycin C and adriamycin was studied with a rapid method based on measurement of 3H-thymidine and 14C-adenine incorporation into the tumor cells of suspended primary cultures of mouse lymphadenosis NK/Ly. The method is recommended for screening of antitumor antibiotics.
