Bleomycin an Antitumor Antibiotic: Improved Microbiological Assay and Tissue Distribution Studies in Normal Mice

摘要

A microbiological assay was developed for bleomycin, an antitumor antibiotic reported to be active in human trials. The assay bacterium was a strain of Escherichia coli which is resistant to ethionine. Studies revealed relatively high concentrations of bleomycin in the blood and urine of mice after a single dose, < 0.33 ld10, injected intraperitoneally.
