Description
 Bleomycin Sulfate is an anti-cancer agent isolated from Streptomyces verticillus.  Bleomycin is a mixture of bleomycin A2 and bleomycin B2, in an approximately 2:1 ratio, respectively.  However, the ratio varies by lot number. 
  Bleomycin is used against Hodgkin’s lymphoma.  Its mechanism is not well understood; however, it is though that bleomycin chelates metallic ions causing a decrease in enzyme stability.  The enzymes react with oxygen and produce free radicals, ultimately causing single-stranded breaks in deoxyribose sugars of DNA.
