Bleomycin sulfate is a water soluble anticancer chemotherapeutic agent commonly used to treat Hodgkin’s lymphoma. Bleomycin comprises a mixture of two components: bleomycin A2 and bleomycin B2. The approximate composition of A2:B2 is 2:1; however, the ratio can vary greatly depending on the lot tested.
TOKU-E offers three forms of bleomycin: bleomycin sulfate (B005), bleomycin A2 sulfate, EvoPure® (B019), and bleomycin B2 sulfate, EvoPure® (B020). EvoPure® products are individual molecular fractions, most >99% pure.
Mechanism of Action
Bleomycin acts as an anticancer agent by causing single stranded breaks in DNA. The exact mechanism is not well defined however; it is thought to chelate metallic ions to decrease enzyme activity and stability. This effect is believed to cause enzymes to react with oxygen producing free radicals which create single stranded breaks in deoxyribose sugar.
