Bleomycin B2 sulfate
Based on 1 Customer Validation
Bleomycin B2 (Phleomycin D2) sulfate is a selective antitumor and antibacterial agent that induces DNA strand breaks and inhibits DNA ligase activity. The optimal pH for the activity of Bleomycin B2 sulfate is 9.1, and its efficacy is enhanced by thiol compounds or hydrogen peroxide. Bleomycin B2 sulfate undergoes enzymatic inactivation via bleomycin-inactivating enzymes, exhibits selective retention in squamous cell carcinoma, and is inactivated most rapidly in liver and kidney homogenates. Bleomycin B2 sulfate can be applied in research related to squamous cell carcinoma and other relevant studies.

Biological Activity
|
DNA Ligase |
Bleomycin B2 sulfate (1000 μg/mL; 30 min) undergoes the fastest inactivation in mouse liver and kidney homogenates, with only 6.8% and 5.0% of activity remaining, respectively; whereas its inactivation is the slowest in mouse lung and skin homogenates, with 40.2% and 34.2% of activity remaining, respectively[1].
Bleomycin B2 sulfate (100 μg/mL; 60 min) is potently inactivated by partially purified mouse liver bleomycin-inactivating enzyme at 37°C; complete inactivation is achieved after 60 min when the enzyme concentration is ≥1 mg protein[1].
The inactivation activity of Bleomycin B2 sulfate by the enzyme protein extracted from mouse sarcoma tissues induced by 20-methylcholanthrene is significantly higher than that by the enzyme protein extracted from mouse squamous cell carcinoma tissues induced by 20-methylcholanthrene (mean 32.71 units/g vs mean 14.45 units/g)[1].
Bleomycin B2 sulfate (0.1-40 μg/mL; 2-60 min) induces single-strand breaks in supercoiled SV40 DNA in a cell-free system, and its activity is increased 20-fold in the presence of 1 mM 2-mercaptoethanol[2].
