Bleomycin sulfate (BLENOXANE®) is a mixture of cytotoxic glycopeptide antibiotics produced by a strain of streptomyces verticillus. This component is known to cause single and/ or double-stranded breaks in DNA through approximating metals and coordinate dioxygen to generate the active species.
Bleomycin sulfate treatment resulted in elongation of E. coli cells and enlargement of HeLa cells through inhibiting DNA and protein syntheses [1].
This component is widely used in the treatment of Hodgkin's lymphoma in combination with doxorubicin, testicular cancer, squamous cell carcinomas, pulmonary fiborosis as well as in the treatment of plantar warts. For instance, Bleomycin sulfate was also shown to have
moderate to marked effects upon Rous sarcoma virus induced mouse ascites sarcoma, particularly when F1 hybrid mice were employed as host animals [2]. In addition, recent studies support the role of the proinflammatory cytokines IL-18 and IL-1beta in the mechanism of bleomycin sulfate –induced human and mouse lung injury [3].

General tips
We do not recommend long-term storage for the solution, please use it up soon.
Protocol
Cell experiment [1]:
Cell lines
ADIPO-P2 cells
Preparation method
The solubility of this compound in DMSO is >10 mM. General tips for obtaining a higher concentration: Please warm the tube at 37 °C for 10 minutes and/or shake it in the ultrasonic bath for a while. Stock solution can be stored below -20 °C for several months.
Reaction Conditions
2.5 μg/mL; 30 mins
Applications
In ADIPO-P2 cells, Bleomycin Sulfate showed significant clastogenic effect, which even lasted for at least 10 days after exposure.
Animal experiment [2]:
Animal models
CD-1 mice
Dosage form
5 mg/kg, 2 ml/kg, intratracheally
Applications
Bleomycin Sulfate promoted the development of inflammation, resulting in severe pulmonary fibrosis, as well as simultaneous increasing of TGF-β1, Smad3 and STAT1.
Other notes
Please test the solubility of all compounds indoor, and the actual solubility may slightly differ with the theoretical value. This is caused by an experimental system error and it is normal.
