General description
Chemical structure: glycopeptide
Application
Bleomycin Sulfate is an antineoplastic antibiotic isolated from Streptomyces verticillus. It is recommended for use as a cell culture agent at 10-100 μg/mL.
Biochem/physiol Actions
Bleomycin sulfate binds to DNA, causes ssDNA scission at specific base sequences and inhibits DNA synthesis. This inhibitory action requires bleomycin to bind oxygen and a metal ion. It can also cleave RNA, to a lesser degree but more selectively. It acts as an inducer and regulator of apoptosis and inhibits tumor angiogenesis.
Preparation Note
The product is soluble in water in water at 20 mg/mL and is active for several days. A solution of 2 units/mL in 0.1 M neutral potassium phosphate should be used within 14 days. A solution is active for three months at 3 units/mL in normal saline.
Other Notes
Keep container tightly closed in a dry and well-ventilated place, strongly hygroscopic
This product is a mixture of glycopeptides antibiotics containing Bleomycin A2 (70%) and B2(30%). Bleomycins differ from each other in the terminal amine and show varying biological activity.
Disclaimer
This product should be stored at 2-8°C.
