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.

Components

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.

Caution

This product should be stored at 2-8°C.

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
