PR1MA™ Phleomycin, Powder
CAS Number: 11006-33-0
Molecular Weight: 1525
Chemical Formula: C55H85O21N20S 2Cu • HCl
Solubility: Water
Storage Temp: 2-8°C
Produced by Streptomyces verticillus and part of the structurally related group of Bleomycin/Phleomycin type antibiotics. Used as a selective agent in transformation experiments with mammalian cells, plant cells, and yeast. Cytotoxic action of this type of antibiotic results from the ability to cause fragmentation of DNA. In Vitro studies indicate that Phleomycin causes the accumulation of cells in the G2 phase of the cell cycle.
