Description
Colistin Sulfate salt (2:5), CAS # 1264-72-8, (synonym: Polymyxin E Complex), is a complex mixture of antibiotics, with Colistin A and B being the primary components. It has anti-bacterial activity against Gram-positive and Gram-negative bacteria and may also be used as a neuromuscular blocker.
Colistin sulfate A Polymyxin potent antibiotic and apoptosis inducer. This compound induces apoptosis through interaction with the cytoplasmic membrane. Colistin is a key microbiological component in Colistin Oxolinic Acid Blood Agar utilized in the cultivation of Aminobacter aminovorans, Bacillus species, Hyphomicrobium species and Methylobacterium species. It is also a critical component is VCN Inhibitor & VCNT Inhibitor growth media used in the isolation of Neisseria species.

General description
n
• Colistin Sulfate salt is a stable, cationic, water-soluble, white powder composed of over 30 components
n
• Originally isolated from B. polymyxa, it inhibits the growth of the Gram-negative (e.g. E. coli, P. aeruginosa, P. fluorescens, and S. enterica), and Gram-positive bacteria (e.g. L. lactis, P. polymyxa, P. acidilactici, and S. aureus) by permeabilizing the bacterial cell membrane
Applications
• Colistin Sulfate has potent anti-endotoxin activity rendered through its ability to bind lippopolysaccharides that make up bacterial endotoxins
n
• This compound is often used in the management of multi-drug resistant Gram-negative infections
