This Thermo Scientific Chemicals brand product was originally part of the Acros Organics product portfolio. Some documentation and label information may refer to the legacy brand. The original Acros Organics product / item code or SKU reference has not changed as a part of the brand transition to Thermo Scientific Chemicals.
General description
• Colistin Sulfate salt is a stable, cationic, water-soluble, white powder composed of over 30 components
• 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
• This compound is often used in the management of multi-drug resistant Gram-negative infections
