Colistin Sodium Methanesulfonate

Product Description

Colistin is a polymyxin antibiotic effective against gram-negative bacteria. It has been used to permeabilize bacterial cell membranes and to study mannose-resistant haemagglutination. It has also been implicated in researching effective treatment for P. aeruginosa infections.

Colistin functions by targeting cell membranes and altering their permeability. Colistin sodium methanesulfonate (CMS) is considered an inactive prodrug, which means it is inactive until converted into colistin by cellular enzymes. GoldBio also offers Colistin sulfate (colistin), the end product of CMS, which does not require molecular conversion for antimicrobial properties.

Antibiotics are often used in clinical in vitro tests known as antimicrobial susceptibility tests or ASTs to determine their efficacy against certain bacterial species. They are tested against gram-negative and gram-positive bacteria using panels, discs, and MIC strips by medical microbiologists. ASTs decrease the risk of using an antibiotic against bacteria exhibiting resistance to it, and the results are used in clinical settings to determine which antibiotic(s) to prescribe for various infections.
