Description

General description
Chemical structure: peptide
Application
Colistin sulfate is used to permeabilize bacterial cell membranes and to study mannose-resistant haemagglutination and antibiotic resistance in certain organisms such as A. baumannii . It has been used to study hephrotoxicity in the rat kidney , and MICs, time-kill kinetics, and postantibiotic effect (PAE) against Pseudomonas aeruginosa .
Biochem/physiol Actions
Mode of Action: Binds to lipids on the cell cytoplasmic membrane of Gram-negative bacteria and disrupts the cell wall integrity.
Antimicrobial spectrum: Gram-negative bacteria.
Mode of Action: Binds to lipids on the cell cytoplasmic membrane of Gram-negative bacteria and disrupts the cell wall integrity.
Antimicrobial spectrum: Gram-negative bacteria. It is proposed that renal reabsorption of colistin may involve organic cation transporters and peptide transporters and that the process is sensitive to pH .
Analysis Note
Freely soluble in water, practically insoluble in acetone and in ethanol (96%)
Other Notes
Keep container tightly closed in a dry and well-ventilated place.
