HS Code: 2941.90.00
Grade: Research / Laboratory Grade
Form: Powder

Product Overview

Colistin Sulfate is a polypeptide antibiotic belonging to the polymyxin class, widely used in microbiology, antimicrobial resistance research, and susceptibility testing. It exhibits potent activity against Gram-negative bacteria, particularly strains resistant to multiple other antibiotic classes.

In laboratory and research settings, Colistin Sulfate is commonly employed as a reference compound for studying cell membrane disruption, antibiotic resistance mechanisms, and in-vitro antimicrobial susceptibility testing.

Ausamics supplies high-purity Colistin Sulfate Powder suitable for controlled laboratory and in-vitro research applications, with consistent quality and batch traceability.

Scientific Background (Non-Clinical)

Colistin acts by binding to lipopolysaccharides (LPS) in the outer membrane of Gram-negative bacteria, disrupting membrane integrity and increasing permeability. This mechanism makes it a valuable research tool for:

• Studying membrane-active antibiotics

• Investigating multidrug-resistant (MDR) Gram-negative organisms

• Evaluating resistance development and adaptive responses

While colistin has historical and clinical relevance as a last-line antibiotic, this product is supplied strictly for research use only.
