Polymyxin B2
Based on 1 Customer Validation
Polymyxin B2 is a polypeptide antibiotic with particularly potent antibacterial activity against Gram-negative bacteria. Polymyxin B2 kills bacteria by binding to lipopolysaccharide molecules on the bacterial cell membrane, disrupting membrane integrity and causing leakage of intracellular contents. Polymyxin B2 is used in studies related to Pseudomonas aeruginosa infection and acute enteritis.
