Polymyxin B nonapeptide TFA

Polymyxin B nonapeptide TFA contains a truncated peptide core that mirrors key structural features of the parent cyclic lipopeptide. Its cationic residues support analysis of membrane interactions and charge-dependent binding. The trifluoroacetate form improves solubility and experimental consistency. Research spans antimicrobial peptide modeling, lipid-peptide interactions, and sequence-activity correlation studies.

Designed for biological research and industrial applications, not intended for individual clinical or medical purposes.
