Ranalexin CAS 155761-99-2

Product Overview

Ranalexin (CAS 155761-99-2) is an antimicrobial peptide originally isolated from the skin of the bullfrog Rana catesbeiana. Structurally related to polymyxin antibiotics, it features a heptapeptide ring stabilized by an intramolecular disulfide bridge. In biochemical and microbiological research, Ranalexin serves as a valuable model compound for studying membrane disruption kinetics, bacterial cell envelope permeability, synergistic antimicrobial interactions, and peptide-lipid membrane binding dynamics. As a top professional peptide manufacturer in China, Conscientia Industrial produces Ranalexin via advanced solid-phase peptide synthesis (SPPS), ensuring accurate molecular sequence, reproducible quality, and exceptionally high purity.
