LL-37 5 mg – Human Antimicrobial Peptide for Immunological and Cellular Research

LL-37 is a human-derived antimicrobial peptide belonging to the cathelicidin family. It is the only known human cathelicidin capable of broad-spectrum activity and is widely used in laboratory environments to study innate immunity, cellular defense mechanisms, wound-healing pathways, and microbial interaction models. LL-37 is of particular interest in research focused on epithelial barrier function, immunomodulation, and host–pathogen dynamics.

Each vial contains 5 mg of high-purity LL-37 produced under GMP-compliant laboratory conditions and sealed in tamper-evident packaging to ensure analytical integrity. Researchers in Colombia rely on Poly Biotech for consistent access to advanced antimicrobial peptides for controlled studies in immunology and cellular biology.
