Mechanism of Action & Biochemical Context

LL-37 is the only human cathelicidin antimicrobial peptide (CAMP). Produced by immune cells, it exhibits broad-spectrum bactericidal activity and plays a critical role in wound healing, immune signaling, and combating chronic biofilm infections.

Storage, Reconstitution & Stability Guidelines

Prior to reconstitution, lyophilized LL-37 powder should be stored away from light between 2°C and 8°C for short-term access, or -20°C for long-term preservation. Once reconstituted with Bacteriostatic Water (0.9% benzyl alcohol preservative), maintain strict refrigeration between 2°C and 8°C. Do not freeze liquid solution.
