Human Cathelicidin Antimicrobial Peptide LL-37 (LL-37 Peptide Powder) is the only human-derived Cathelicidin antimicrobial peptide, consisting of 37 amino acids. It is an active fragment derived from the precursor protein hCAP-18, encoded by the CAMP gene and activated by proteinase 3. Widely present in neutrophils, epithelial cells, and mucosal tissues, LL-37 Peptide Powder is an essential component of the human innate immune system.

Prepared using solid-phase peptide synthesis, the molecular sequence is identical to endogenous LL-37, forming an amphipathic α-helical conformation. The powder is high-purity, low in impurities, and biologically stable, free from animal-derived contaminants. It is ideal for buyers seeking high-purity, cost-effective bulk procurement. Its dual features-broad-spectrum antimicrobial activity and immune modulation-are backed by extensive scientific data, making it suitable for antimicrobial, immune regulation, and wound repair applications, as well as overseas research experiments, formulation development, and functional product R&D. This effectively addresses limitations of traditional antibiotics, including resistance and narrow antimicrobial spectrum.

LL-37 Peptide Powder is an endogenous antimicrobial peptide. Its amphipathic α-helical structure allows selective binding to negatively charged pathogen membranes while sparing neutral human cells, enhancing safety over traditional antibiotics.

● Antimicrobial Mechanism – Electrostatic binding, oligomerization, pore formation, membrane disruption, leakage of intracellular contents.         Inhibits protein synthesis and genome integrity. Low risk of resistance, suitable for long-term research.

● Immune Modulation – Binds FPRL1 on immune cells, recruits immune cells, promotes interferon and interleukin secretion, neutralizes LPS, suppresses excessive pro-inflammatory factors, maintaining homeostasis.

● Biofilm & Wound Repair – Disrupts biofilms, activates cell proliferation and migration, promotes angiogenesis. Neuroprotective and antioxidant effects enhance multifunctional applications, ideal for bulk Chinese procurement of LL-37 Peptide Powder.
