2. Product Description:
LL‑37 is the only human cathelicidin antimicrobial peptide, derived from the hCAP18 protein. It is a 37‑amino acid cationic, amphipathic α‑helical peptide with broad immunomodulatory and host defense functions.
CAS Number: 154947-66-7
It exhibits potent antimicrobial activity against Gram‑positive and Gram‑negative bacteria, fungi, and enveloped viruses. Beyond direct microbial killing, LL‑37 regulates inflammation, promotes wound healing, modulates immune cell recruitment, and supports tissue repair. It is widely studied in immunology, dermatology, infection research, and mucosal defense.
Production：
Manufactured via solid-phase peptide synthesis (SPPS), followed by purification and lyophilization to obtain the final product.
NOTE: This product was prepared by chemical synthesis. Used only for research. Not for human use.

7. peptides have obvious advantages:
Many active substances in the human body are in the form of peptides. Peptides are involved in various fields of human hormones, nerves, cell growth and reproduction, and their importance is to regulate the physiological functions of various systems and cells in the body, activate the relevant enzyme systems in the body, promote the permeability of intermediate metabolic membranes, or control DNA transcription or affect specific protein synthesis, and ultimately produce specific physiological effects. Peptides are important substances involved in various cell functions in human body. Peptides can be synthesized into cells and regulate their functional activities. Peptides act as neurotransmitters in the body, transmitting information. Peptides can be used as transportation tools in the human body to transport various nutrients and various vitamins, biotin, calcium and trace elements beneficial to the human body to the cells, organs and tissues of the human body. Peptide is an important physiological regulator of the human body, which can comprehensively regulate the physiological function of the human body, enhance and exert the physiological activity of the human body, and it has important biological functions
8.Main Functions & Benefits
Unlike conventional antibiotics, LL-37 acts on conserved membrane lipid components rather than specific microbial enzymes or ribosomes, making it a valuable model for studying mechanisms of antibiotic resistance avoidance and innate immune activation. Its dual role—simultaneous antimicrobial action and immunomodulatory signaling—allows researchers to investigate multicellular innate responses, epithelial barrier function, and peptide‑mediated modulation of TLR signaling and autophagy in a single system; it also demonstrates measurable activity in serum‑containing media at micromolar concentrations and is amenable to site‑directed analog design for structure–activity relationship studies.
