LL-37 is a synthetic peptide corresponding to the active domain of human cathelicidin antimicrobial peptide (hCAP-18), a component of the innate immune system found in neutrophils and epithelial cells. It is utilized in laboratory research to study antimicrobial mechanisms, immune modulation, and inflammatory response pathways. In vitro and preclinical studies explore its role in membrane disruption of pathogens, cytokine regulation, and host defense processes under controlled experimental conditions.

Ongoing investigations assess LL-37’s potential applications in immunology, wound-healing models, infection studies, and anti-inflammatory research. All work is conducted within laboratory environments for research purposes only.

Important Notice: This product is intended strictly for research purposes only. It is not approved by the FDA and is not intended for human or animal consumption, nor for diagnostic, therapeutic, or clinical applications. Usage of LL-37 outside laboratory research settings violates sections 505(a) and 301(d) of the Federal Food, Drug, and Cosmetic Act (FD&C Act), 21 U.S.C. §§ 355(a) and 331(d).
