LL37 is the only human-derived Cathelicidin antimicrobial peptide, serving as a core research reagent in microbial immune regulation, skin microenvironment homeostasis and cellular immune mechanism studies. With natural biocompatibility, stable molecular structure and specific activity, it avoids drug resistance risks and is widely applied in basic mechanism research of immunobiology, skin repair and microflora balance, becoming a popular experimental material for biomedicine and skincare research.

In preclinical research models, LL37 exhibits diverse physiological regulatory functions. It corely regulates microbial community homeostasis and inhibits the proliferation of harmful microorganisms, supporting research on mucosal and epidermal microecological balance. Meanwhile, it modulates innate immune responses, balances local immune factor expression and improves microenvironment immune disorders, providing reliable support for immune homeostasis research. In addition, LL37 regulates epidermal cell proliferation, migration and differentiation, participating in tissue repair and skin barrier reconstruction to facilitate exploration of epidermal maintenance mechanisms.

Verified by numerous preclinical studies, LL37 features stable bioactivity and high experimental repeatability with controllable variables. It is suitable for cell culture, microbial model construction, immune mechanism verification and long-term observation experiments, adapting to diverse scientific research systems.

Supplied as HPLC-purified lyophilized powder with low impurities, excellent water solubility and stable physicochemical properties. For research use only. Not for clinical application, oral use in

humans and animals, and has no therapeutic effect.
