Brief Introduction:

LL37 is a synthetic cathelicidin-derived antimicrobial peptide exclusively for laboratory research. As the only human cathelicidin active peptide, it possesses broad-spectrum antibacterial, antifungal and antiviral biological activity. It effectively regulates immune cell activation, inhibits excessive inflammatory responses, and promotes skin barrier repair and mucosal tissue regeneration. With dual functions of antimicrobial defense and immune modulation, it is widely applied in microbial resistance research, inflammatory regulation, skin barrier repair and innate immune mechanism research.

Main Research Applications:

Broad-spectrum antimicrobial research: Used in cell and microbial models to study antibacterial, antifungal and antiviral activity mechanisms. Innate immune regulation research: Suitable for exploring immune cell recruitment, activation and innate defense pathway modulation. Anti-inflammatory tissue repair research: Applied to investigate inflammatory response inhibition and epidermal & mucosal barrier reconstruction. Skin regeneration research: For comparative analysis of wound healing, tissue remodeling and skin microenvironment improvement.

Immune defense mechanism research: Study host antimicrobial resistance and immune homeostasis regulatory characteristics.
