Product Overview

LL-37 is a naturally occurring antimicrobial peptide (AMP) belonging to the cathelicidin family and is an important component of the innate immune system. It has become an increasingly studied research compound due to its broad range of biological activities involving immune signaling, tissue regeneration, inflammation, and host defense mechanisms.

This product is supplied as a lyophilized (freeze-dried) powder and is intended strictly for laboratory and research purposes.

Research Profile

LL-37 is the only human cathelicidin peptide identified to date and is naturally produced by neutrophils, macrophages, epithelial cells, and other immune tissues. In research settings, LL-37 has demonstrated antimicrobial, antiviral, antifungal, and immunomodulatory properties while also influencing wound healing and cellular communication.

Rather than functioning solely as an antimicrobial agent, LL-37 is recognized for its ability to regulate immune responses, recruit immune cells, promote angiogenesis, and support tissue remodeling. These diverse mechanisms continue to make it an area of active scientific investigation.
