LL-37 Lyophilized Powder – Vial – Research Use Only
LL-37 is a synthetic research peptide corresponding to the C-terminal fragment of human cathelicidin (hCAP-18), a naturally occurring antimicrobial peptide that plays a key role in the innate immune system. It is supplied as a lyophilized powder in a sealed research vial and is widely studied for its multifaceted biological activities.
In laboratory settings, researchers examine how LL-37 interacts with cell membranes, immune cells, and various signaling pathways. It is particularly noted for its ability to disrupt microbial membranes while also influencing host immune responses and tissue repair processes.
Researchers commonly study LL-37 to explore its potential involvement in:
- Antimicrobial activity against a broad range of bacteria, viruses, and fungi
- Innate immune system modulation and immune cell recruitment
- Wound healing, tissue regeneration, and epithelial repair mechanisms
- Anti-inflammatory and pro-inflammatory balance in different contexts
- Angiogenesis and promotion of new blood vessel formation
- Cell proliferation, migration, and survival signaling
- Gut barrier function and microbiome-related research
As a cathelicidin-derived peptide, LL-37 serves as an important tool for investigating host defense peptides, immune regulation, and regenerative processes in controlled laboratory environments.
