LL-37 – 5 mg Vial

CAS Number: 154947-66-7
Molecular Formula: C205H340N60O53
Molecular Weight: ~4493.37 g/mol
Sequence: LLGDFFRKSKEKIGKEFKRIVQRIKDFLRNLVPRTES
Synonyms: Human Cathelicidin LL-37, hCAP-18 Fragment

Description:
LL-37 is a cationic antimicrobial peptide consisting of 37 amino acids, derived from the C-terminal region of the human cathelicidin precursor hCAP-18. It plays a crucial role in the innate immune system, exhibiting broad-spectrum antimicrobial activity against gram-positive and gram-negative bacteria, fungi, and certain viruses.

In research models, LL-37 has been studied for its ability to modulate inflammation, promote wound healing, and influence immune signaling pathways through direct interaction with microbial membranes and host cell receptors. Its amphipathic structure allows it to integrate into lipid bilayers, contributing to both antimicrobial defense and tissue regeneration responses.
