The synthetic LL-37 is a lab-made version of the human antimicrobial peptide LL-37. It is manufactured to replicate the natural amino-acid sequence of the endogenous peptide derived from CAP-18.
LL-37 is the active peptide fragment that is generated when CAP-18 is enzymatically cleaved. Furthermore, studies indicate that LL-37 is derived from the C-terminal portion of CAP-18 and contains 37 amino acids.
In modern research settings,LL-37 is being studied for its role in innate immune responses and antimicrobial mechanisms in preclinical models. Researchers also investigate this peptide for its potential involvement in inflammatory signaling and tissue-related processes in preclinical models.
Note:LL-37 is not approved by the U.S. Food and Drug Administration for any therapeutic use. It is primarily recognized as a research peptide. We sell it only for lab research purposes. It is not intended for human or animal use.
