LL-37 — Research Use Only LL-37 is a 37-amino-acid peptide released from the C-terminus of hCAP18, the only human cathelicidin, encoded by the CAMP gene. It is studied as a cationic, amphipathic host-defense peptide that adopts an alpha-helical structure in membrane-like environments. Laboratory and preclinical research has examined LL-37 in experimental models involving antimicrobial membrane interaction, lipopolysaccharide binding, innate-immune and inflammatory signaling, formyl-peptide-receptor activity, epithelial-barrier biology, and wound-repair pathways. Most available findings come from cell and animal studies and should not be interpreted as established human safety or therapeutic efficacy.

Lab Tested

Summary transcribed from the supplied lab report for this product.

Recreated LL-37 chromatogramApproximate visual recreation of the supplied report image, not raw instrument data. From zero to 13.5 minutes, the baseline rises broadly around five minutes then tapers. A narrow Surrogate peak at 6.586 minutes reaches about 480 mAU and the dominant sharp LL-37 peak at 9.590 minutes reaches about 1050 mAU. Smaller features appear around eight, 10.5, 11.3 and 12.8 minutes before the trace returns near 190 mAU.200400600800100002468101213.5minmAULL-37 · 9.590 minSurrogate · 6.586 min
