Overview
LL-37 (Human Cathelicidin Antimicrobial Peptide) is a 37-amino acid peptide derived from the C-terminal domain of the human cathelicidin protein hCAP18, encoded by the CAMP gene. As the only known member of the human cathelicidin family, LL-37 is recognized as a key effector molecule in innate immune defense, with extensive research interest in its broad-spectrum antimicrobial activity, immunomodulatory signaling, and wound-healing cascades. Its amphipathic α-helical structure enables membrane disruption in target organisms, making it a valuable tool in laboratory studies of host defense peptides, biofilm inhibition, and inflammation regulation.

Reconstitution & Storage
Reconstitution calculator
Enter your vial, bacteriostatic water, and target dose — we’ll compute units on a standard U-100 insulin syringe, volume per dose, and doses per vial. Research reference only.
Reference only. Not dosing guidance. Values round to the nearest 0.1 unit / 0.01 ml.
- Uncap the vial. Wipe the rubber stopper with an alcohol swab and allow it to air-dry.
- Draw bacteriostatic water to your target concentration using the calculator above.
- Inject slowly down the side. Avoid direct streams onto the lyophilized powder. Do not shake — swirl gently until fully dissolved.
- Label the vial with the concentration and reconstitution date.
