LL-37 Research Reference

LL-37 is an antimicrobial host-defense peptide researched for innate immune signaling, bacterial-membrane interaction, wound-healing biology, and inflammatory pathway modulation. It requires formulation caution due to sensitivity and irritation potential. LL-37 is catalogued in the Recovery / Regenerative group of this reference and is studied in laboratory and in-vitro models only.

Reference half-life for LL-37: short acting. Human pharmacokinetics are not standardized. Treat exposure as short acting unless compound-specific data or formal formulation labeling indicates otherwise. Published pharmacokinetic figures come from research and clinical-literature contexts and are listed here as reference values for laboratory work only, not as guidance for any person or animal.

Use solvent appropriate to formulation. Refrigerate after reconstitution, protect from heat/light, and avoid repeated temperature cycling. Lyophilized research peptides are generally kept cold, dry, and away from light, and reconstituted solutions are labeled with concentration and date. Follow the storage conditions documented for the specific lot you receive.

The reference reconstitution for the 5 mg vial is 2 mL sterile AA water or DMSO-compatible solvent depending on formulation; verify compatibility, which gives a concentration of about 2.5 mg/mL. Concentration equals peptide mass divided by diluent volume, so adding more liquid lowers the concentration. Add diluent slowly down the vial wall, swirl rather than shake, and confirm the arithmetic before preparing any research solution.

No. The research-grade LL-37 described here is an investigational, research-use-only material and is not an FDA-approved drug product. Where an approved pharmaceutical form of a compound exists, it is a separate prescription product. This reference is not medical advice, and the material is not for human or animal consumption.
