LL37
Preclinical — Animal / cell-model data onlyWhat it is
A human antimicrobial peptide (cathelicidin fragment) studied for antimicrobial and wound-healing activity, mostly in the lab.
LL-37 is a fragment of the human host-defence protein cathelicidin, studied for antimicrobial and wound-healing activity — mostly in the lab. It can be pro-inflammatory at higher concentrations.
Research context
Studied in relation to:
- Antimicrobial research
- Wound-healing research
Points in its favour in the literature:
- Naturally occurring host-defence peptide
- Broad research interest
Caveats and unknowns:
- Can be pro-inflammatory at some concentrations
- Human therapeutic data limited
- Unlicensed for human use
Handling & reference data
Route in published researchSubcutaneous injection is the route most commonly described in the research literature. or local, in research.
Published clinical / research context (not instructions)No well-established research dose; small microgram amounts are used in laboratory studies.
Storage (lyophilised)Lyophilised (freeze-dried) powder: refrigerate at 2–8 °C short-term, or freeze at −20 °C or below for long-term storage. Keep sealed and out of light.
Reconstituted solutionOnce reconstituted: keep refrigerated (2–8 °C), protect from light, do not freeze. With bacteriostatic water, commonly used within ~4 weeks; with plain sterile water, within ~24–48 h.
Worked reconstitution example (arithmetic only)e.g. 5 mg vial + 2 mL → 2.5 mg/mL.
