Overview
Tissue-repair peptides are investigated for their roles in angiogenesis, fibroblast activity, extracellular matrix remodeling, and inflammation resolution. Many derive from naturally-occurring fragments of larger repair proteins.
LL-37 is studied for its activity at Antimicrobial / FPR2, with a reported half-life of ~1 hr. The compound is supplied as a lyophilized powder and reconstituted with bac water prior to use in laboratory research.
Mechanism of Action
VEGF / NO signaling, actin polymerization, and downregulation of pro-inflammatory transcription factors.
In published in-vitro work, LL-37 engages Antimicrobial alongside related receptor subtypes to initiate downstream signaling. The reported half-life of ~1 hr informs typical dosing intervals in experimental protocols.
Research Applications
- Wound healing and cell migration assays
- Tendon and ligament repair models
- Angiogenesis (HUVEC, CAM) experiments
- NF-κB and cytokine modulation studies
Handling & Reconstitution
Reference guidance for laboratory handling.
- Storage: -20°C lyophilized. Avoid repeated freeze-thaw cycles.
- Reconstitution: BAC water. Add diluent slowly down the side of the vial; gentle swirl, do not shake.
- Stability: Once reconstituted, store at 2–8°C and use within 14–28 days depending on peptide stability.
- Working solution: Calculate target concentration before reconstitution. Our calculator can help.
Quality & Verification
- Every batch of LL-37 we ship is third-party tested by an ISO-accredited lab. Each order arrives with a batch-matched Certificate of Analysis showing HPLC purity (≥99%), mass spectrometry confirmation of 4493.3 Da, and endotoxin / bioburden screening where applicable.
