LL-37 vs Phosphate Buffered Saline
A side-by-side research comparison of LL-37 and Phosphate Buffered Saline across mechanism, dosing, half-life, benefits, side effects and research status.
Comparison table
| Attribute | LL-37 | Phosphate Buffered Saline |
|---|---|---|
| Full name | Cathelicidin Antimicrobial Peptide LL-37 | Phosphate Buffered Saline (PBS) |
| Category | Healing & Recovery | Healing & Recovery |
| Status | Research compound | Buffer solvent |
| Mechanism | Disrupts microbial membranes, neutralizes endotoxins, recruits immune cells via chemotaxis, and promotes angiogenesis and re-epithelialization. | The phosphate buffer maintains a stable, near-physiological pH (~7.4) while the saline provides isotonic conditions, protecting peptides and proteins from pH-driven degradation during dissolution and handling. |
| Molecular weight | 4493.33 Da | Buffered salt solution |
| Half-life | ~4-6 hours | N/A (solvent) |
| Bioavailability | Variable by route; topical and injectable | N/A (diluent) |
| Typical dose | 50-100 mcg | Volume to reach target concentration |
| Frequency | Daily | As needed to reconstitute |
| Route | Topical or subcutaneous injection | Added to peptide/protein vial |
LL-37 reported benefits
- Broad-spectrum antimicrobial
- Wound healing acceleration
- Biofilm disruption
