What is LL-37?
LL-37 is the 37-amino-acid active fragment of the human cathelicidin protein hCAP18. It is an amphipathic, alpha-helical host-defense peptide and a standard reference compound in antimicrobial-peptide research, where its membrane activity and its signaling effects on immune cells are studied in vitro.
Where it is used in the lab
- Minimum inhibitory concentration and membrane-disruption assays
- Biofilm models
- Immune-cell signaling studies
