KPV, LL-37, Thymalin, Thymosin α1, ARA-290. Immune-modulation, antimicrobial, and anti-inflammatory research peptides.
Who sources this class & for what
Buyers in this category are research labs studying immune-modulation, cytokine signalling, and antimicrobial activity. The defining QC requirement is bacterial-endotoxin control: many downstream assays (NF-κB reporters, macrophage-activation panels, neutrophil-priming readouts) are themselves activated by endotoxin contamination, so a clean LAL on the specific lot is a precondition rather than a nice-to-have. LL-37 and related cationic antimicrobial peptides additionally benefit from low-bind plasticware during dilution.
