SLIGRL-NH2 (Protease-Activated Receptor-2 Activating Peptide) is an agonist of Protease-Activated Receptor-2 (PAR-2)[1].

IC50 & Target


In Vitro

SLIGRL-NH2 is an agonist of PAR-2 and MrgprC11[1]. SLIGRL-NH2 causes an L-NAME-inhibited relaxation. Based on SLIGRL-NH2 causing a concentration-dependent relaxation with an EC50 of 10 µM in endothelium-free preparations in the presence of perivascular adipose tissue (PVAT) , 20 µM is used as a suitable ‘test’ concentration of peptide in subsequent experiments designed to evaluate the effects of potential inhibitors of ADRF release/action. In the endothelium-free aorta preparations, SLIGRL-NH2 causes a concentration-dependent relaxation in preparations only in the presence of PVAT [+PVAT, -ENDO (endothelium)][2].

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
