How to use

In Vitro:

SLIGRL-NH2 is an agonist of PAR-2 and MrgprC11. 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)].
