Reconstitution Centrifuge the vial before adding solvent (10,000 x g for 5 minutes) to spin down all the powder to the bottom of the vial. The lyophilized product may be difficult to visualize. Add solvent directly to the centrifuged vial. Tap the vial to aid in dissolving the lyophilized product. Tilt and gently roll the liquid over the walls of the vial. Avoid vigorous vortexing. Light vortexing for up to 3 seconds is acceptable if needed. For long-term storage in solution, we recommend preparing a stock solution by dissolving the product in sterile water at a concentration of at least 0.1 mg/mL. Divide the stock solution into small aliquots and store at -20°C. Before use, thaw the relevant vial(s) and dilute to the desired working concentration in your working buffer. It is recommended to prepare fresh solutions in working buffers just before use. Repeat freeze-thawing may result in loss of activity

Scientific background

BQ788 is a synthetic modified tripeptide that acts as a potent, selective and competitive antagonist of the ET-B (endothelin B) receptor, a receptor that belongs to the G-protein coupled receptor (GPCR) superfamily. BQ788 is a soluble compound that does not bind plasma proteins and is metabolized in a short period of time. It lacks oral bioavailability and requires intra-arterial administration. The compound is used in vitro and in vivo to demonstrate the role of endogenous and exogenous endothelin receptor subtypes in physiological and pathophysiological conditions1,2. It displays IC50 values of 1.2 nM in radiolabeled Girardi heart cells and 1300 nM in human neuroblastoma cell line, respectively1.ET-A and ET-B receptors are widely distributed in vascular tissues where they mediate vasoconstriction and in nonvascular tissues such as the liver, kidney, and brain. ET-A receptors have high affinity for ET-1 and ET-2 peptides and relatively low affinity for ET-3, while ET-B receptors show high affinity for all ET isopeptides1.
