Mfr.No.	B-352, B-352_1 mg, B-352_10 mg, B-352_100 mg, B-352_25 mg, B-352_5 mg, B-352_50 mg
Description	(R)(+)-Bay K8644 (#B-352) is a highly pure, synthetic, and biologically active compound.
Molecular Formula	C16H15 F3N2O4.
Background	L-type Ca2+ channels possess binding sites for at least three distinct organic drug types: dihydropyridines (DHP), phenylalkylamines (PAA), and benzothiazepines (BTZ). These binding sites are known to reside in the alpha1 subunit of the channel.(R)(+)-Bay K8644 is a DHP L-type Ca2+-channel blocker with negative inotropic and vasodilatatory effects in vivo. (R)(+)-Bay K8644 shows opposite effects to (S)(-)-Bay K8644. The action of the of (R)(+)-Bay K8644 was studied in rat tail artery and guinea pig ileal longitudinal smooth muscle using pharmacologic and radioligand binding assays. (R)(+)-Bay K8644 inhibited the responses to KCI-induced depolarization with IC50 values of 16.1-25.6 nM1.
Shipping	Shipped at room temperature. Product as supplied can be stored intact at room temperature for several weeks. For longer periods, it should be stored at -20°C
Concentration	1-100 uM.
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

Form	Lyophilized powder.
Storage	Storage After Reconstitution: The reconstituted solution can be stored at 4°C for up to 1 week. For longer periods (up to 6 months), small aliquots should be stored at -20°C. We do not recommend storing the product in working solutions for longer than a few days. Avoid multiple freeze-thaw cycles. Storage before Reconstitution: The product is shipped as a lyophilized powder at room temperature. Upon receipt, store the product at -20°C. Protect from moisture. Storage of solutions: Up to four weeks at 4°C or three months at -20°C.
