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. The product is soluble in pure water at high micromolar concentrations (100 µM - 1 mM). For long-term storage in solution, we recommend preparing a stock solution by dissolving the product in double-distilled water (ddH2O) at a concentration between 100-1000x of the final working concentration. 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. Centrifuge all product preparations before use. It is recommended to prepare fresh solutions in working buffers just before use. Avoid multiple freeze-thaw cycles to maintain biological activity

  • Activity: (±)-Bay K8644 is a dihydropyridine that acts as an L-type, voltage-gated Ca2+ channel agonist. The (-)-enantiomer has strong Ca2+ channel agonist properties, whereas the (+)-enantiomer has weak Ca2+ channel antagonist activity. The net activity of the racemic mix is L-type channel opening. In the presence of this agonist, channels tend to open for longer periods causing a large increase in the channel microscopic response1-4. (±)-Bay K8644 is also an inhibitor (by increasing the inactivation) of a Shaker KV channel5.

Scientific background

(±)-Bay K8644 is an opener of all L-type channels (CaV1 family). In the presence of this agonist, channels tend to open for longer periods causing a large increase in the channel macroscopic response.The net activity of the racemic mix is that of the (-)-enantiomer agonistic activity.(±)-Bay K8644 is a widely used L-type Ca2+ channel activator in various neuronal, muscle, endocrine, thyroid and other cell types.1-3
