A-278637

A-278637 is a selective KATP channel opening agent with an EC₅₀ of 102 nM. A-278637 does not interact with other ion channels, including L-type calcium channels or other neurotransmitter receptor systems. A-278637 possesses a greater functional selectivity for urinary bladder versus vascular smooth muscle in vivo. A-278637 can be used for the study of overactive bladder.

Help & FAQs

How should lyophilized recombinant proteins be reconstituted and stored?

1. Before opening the cap, centrifuge the vial at 13000 rpm for 20-30 seconds. This step will ensure that any lyophilized powder that may have adhered to the cap or walls is collected at the bottom of the vial, minimizing the risk of product loss.
