Key Product Details
Description
Highly potent KCa2 (SK) channel blocker
Product Description
UCL 1684 is a highly potent, non-peptidic blocker of the apamin-sensitive Ca2+-activated K+ channel (KCa2.1) (IC50 = 3 nM in rat sympathetic neurons). Blocks hKCa2.1 and rKCa2.2 channels expressed in HEK 293 cells with IC50 values of 762 and 364 pM respectively.Licensing Information
