    Product Description

    NS 19504 is an activator of large-conductance calcium-activated potassium channels (KCa1.1/BK).1 It induces currents in whole-cell patch-clamp assays using HEK293 cells expressing human KCa1.1/BK when used at a concentration of 10 µM. NS 19504 decreases the force of spontaneous phasic contractions in isolated and perfused guinea pig bladder smooth muscle strips (EC50 = 640 nM). It inhibits methoxamine-induced contractions in isolated rat saphenous arteries when used at a concentration of 6 µM.2

    WARNING This product is not for human or veterinary use.
