生理活性の詳細Type III antiarrhythmic drug that blocks ion channels encoded by the ether-a-go-go related gene (ERG1 or KCNH1). Blocks channels in the open configuration with little effect on the channels in the closed configuration. The IC50 for block of human ERG channels in expression systems is approx. 350 nM.
保存方法Store at +4°C. Store under Desiccating conditions. The product can be stored for up to 12 months.
溶解性Soluble in water to 100 mM
Wherever possible, you should prepare and use solutions on the same day. However, if you need to make up stock solutions in advance, we recommend that you store the solution as aliquots in tightly sealed vials at -20°C. Generally, these will be useable for up to one month. Before use, and prior to opening the vial we recommend that you allow your product to equilibrate to room temperature for at least 1 hour.
