摘要
The bee venom toxin apamin is an important drug tool for characterising small conductance Ca2+-activated K+ channels (SK channels). In recombinant expression systems both rSK2 and rSK3 channels are potently blocked by apamin, whilst the sensitivity of SK1 channels is somewhat less clear. In the present study we have conducted a detailed analysis by patch clamp electrophysiology of the effects of apamin on human SK channels (SK1, SK2 and SK3) stably expressed in Chinese hamster ovary (CHO-K1) cells.
