Cav1.2 on Qube 384

Schupp, Melanie



The voltage-sensitive L-type Ca2+-channel (LTCC) CaV1.2 is a crucial component for controlling intracellular activity and thereby essential in the cardiovascular and neuronal system. It is widely expressed in vascular smooth muscle tissue and the heart muscle. The opening of the channels leads to an increase of intracellular calcium, which act as second messenger, and thereby affects a variety of cellular processes including heart muscle contraction and CaV1.2 is therefore an important target in e.g. safety pharmacology screening. CaV1.2 channels are known to require a large depolarization for their activation and once activated they display a long-lasting current flow, which typically can be blocked by low micromolar concentrations of e.g. dihydropyridines, phenylalkylamines and benzothiazepines. In these studies, currents from HEK-hCaV1.2 were recorded on the high-throughput platform Qube 384 in both single-hole and multi-hole mode. Success rates, IV characteristics and the pharmacological effects of three different compounds were determined.
