Is there a fluorescence alternative to the hERG channel patch clamp assay?
Therefore all new drugs have to be tested for interaction with the hERG channel. The classical way to test the hERG channel is with patch clamp studies, but this is time consuming and it requires specialized electrophysiological equipment.
Now there is a more cost-effective, faster alternative to the hERG patch clamp assay that is used to test drug-induced long Q-T syndrome. It is the Predictor® hERG cellular FP assay from Life Technologies. This fluorescence polarization application saves money and time by allowing potential drugs to be prescreened before undergoing more tedious patch clamp screening.
