WitrynaWith more than 80 distinct potassium ion channel isoforms, the fluorescent signal reported in this assay serves as a surrogate readout of the activity of any ion channel or transporter that is permeant to thallium, including hERG, Kv1.3, Kir2.1, KATP, and many other of >80 distinct potassium ion channel gene products. WitrynaThe hERG IC50:Cmax ratio was correlated with TdP incidence for culprit drugs. This validation provides support for the potential use of the hERG IC50:Cmax ratio for clinical decision making in instances of drug selection where TdP risk is a concern.
