Ion Channel Binding Assays

Creative Biogene is the leading company offering the first-class ion channel binding assay services. As a pioneer in this field, based on years of research experience, Creative Biogene provides services to detect the binding affinity of a compound to your target ion channel.

Creative Biogene utilizes the gold standard filtration method to perform the highest assay robustness. We offer radioligand binding assays across a wide range of ion channel families, including sodium, potassium, and calcium, and so on. By radioligand displacement assays, Creative Biogene can help you determine the interaction and calculate a compound's affinity for a channel of interest.

High-throughput ion channel binding assays have been configured for filter binding assays, scintillation proximity assays, and fluorescence polarization assays. Ligand binding assays can detect compounds that compete with ligands for binding to a specific site. Given its low cost and high throughput, binding assays have been developed for many voltage-gated and ligand-gated ion channels. Ligand binding assays require previous information of the target binding sites and the formation of a radioligand which is specific to those binding sites. Activity of the interest compound is indicated by the displacement of the labeled ligand (Haibo, et al. 2016).

Consequently, conventional instrumentation can be used, in which throughput represents its major strength. Because the method only discovers compounds affecting radioligand binding, it misses allosteric modulators of ion channels. Binding assays identify affinity data but cannot identify the functional change of ion channels. Therefore, by combining with functional assays, Creative Biogene offers ion channel binding studies that can provide an orthogonal approach to creating a full profile of your compound's in vitro pharmacology.
