The assay being used is called PubChem BioAssay qHTS, which is a method for identifying potential inhibitors of the Phosphatase Activity of Eya2. In this assay, a Carboxyl-terminal binding protein (CtBP) Counterscreen is used to validate the results obtained from the initial screening process. This type of assay falls under the category of confirmatory assays, which is widely used to confirm the results obtained from other assays. Additionally, the assay type description for this test is classified as binding, meaning it measures the binding activity of various compounds in the test sample. Can this molecule be deemed as efficacious for this assay?
