Creative Biogene is the leading company offering unmatched expertise and experience in kinase drug discovery. Our talent scientists provide the highest quality results efficiently with the most competitive price. Based on years of know-how in this field, Creative Biogene offers you best service in kinase biochemical assays.
Creative Biogene offers filter-binding radiometric kinase activity assay, which has long been established as the most reliable, robust and gold standard assay against all other assay formats. We can also provide TR-FRET technology to measure substrate phosphorylation when a greater level of throughput is desired to support high throughput screens. Other assay formats, including Caliper, Luminescence, LC-MS, IMAP, ADP-Quest, etc, are also available in Creative Biogene.
Radiometric based assays are the most reliable and stable methods for detecting kinase reactions; therefore, they are the preferred method for kinase profiling assay. Compared with those nonradiometric methods, it is considered the radiometric based filtration binding assay as the ‘gold standard’ method. In this assay format, the kinase reaction is carried out in the presence of 32P-γ-ATP or 33P-γ-ATP. By binding of the final radioisotope labeled products to filters, unreacted phosphate can be washed away without interfering with the detection of real phosphorylated products (Haiching, et al. 2008). In addition, scintillation proximity assay (SPA) is also used in radiometric kinase activity test.
The FRET assay is a kind of technology that is amenable to automation. This assay uses ‘donor’ and ‘acceptor’ fluorophores in proximity, with the excited donor fluorophore exhibiting nonradiative energy transfer to an acceptor fluorophore (Haiching, et al. 2008).

Our service development comprises routine assay optimization (including enzyme titration, time course, Km determination etc.) and assay validation (such as DMSO tolerance, Z' test, compound validation, etc.). In addition, Creative Biogene also offers service for compound MOA research in the effort to further characterize the identified compounds.
