Creative Biogene provides the best GPCR functional assay services. As a well-known expert in this field, our talented scientists with abundant experience and innovative techniques are confident in offering the highest quality services for your GPCR assays with the most competitive price.

Creative Biogene offers cell based assays covering multiple second messenger readouts, including GTPγS binding assays, cAMP assay, IP3/IP1 and Ca2+ assays, reporter assay, etc. In addition, we also offer receptor internalization assay, β-arrestin recruitment assay, label-free whole cell assay, and so on. The abundant experience in above assays enables us better understand compound activity and provide professional services. Our GPCR functional assays can evaluate the downstream effects of compounds against a broad range of GPCR targets. By combining with binding assays, Creative Biogene’s functional assays can provide a full profile of a compound's in vitro pharmacology.

It is important to understand compound on and off target activity, if we are evaluating a GPCR therapeutic's potential efficacy and liabilities. GPCRs can transmit signal through a variety of cascades, and a drug will activate, inhibit, or regulate one or more of these pathways.

Ligand-binding assays are useful to identify new compounds that target GPCRs. Further analysis of the biological responses after compound binding will help complete the whole picture concerning the overall characteristics of the compound. Upon ligand binding, GPCRs change their conformation and activate coupled G proteins, which subsequently promote second messenger production via downstream effectors. By GPCR functional assays, we can detect the activity of target GPCR, and may provide additional information on functional selectivity of candidate compounds.
