G protein-coupled receptors (GPCRs), or seven transmembrane receptors (7TMs), are the largest family of cell-surface molecules involved in signal transduction. GPCRs have drawn much attention for treating hypertension, neurological, pain and other disorders, as more than 40% of the clinically marketed drugs are targeting GPCRs.

GPCR drug screening is essentially based on testing available molecule libraries. Such libraries can contain thousands of different compounds derived either by natural sampling, random synthesis or both, which are tested for their ability to bind to or interfere with the function of a GPCR molecule. Given the large number of molecules in those libraries, the use of high-throughput screening technologies that enable rapid testing through miniaturization and parallelization is indispensable. Creative Bioarray offers a comprehensive selection of binding and functional GPCR assays to meet the GPCR drug discovery research needs of both chemists and biologists. As a pioneer in this field, we can save your time and cost of the discovery programs by taking advantage of our expertise and innovative technology platforms.

So far, Creative Bioarray has successfully constructed GPCR over-expressing stable cell lines of various species, which has become one of the world's largest banks of GPCR cells. These cell lines have been verified in the functionality and stability through reporter gene assay or intracellular calcium assay, to satisfy our customers' requirements for screening GPCR-target drugs and final evaluation.
