G-Protein Coupled Receptors (GPCR) represent a major research focus of many pharmaceutical and biotechnology companies in drug discovery. As a leading GPCR solution provider, HD Biosciences provides comprehensive assay development, high |
throughput screening and selectivity profiling services. |
|
All assays developed by HDB are HTS-compatible. Our cell lines that over-express GPCR are optimized with high S/N ratio measured by calcium, cAMP or reporter genes. In-house experience and know-how enable HDB to overcome cytotoxicity issues and generate stable GPCR cell lines, e.g. mGluRs and other targets. HDB’s extensive experience in the |
GPCR field provides clients the best in class experience and results. |
