KMD Bioscience is an experienced provider of preclinical CRO services with a team of experts dedicated to providing our clients with a rapid, high-throughput drug target screening platform. We offer a wide range of compound library screening services to major research institutes and pharmaceutical companies. Clients simply provide us with their compound libraries and we screen potential compounds using standard experimental procedures.
G protein-coupled receptors (GPCRs) play an incredible role in a range of functions in the human body, and a better understanding of these receptors has greatly influenced modern medicine. Researchers estimate that between one-third and one-half of all marketed drugs work by binding to GPCRs.
GPCRs mediate many important physiological functions. The development and application of high-throughput GPCR assays are essential for early drug discovery, enabling cost-effective screening of large libraries of compounds to identify new drug candidates. Early functional GPCR assays relied primarily on the measurement of G protein-mediated second messengers. With the growing understanding of GPCR signaling, many G-protein independent pathways have been used to measure GPCR activity and can provide additional information on the functional selectivity of candidate compounds. Combined with an automated imaging system with label-free detection.
KMD Bioscience offers extensive GPCR binding and functional screening services to meet the chemical and biological research needs in GPCR drug discovery.
