PathHunter® U2OS MC4R Bioassay Kit

The PathHunter U2OS MC4R Bioassay Kit provides an easy-to-use cell based assay to measure drug potency and detect neutralizing antibodies. This bioassay asseses ligand (e.g. α-Melanocyte stimulating hormone) based on activation of MC4R GPCR activity via detection of β-Arrestin recruitment. The included cell line overexpresses ProLink-tagged MC4R and EA-tagged β-Arrestin-2. Activation of MC4R stimulates the recruitment of β-Arrestin-2 and produces EFC signal. Bioassay kits are a convenient, ready-to-use format which contains all materials needed to run the assay, including single-use vials of cryopreserved cells, cell plating media, control agonist, detection reagent, and assay plates.

See User Manual for Product Configuration Details. The purpose of the control ligand included in the Bioassay Kit is for verification of assay performance relative to the data shown in the Certificate of Analysis for that kit. This control ligand is not intended for use as a reference standard for validation studies and lot release applications. Typically, a reference medicinal product (RMP) that has been pre-defined by the customer as an internal reference standard is used for those applications. The RMP is not provided with the bioassay kit or supplied by Eurofins DiscoverX.
