Tango™ HRH3-bla U2OS DA Assay Kit

The Tango™ HRH3-bla U2OS DA (Division Arrested) cells contain the human Histamine Receptor H3 (HRH3) linked to a TEV protease site and a Gal4-VP16 transcription factor stably integrated into the Tango™ GPCR-bla U2OS parental cell line. This parental cell line stably expresses a beta-arrestin/TEV protease fusion protein and the beta-lactamase (bla) reporter gene under the control of a UAS response element.

The Tango™ HRH3-bla U2OS cells and the Tango™ HRH3-bla U2OS DA cells have been functionally validated for Z' factor and EC50 concentrations of Methylhistamine. In addition, Tango™ HRH3-bla U2OS cells have been tested for assay performance under variable conditions. These data are found in the Validation & Assay Performance Summary in the Manuals and Brochures section. DA cells are irreversibly division arrested using a low-dose treatment of Mitomycin C, and have no apparent toxicity or change in cellular signal transduction.
