The CellSensor® NFAT CHO-K1 DA (Division Arrested) cells contain a beta-lactamase (bla) reporter gene under control of a Nuclear Factor of Activated T Cells (NFAT) response element stably integrated into CHO-K1 cells. Fluorescence activated cell sorting (FACS) was used to isolate clones responsive to stimulation of the NFAT pathway by PMA (Phorbol 12-Myristate 13-Acetate) and Thapsagargin (Thaps). The cell line was validated for DMSO tolerance, cell number, stimulation time, substrate loading conditions, and EC50 concentration of Thaps at a fixed concentration of PMA. 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
This product can serve as a negative control in screening assays performed with specific G-protein coupled receptor (GPCR) DA cells that were made from this same background. These cells can also be used in other assays where a sensitive readout to intracellular changes in calcium is needed.
