描述

GeneBLAzer®RXR beta DA (Division Arrested) cells and RXR beta-UAS-bla HEK 293T cells contain the ligand-binding domain (LBD) of the human Retinoid X Receptor beta (RXR beta) fused to the DNA-binding domain of GAL4 stably integrated in the GeneBLAzer®UAS-bla HEK 293T cell line. GeneBLAzer®UAS-bla HEK 293T cells stably express a beta-lactamase reporter gene under the transcriptional control of an upstream activator sequence (UAS). When an agonist binds to the LBD of the GAL4 (DBD)-RXR beta (LBD) fusion protein, the protein binds to the UAS, resulting in expression of beta-lactamase. 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. Both RXR beta DA cells and RXR beta-UAS-bla HEK 293T cells are functionally validated for Z' and EC₅₀ concentrations of 9-cis retinoic acid (9-cis-RA). In addition, RXR beta-UAS-bla HEK 293T cells have been tested for assay performance under variable conditions, including DMSO concentration, cell number, and stimulation time.
