GeneBLAzer™ RXR beta DA Assay Kit

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.

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).

CellSensor™ TrkB-NFAT-bla CHO-K1 Cell Line

Neurotrophins (NGF, BDNF, NT-3, and NT-4) and their transmembrane receptors (TrkA, TrkB, TrkC, and P75NTR) play important roles in the regulation of neuronal and non-neuronal cell proliferation, differentiation, survival, and death. Neurotrophin signaling also mediates higher-order neuronal activities, such as learning, memory, and behavior. Alterations in neurotrophin levels and their receptors have been implicated in neurodegenerative disorders, such as Alzheimer's disease and Huntington's disease, as well as psychiatric disorders. Neurotrophins propagate their signal through activating multiple signaling pathways (e.g., MAPK, PI3K, PKC).

BDNF (brain-derived neurotrophic factor) and its receptor TrkB (also known as NTRK2) play a fundamental role in regulating neural development, survival, and synaptic activity and plasticity. TrkB is also a potential anticancer target, since altered signaling through TrkB promotes tumor formation, survival, and metastasis of various cancers (including neuroblastomas, multiple myelomas, and pancreatic ductal adenocarcinomas). Moreover, growing evidence indicates that BDNF and its receptor influences food intake and body weight control.
