Principle of the Assay: GR ELISA kit applies the competitive enzyme immunoassay technique utilizing a polyclonal anti-GR antibody and an GR-HRP conjugate. The assay sample and buffer are incubated together with GR-HRP conjugate in pre-coated plate for one hour. After the incubation period, the wells are decanted and washed five times. The wells are then incubated with a substrate for HRP enzyme. The product of the enzyme-substrate reaction forms a blue colored complex. Finally, a stop solution is added to stop the reaction, which will then turn the solution yellow. The intensity of color is measured spectrophotometrically at 450nm in a microplate reader. The intensity of the color is inversely proportional to the GR concentration since GR from samples and GR-HRP conjugate compete for the anti-GR antibody binding site. Since the number of sites is limited, as more sites are occupied by GR from the sample, fewer sites are left to bind GR-HRP conjugate. A standard curve is plotted relating the intensity of the color (O.D.) to the concentration of standards. The GR concentration in each sample is interpolated from this standard curve.
NCBI and Uniprot Product Information
NCBI Description
This gene encodes glucocorticoid receptor, which can function both as a transcription factor that binds to glucocorticoid response elements in the promoters of glucocorticoid responsive genes to activate their transcription, and as a regulator of other transcription factors. This receptor is typically found in the cytoplasm, but upon ligand binding, is transported into the nucleus. It is involved in inflammatory responses, cellular proliferation, and differentiation in target tissues. Mutations in this gene are associated with generalized glucocorticoid resistance. Alternative splicing of this gene results in transcript variants encoding either the same or different isoforms. Additional isoforms resulting from the use of alternate in-frame translation initiation sites have also been described, and shown to be functional, displaying diverse cytoplasm-to-nucleus trafficking patterns and distinct transcriptional activities (PMID:15866175).

Uniprot Description
GR: transcription factor of the nuclear receptor family. Receptor for glucocorticoids (GC). Binds to glucocorticoid response elements (GRE) and modulates other transcription factors.

Product Notes
The Rat GR nr3c1 (Catalog #AAA752565) is an ELISA Kit and is intended for research purposes only. The product is available for immediate purchase. The AAA752565 ELISA Kit recognizes Rat GR. It is sometimes possible for the material contained within the vial of "Glucocorticoid receptor, ELISA Kit" to become dispersed throughout the inside of the vial, particularly around the seal of said vial, during shipment and storage. We always suggest centrifuging these vials to consolidate all of the liquid away from the lid and to the bottom of the vial prior to opening. Please be advised that certain products may require dry ice for shipping and that, if this is the case, an additional dry ice fee may also be required.Precautions
