Principle of the Assay: VDR ELISA kit applies the competitive enzyme immunoassay technique utilizing a Polyclonal anti-VDR antibody and an VDR-HRP conjugate. The assay sample and buffer are incubated together with VDR-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 VDR concentration since VDR from samples and VDR-HRP conjugate compete for the anti-VDR antibody binding site. Since the number of sites is limited, as more sites are occupied by VDR from the sample, fewer sites are left to bind VDR-HRP conjugate. A standard curve is plotted relating the intensity of the color (O.D.) to the concentration of standards. The VDR concentration in each sample is interpolated from this standard curve.
NCBI and Uniprot Product Information
Uniprot Description
Nuclear hormone receptor. Transcription factor that mediates the action of vitamin D3 by controlling the expression of hormone sensitive genes. Recruited to promoters via its interaction with BAZ1B/WSTF which mediates the interaction with acetylated histones, an essential step for VDR-promoter association. Plays a central role in calcium homeostasis.

Product Notes
The Rat VDR vdr (Catalog #AAA7241577) is an ELISA Kit and is intended for research purposes only. The product is available for immediate purchase. The AAA7241577 ELISA Kit recognizes Rat VDR. It is sometimes possible for the material contained within the vial of "Vitamin D3 receptor (VDR), 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
