Rat ERb (Estrogen Receptor Beta) ELISA Kit

The test principle applied in this kit is Sandwich enzyme immunoassay. The microtiter plate provided in this kit has been pre-coated with an antibody specific to Rat ERb. Standards or samples are added to the appropriate microtiter plate wells then with a biotin-conjugated antibody specific to Rat ERb. Next, Avidin conjugated to Horseradish Peroxidase (HRP) is added to each microplate well and incubated. After TMB substrate solution is added, only those wells that contain Rat ERb, biotin-conjugated antibody and enzyme-conjugated Avidin will exhibit a change in color. The enzyme-substrate reaction is terminated by the addition of sulphuric acid solution and the color change is measured spectrophotometrically at a wavelength of 450nm ± 10nm. The concentration of Rat ERb in the samples is then determined by comparing the OD of the samples to the standard curve. Protein Function: Nuclear hormone receptor. Binds estrogens with an affinity similar to that of ESR1/ER-alpha, and activates expression of reporter genes containing estrogen response elements (ERE) in an estrogen-dependent manner , Lacks ligand binding affinity and suppresses ESR1/ER-alpha and ESR2 isoform 1/ER-beta1 mediated transcriptional activation and may act as a dominant negative regulator of estrogen action , Unable to bind DNA and activate transcription due to the truncation of the DNA binding domain , Unable to bind DNA and activate transcription due to the truncation of the DNA binding domain [The Uniprot Consortium]
