The Estrogen Receptor ELISA kits listed below utilize specific antibodies for the plate-based assay of Estrogen Receptor in various samples. Estrogen Receptor is another term for the ESR1 gene, which encodes the protein, estrogen receptor 1 in humans. It has been reported that Estrogen Receptor plays a role in chromatin remodeling, among other functions. Structurally, the ESR1 protein is 595 amino acid residues in length and 66.2 kilodaltons in mass. However, as many as 4 protein isoforms have been identified. It is localized to the cell membrane, nucleus, and cytoplasm of the cell. In terms of tissue specificity, it is widely expressed across many tissue types. This protein is known to be methylated, glycosylated, ubiquitinated, palmitoylated and phosphorylated. Other names for this target antigen include ER, ESR, and ESRA.
The detection range for different Estrogen Receptor ELISA kits can vary, with some assays measuring target concentrations as low as 78 pg/mL and as high as 300 ng/mL. Click on the following ELISA kits for more detailed information, including target reactivity and assay sensitivity.
