Product Information

Product Description

The PathScan® Total Estrogen Receptor α Sandwich ELISA Kit is a solid phase sandwich enzyme-linked immunosorbent assay (ELISA) that detects endogenous levels of estrogen receptor α protein. An Estrogen Receptor α Rabbit mAb has been coated onto the microwells. After incubation with cell lysates, both phospho- and nonphospho-estrogen receptor α proteins are captured by the coated antibody. Following extensive washing, an Estrogen Receptor α Mouse Detection mAb is added to detect captured estrogen receptor α proteins. Anti-mouse IgG, HRP-linked antibody is then used to recognize the bound detection antibody. HRP substrate, TMB, is added to develop color. The magnitude of absorbance for the developed color is proportional to the quantity of estrogen receptor α protein.

*Antibodies in this kit are custom formulations specific to kit.

Protocol

Specificity / Sensitivity

PathScan® Total Estrogen Receptor α Sandwich ELISA Kit detects endogenous levels of estrogen receptor α protein in human cells, as shown in Figure 1. The kit sensitivity is shown in Figure 2. This kit detects proteins from the indicated species, as determined through in-house testing, but may also detect homologous proteins from other species.

Species Reactivity:

Human

Background

Estrogen receptor α (ERα), a member of the steroid receptor superfamily, contains highly conserved DNA binding and ligand binding domains (1). Through its estrogen-independent and estrogen-dependent activation domains (AF-1 and AF-2, respectively), ERα regulates transcription by recruiting coactivator proteins and interacting with general transcriptional machinery (2). Phosphorylation at multiple sites provides an important mechanism to regulate ERα activity (3-5). Ser104, 106, 118, and 167 are located in the amino-terminal transcription activation function domain AF-1, and phosphorylation of these serine residues plays an important role in regulating ERα activity. Ser118 may be the substrate of the transcription regulatory kinase CDK7 (5). Ser167 may be phosphorylated by p90RSK and Akt (4,6). According to the research literature, phosphorylation at Ser167 may confer tamoxifen resistance in breast cancer patients (4).
