This Estrogen Receptor alpha antibody is un-conjugated
Application
Western Blotting (WB), Immunoprecipitation (IP), Chromatin Immunoprecipitation (ChIP), Gel Shift (GS), Inhibition Assay (InhA)
Cross-Reactivity
Chicken, Cow, Dog, Hamster, Human, Mouse, Pig, Rabbit, Rat, Sheep
Characteristics
The estrogen receptor (ER) gene consists of more than 140kb of genomic DNA divided into 8 exons, being translated into a protein with six functionally discrete domains required for transcription activation function, binding to estrogen response element (ERE) constitutive dimerization, binding to heat shock proteins, and ligand recognition. The ER is an important regulator of growth and differentiation in the mammary gland. Presence of ER in breast tumors indicates an increased likelihood of response to anti-estrogen (e.g. tamoxifen) therapy.
Purification
Protein A/G Chromatography
Immunogen
Hybridoma produced by the fusion of splenocytes from mice
immunized with the 35 kDa C-terminal fragment (aa 302-595) of human ER expressed in E. coli and mouse myeloma cells.

Application Notes
This antibody can be used gel supershift assays (neat concentration), immunoprecipitation on native and denatured lysate (2 μg/mg of protein lysate), Western blotting (1-2 μg/mL) and chromatin precipitation. Can also be used to block binding of estrogen to the estrogen receptor. Optimal concentration should be evaluated by serial dilutions.
