Anti-Estrogen Receptor (ER), clone 3F174

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. Applications: Suitable for use in Western Blot and Immunohistochemistry. Other applications not tested. Recommended Dilutions: Western Blot: 0.5-1.0ug/ml for 2hrs at RT, Immunohistochemistry (formalin/paraffin): 0.4-0.8ug/ml for 30 min at RT. Staining of formalin-fixed tissues requires boiling tissue sections in 10mM citrate buffer, pH 6.0, for 10-20 min followed by cooling at RT for 20 min. Optimal dilutions to be determined by the researcher. Positive Control: MCF-7 cells, Breast carcinoma , Storage and Stability: May be stored at 4°C for short-term only. Aliquot to avoid repeated freezing and thawing. Store at -20°C. Aliquots are stable for 12 months. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap.
