Additional Information

Alternative name: Estrogen Receptor

Immunogen: A synthetic peptide derived from C-terminus of human estrogen receptor.

Format: Ig-fraction

Specificity: Recognizes a protein named estrogen receptor (ER) alpha. The ER gene consists of more than 140kb of genomic DNA divided into 8 exons, being translated into a protein with six functionally discrete domains, labeled A through F. This antibody strongly stains the nucleus of epithelial cells in breast carcinomas. 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. This antibody cross reacts with mouse, rat and hamster.

Application Details

Application Notes: Titer/Working Dilution: This antibody may be diluted to a titer of 1:50-1:100 in an ABC method. However, depending on the staining conditions employed, we suggest that final dilution should be determined by the user. Staining Protocol: We suggest an incubation period of 30 minutes at room temperature. However, depending upon the fixation conditions and the staining system employed, optimal incubation conditions should be determined by the user. Formalin fixed paraffin embedded tissue sections require high temperature antigen unmasking with 10 mM citrate buffer, pH 6.0 prior to immunostaining. Positive Control: Breast carcinoma. Cellular localization: Nuclear

Concentration: 100ug/ml approximately

Buffer: Purified immunoglobulin fraction of rabbit antiserum against estrogen receptor containing sodium azide as preservative.

Storage: Store the antibody at 2-8o c. Do not use it beyond the expiration date stated on the label.

Research Area: Hormones, Receptors

Restrictions: For Research Use. CE-certified for In Vitro Diagnostics (IVD) Use in the European Union
