Anti-Estrogen receptor 1 Antibody

The Anti-Estrogen receptor 1 Antibody from Antibodies.com is a rabbit polyclonal IgG reagent raised against the human ESR1 (ERα) protein, a 67 kDa ligand-activated nuclear hormone receptor that mediates the transcriptional response to 17β-estradiol. This unconjugated antibody is validated for Western blot (WB) detection of endogenous ESR1 in lysates from ER-expressing human cell lines such as MCF-7 and T47D, supporting studies in breast cancer, endometrial, and bone biology research.

Each vial contains 100 µg of antibody in liquid format, supplied unconjugated for compatibility with HRP, biotin, or fluorophore-based secondary detection chemistries. For best stability, store at -20 °C in working aliquots to limit freeze-thaw cycles; small working stocks may be kept refrigerated at 4 °C for short-term use. This reagent is intended for research use only.
