Background: ER alpha/NR3A1

Estrogen Receptor alpha is a 65 kDa protein and a member of the steroid family of nuclear receptors. Estrogen Receptor alpha is a ligand-activated transcription factor that, when bound to estrogen, induces a conformational change that allows dimerization and binding to estrogen response element sequences. When bound to DNA, Estrogen Receptor alpha can positively or negatively regulate gene transcription. Like other steroid hormone receptors, Estrogen Receptors are intracellular proteins. Estrogen Receptors play an important role in regulating mammary gland growth and differentiation. Breast tumors that are ER positive may also show a more favorable response to anti-estrogen therapies

    Verified Customer | Posted 11/27/2023
    Estrogen receptor alpha immunoreactivity in horse oviduct. NB100-81909 did not produce any labeling in sections known to be ERa positive.
    NB100-81909 was left on tissue sections for 30m at room temperature and was diluted up to 2ug per mL. Two different buffers for heat-induced epitope retrieval were also tested. Longer incubation times and higher concentrations were not tested due to finding nonspecific labeling of smooth muscle and other tissue elements.
