Anti-Estrogen Receptor antibodies are protein reagents that detect specific antigens. The Estrogen Receptor antigen is another term for the human protein estrogen receptor 1, encoded by the ESR1 gene. The protein is known to function in chromatin remodeling, among other biological roles. Canonically, it has an amino acid length of 595 residues and a mass of 66.2 kilodaltons. Its subcellular localization is in the cell membrane, nucleus, and cytoplasm and it is widely expressed across many tissue types. The Estrogen Receptor protein is a member of the Nuclear hormone receptor protein family. Other alias names for Estrogen Receptor include ER, ESR, and ESRA. Western Blot is the most common application for the Estrogen Receptor antibodies listed below. ELISA and Immunohistochemistry are also common applications.
