General description

Anti-Estrogen Receptor-α Antibody detects endogenous levels of total Estrogen Receptor-α protein.
Estrogen receptor α (ERα) is a member of the nuclear receptor superfamily. It is also known as ESR1 (estrogen receptor). It is located on human chromosome 6q25.1.

Immunogen

The antiserum was produced against synthesized peptide derived from human Estrogen Receptor-alpha.

Immunogen Range: 136-185

Biochem/physiol Actions

Estrogen receptor α (ERα) is involved in immune and inflammatory response. Aberrations in ESR1 results in Mayer-Rokitansky-Küster-Hauser syndrome that is associated with the congenital absence of the uterus and the upper two-thirds of the vagina.
