Progesterone R/NR3C3 Antibody (SPM566) - IHC-Prediluted from Novus Biologicals, a Bio-Techne Brand

Available conjugates: Available conjugates: Unconjugated

Specificity: This monoclonal antibody is specific to progesterone receptor and shows minimal cross-reaction with other members of the family. Progesterone receptor is expressed as two major isoforms, PR-A (81kDa) and PR-B (116kDa). Expression of PgR has been suggested to reflect a intact estrogen regulatory machinery and therefore, predict better clinical response to endocrine therapy than ER alone. It is excellent for immunohistochemical staining of formalin/paraffin tissues.
