Anti-PR (V184) Antibody

Raised in rabbit and affinity-purified against the human progesterone receptor, this unconjugated polyclonal antibody is supplied by Antibodies.com at 1 mg/ml in phosphate buffered saline with 0.05% sodium azide as a preservative, pH approximately 7.2. The reagent is validated for immunohistochemistry on formalin-fixed paraffin-embedded human tissue, where it labels nuclei of PR-positive epithelial cells in normal breast, progesterone-responsive endometrium, and hormone receptor-positive breast carcinomas. Standard HRP-polymer detection with citrate or Tris-EDTA antigen retrieval brings out clean nuclear staining that pathologists rely on when assessing ER/PR/HER2 status. The 100 µL pack size supports multiple staining runs, and the unconjugated format lets researchers pair the antibody with their preferred chromogen, polymer, or fluorescent secondary detection system. Typical applications include breast cancer subtyping research, endometrial cycle studies, and investigation of progesterone signalling in xenograft or patient-derived tissue models.
