Anti-Progesterone receptor Antibody

The progesterone receptor (PR) is a nuclear hormone receptor that mediates progesterone-driven transcriptional programs in reproductive and hormone-responsive tissues. This rabbit polyclonal reagent from Antibodies.com is raised against the human progesterone receptor and supplied unconjugated in a 100 µl volume, ready for use in Western blot, immunohistochemistry, and immunofluorescence workflows.

On Western blot, the antibody recognizes the receptor isoforms, supporting analysis of PR-A and PR-B expression in breast, endometrial, and reproductive tissue lysates. In immunohistochemistry, the reagent produces nuclear staining consistent with the receptor's role as a transcription factor and is compatible with formalin-fixed paraffin-embedded sections when paired with appropriate antigen retrieval.

The unconjugated format allows flexible pairing with HRP, biotin, or fluorophore-conjugated secondary antibodies for chromogenic IHC or multicolor immunofluorescence panels. Store at -20°C in small working aliquots to limit freeze-thaw cycles of the stock reagent. Intended for research use only.
