Anti-PR Antibody

The polyclonal antibody is raised in rabbit against the progesterone receptor (PR), a nuclear steroid hormone receptor that mediates progesterone signaling in reproductive and other target tissues. Antibodies.com supplies this reagent as an unconjugated stock at 1 mg/ml in phosphate buffered saline (pH 7.2) with 0.05% sodium azide as a preservative. Each vial contains 50 µl, and the antibody is validated for Western blot (WB) and immunohistochemistry (IHC) workflows with confirmed reactivity against human, mouse, and rat samples.

PR expression is widely studied as a clinical biomarker in breast cancer pathology and as a marker of hormone-responsive tissues, making a cross-species polyclonal reagent valuable for translational work that bridges rodent models and human specimens. Store refrigerated and protect from light, with aliquoting suggested to limit freeze-thaw cycles and preserve binding activity over time. Intended for research use only in protein expression profiling, tissue staining, and signaling pathway characterization.
