Anti-PGR (phospho S190) Antibody

This unconjugated rabbit polyclonal IgG reagent from Antibodies.com targets the human progesterone receptor phosphorylated at serine 190, an activating post-translational modification linked to ligand-dependent nuclear receptor signaling. Validated for western blot, immunohistochemistry, and immunofluorescence workflows, the reagent supports studies of steroid hormone-driven transcriptional regulation in breast cancer cell line models and reproductive tissue specimens. Each vial is supplied as 200 µl of liquid antibody for probing phosphorylated receptor pools that distinguish activated versus quiescent receptor states. Researchers investigating hormone receptor crosstalk, endometrial differentiation, or progesterone-responsive gene expression can use the reagent alongside total PGR antibodies to compare phosphorylation status across treatment conditions. The antibody is reactive with human samples and is provided as a polyclonal antibody reagent for research use only.
