Anti-Progesterone Receptor (Phospho-Ser190)

Y011074 by MBP is a rabbit polyclonal antibody detecting progesterone receptor (PGR) phosphorylated at Ser190 of PR-B (Ser26 of PR-A), a CDK2-dependent modification critical for full PR transcriptional activity. PR-B runs at ~120 kDa; PR-A at ~94 kDa. Validated for WB and IHC in human samples. Research Use Only.
