Immunofluorescent analysis of Phospho-Progesterone Receptor (green) in T47D cells untreated (left) or stimulated with 100nm promegestone, R5020, for 1 hour (right). The cells were fixed with formalin for 15 minutes, permeabilized with 0.1% Triton X-100 in TBS for 10 minutes, and blocked with 3% Blocker BSA (Product # 37525) for 15 minutes at room temperature. Cells were stained with Phospho-Progesterone Receptor pSer190 mouse monoclonal antibody (Product # 37-8200), at a dilution of 1:100 for 1 hour at 37C, and then incubated with a Alexa Fluor 488 superclonal goat anti-mouse IgG secondary antibody (Product # A28175) at a dilution of 1:1000 for 30 minutes at room temperature (both panels, green). Nuclei (both panels, blue) were stained with Hoechst 33342 dye (Product # 62249). Images were taken on a Thermo Scientific ToxInsight at 20X magnification.

37-8200 detects Phospho-Progesterone Receptor in Human samples.
37-8200 has been successfully used in western blot, immunofluorescence and immunohistochemistry in human samples. Phospho-Progesterone Receptor (Ser 190) antibody detects both progesterone receptor A and B forms when phosphorylated at Ser26 and Ser190, respectively.
The human Progesterone Receptor (PgR) is a member of the steroid family of nuclear receptors. PgR is found as a 120 kDa protein (Form B) or a 94 kDa protein (Form A) due to the use of alternative translation initiation sites. In its inactive state, PgR forms a multiprotein complex which includes heat shock proteins and immunophins. Upon binding of progesterone hormone to its receptor, there is a conformational change that allows dimerization and binding of the receptor to progesterone response elements (PRE) sequences, resulting in activated transcription.
