Target description

Progesterone receptor (UniProt: P06401; also known as PR, Nuclear receptor subfamily 3 group C member 3) is encoded by the PGR (also known as PR, NR3C3) gene (Gene ID: 5241) in human. Progesterone receptor, a member of the superfamily of steroid receptors, mediates the action of progesterone on its target tissues. Two major isoforms of progesterone receptor, known as progesterone receptor A (PR-A) and PR-B, have been described. They are structurally related, but functionally distinct proteins, produced by transcription from alternative estrogen-inducible promoters and alternate translational sites within a single PR gene. Depending on the isoform, progesterone receptor may function as transcriptional activator or repressor. In reproductive tissues the expression of isoform A and B varies as a consequence of developmental and hormonal status. Both isoforms are expressed in comparable amounts in the uterine glandular epithelium during the proliferative phase of the menstrual cycle. However, the expression of isoform B persists in the glands during mid-secretory phase. In the stroma, isoform A is the predominant form throughout the cycle. Progesterone receptor is phosphorylated on multiple serine residues in a hormone-dependent manner. Phosphorylation on serine 294 that occurs preferentially on isoform B is highly hormone-dependent and modulates ubiquitination and sumoylation on lysine 388. Phosphorylation on serine 102 and 345 is also hormone dependent. Basal phosphorylation on serine residues 81, 162, 190, and 400 is also increased in response to progesterone and can be phosphorylated in vitro by the Cdk2-A1 complex. Phosphorylation at serine 162 and 294, but not at 190, is impaired during the G2/M phase of the cell cycle. This ZooMAb® recombinant monoclonal antibody, generated by our propriety technology, offers significantly enhanced specificity, affinity, reproducibility, and stability over conventional monoclonals.

Physical form

Purified recombinant rabbit monoclonal antibody IgG, lyophilized in PBS with 5% Trehalose, normal appearance a coarse or translucent resin. The PBS/trehalose components in the ZooMAb formulation can have the appearance of a semi-solid (bead like gel) after lyophilization. This is a normal phenomenon. Please follow the recommended reconstitution procedure in the data sheet to dissolve the semi-solid, bead-like, gel-appearing material. The resulting antibody solution is completely stable and functional as proven by full functional testing. Contains no biocide or preservatives, such as azide, or any animal by-products. Larger pack sizes provided as multiples of 25 μL.


300 μg/mL after reconstitution at 25 μL per vial. Please refer to guidance on suggested starting dilutions and/or titers per application and sample type.

Storage and Stability

Recommend storage of lyophilized product at 2-8°C; Before reconstitution, micro-centrifuge vials briefly to spin down material to bottom of the vial; Reconstitute each vial by adding 25 μL of filtered lab grade water or PBS; Reconstituted antibodies can be stored at 2-8°C, or -20°C for long term storage. Avoid repeated freeze-thaws.
