Progesterone Receptor (PGR) Mouse Monoclonal Antibody [Clone ID: PR484]

Specifications

Product Data
Clone Name	PR484
Applications	IHC, WB
Recommend Dilution	Western Blot: 0.5-1 µg/ml for 2 hours at RT.  Immunohistochemistry on Frozen and Formalin-Fixed Paraffin Sections: 0.5-1 µg/ml for 30 min at RT. Staining of formalin-fixed tissues requires boiling tissue sections in 10mM citrate buffer, pH 6.0, for 10-20 min followed by cooling at RT for 20 minutes.  Positive Control: T47-D Cells or Breast Cancers.
Reactivity	Human
Host	Mouse
Clonality	Monoclonal
Immunogen	Recombinant Human Progesterone Receptor protein.
Specificity	This Monoclonal antibody is specific to Progesterone Receptor and shows minimal cross-reaction with other members of the family. Progesterone receptor is expressed as two major isoforms, PR-A (81kDa) and PR-B (116kDa). Expression of PgR has been suggested to reflect a intact estrogen regulatory machinery and therefore, predict better clinical response to endocrine therapy than ER alone. It is excellent for immunohistochemical staining of formalin/paraffin tissues. Cellular Localization: Nucleus.
Formulation	10mM PBS State: Purified State: Liquid purified IgG fraction from Bioreactor Concentrate Stabilizer: 0.05% BSA Preservative: 0.05% Sodium Azide
Concentration	lot specific
Purification	Protein A/G Chromatography
Conjugation	Unconjugated
Storage Condition	Store undiluted at 2-8°C.
Predicted Protein Size	PR-A (81 kDa) and PR-B (116 kDa).
Gene Name	progesterone receptor
Database Link	Entrez Gene 5241 Human UniProt ID P06401
Background	The progesterone receptor (also known as NR3C3) is a member of the steroid or nuclear hormone receptor superfamily family of proteins. Family members are involved in diverse physiological functions including embryonic development, cell differentiation, and homeostasis. The receptors function by binding to DNA in the nucleus and regulating the transcription of target genes. The progesterone receptor is activated by its ligand progesterone, which is a steroid hormone involved in the menstrual cycle, pregnancy and embryogenesis. Progesterone receptor expression status is commonly used as a marker for classifying breast cancers and for predicting prognosis and response to endocrine therapy. That is, antibody positive versus antibody negative tumors can have potential implications with respect to predicted outcome, treatment, or disease monitoring. Progesterone receptor is expressed as two major isoforms, PR-A (81 kDa) and PR-B (116 kDa). These isoforms are generated from alternative transcriptional start sites within the progesterone receptor gene. Both forms are ligand activated by progesterone although they differ in their relative ability to activate target gene transcription. Antibody to progesterone receptor is widely used to study breast and other progesterone receptor containing tissues such as the endometrium. Researchers are encouraged to consult the scientific literature for additional information regarding the use of antibody to measure progesterone receptor as part of assessing breast or other tumor types.
Synonyms	PR, PGR, NR3C3
