|Purpose||This antibody is designed for the specific localization of human PR using IHC techniques in formalin-fixed, paraffin- embedded tissue sections.|
|Characteristics||The determination of steroid hormone receptors is of great importance for therapy of patients with hormone receptor expressing tumours. Progesterone and estrogen receptor positive breast carcinoma patients have demonstrated a better response to endocrine therapy than receptor negative patients. Expression of progesterone receptors in tumour cells of human breast carcinoma points to an intact estrogen receptor and to sensitivity of this tumour to endocrine therapy. Several investigations have shown that progesterone receptor is a better prognostic marker than estrogen receptor. Immunohistochemistry (IHC) is a complex technique in which immunological and histological detection methods are combined. In general, the manipulation and processing of tissues before immunostaining, especially different types of tissue fixation and embedding, as well as the nature of the tissues themselves may cause inconsistent results (Nadji and Morales, 1983). Endogenous pseudoperoxidase and peroxidase activity or endogenous biotin and alkaline phosphatase activity can cause non-specific staining results depending on the detection system used. Tissues that contain Hepatitis B surface antigen (HBsAg) can produce false positives when using HRP detection systems (Omata et al, 1980). Insufficient contrast staining and/or improper mounting of the sample may influence the interpretation of results.|

Staining pattern: Nuclear. The interpretation of the stain results is the full responsibility of the user. Any experimental result must be confirmed by a medically established diagnostic product or procedure.
Principles of the procedure: The demonstrations of antigens by IHC is a sequential procedure with several steps involving first the application of a specific antibody for the antigen of interest (primary antibody), then a secondary antibody which joins to the first, an enzyme complex, and the addition of a chromogenic substrate. The sample is washed between each step. Enzymatic activation of the chromogenic substrate creates a visible product where the antigen is located. The results are interpreted using a light microscope. The primary antibody can be used both in manual IHC and with automated immunostainers.
Paraffin-embedded tissue samples should be used. The antibody is also useful for immunostaining frozen tissue samples. Western blot techniques are not recommended.
Antigen retrieval: HIER Citrate Buffer pH 6.5
Working dilution: (only for concentrates) 1:50 – 1:200
