Progesterone Receptor (ZR4)Catalogue number: PR004
For the evaluation of prognosis and hormone dependency of mamma carcinoma oestrogen and progesterone receptors are determined in the affected tissues. Progesterone receptors are regulated by oestrogens. The antibody to progesterone receptor is well suited to detect the nuclear receptor proteins in appropriate processed tissue sections. For evaluation of prognosis it should always be used in parallel with the determination of oestrogen receptor, EGF receptor, cathepsin D and all relevant clinical factors. Cells and tissues, which are stimulated by the steroid hormone progesterone exhibit specific receptor proteins in their cell nuclei, binding the hormone and transducing the signal. Among these cells are epithelial cells of the uterine myometrium as well as normal and hyperblastic epithelial cells of the breast glands. Human progesterone receptor protein .
