For in vitro diagnostic use.
FLEX Monoclonal Mouse Anti-Human Progesterone Receptor, Clone PgR 1294, Ready-to-Use (Dako Omnis), is intended for use in immunohistochemistry with the EnVision FLEX visualization system together with the Dako Omnis instrument to qualitatively detect human progesterone receptor in formalin-fixed, paraffin-embedded tissue sections of human breast cancer. The antibody binds progesterone receptor-expressing cells and is useful in the assessment of progesterone receptor status in human breast carcinomas.
The clinical interpretation of any staining or its absence should be complemented by morphological studies using proper controls and should be evaluated within the context of the patient's clinical history and other diagnostic tests by a qualified pathologist. This antibody is intended to be used after the primary diagnosis of tumor has been made by conventional histopathology using nonimmunologic histochemical stains.
Indications for use as stated in the FDA summary.
