## Indications for use
The BioGenex Mouse Monoclonal Anti-Progesterone Receptor Antibody (Clone PR88) is an immunohistochemical (IHC) assay and is intended for laboratory use to qualitatively identify by light microscopy human progesterone receptor in normal and/or pathological paraffin-embedded, formalin-fixed tissues. The PR88 antibody specifically binds to antigens located in the nucleus of cell populations that express progesterone receptor in normal and abnormal tissues. This antibody is indicated as an aid in assessing patient response to hormonal therapy and as an aid in the prognosis and management of breast cancer patients. 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. PR88 antibodies have been optimally manufactured for use with BioGenex Super Sensitive MultiLink® Detection Systems with or without BioGenex Automated Staining Systems.
