Monoclonal Mouse Anti-Human Estrogen Receptor, Clone 1D5 may be used in the semi-quantitative detection of human estrogen receptor in tissue sections of human breast cancer by immunohistochemistry. The information gained by this assay can aid in assessing the likelihood of response to therapy as well as in the prognosis and management of breast cancer patients.
The clinical interpretation of any positive staining or its absence should be complemented by morphological and histological studies with proper controls. Evaluations should be made within the context of the patient’s clinical history and other diagnostic tests by a qualified individual having knowledge of all the potential antibody reactivities.
