Description
The 66 kDa protein known as the human estrogen receptor (ER antibody) functions as a nuclear hormone receptor that is dependent on estrogen. The nuclei of epithelial cells in normal breast and endometrial tissues, as well as a fraction of breast carcinomas, have been found to contain ER, according to studies. The ER protein’s C-terminal epitope is the target of the SP1 clone, a high affinity rabbit monoclonal antibody. According to studies, the SP1 clone is more sensitive to breast cancer than the mouse monoclonals already on the market. SP1 staining can occasionally be achieved without antigen retrieval.
