Consecutive invasive breast cancer patients were assayed for estrogen receptor (er) and progesterone receptor (pr) by the dextran-coated charcoal method.
A whole-cell assay for measuring estrogen (er) and progesterone (pgr) receptors in monolayer culture of human breast cancer cell lines is described. We now report that cyclin d1 and estrogen regulate progesterone receptor cells were treated with 100 nm estradiol 24 h after transfection and assayed using. The test is called an immunohistochemical staining assay, that a test should be done for both estrogen receptors and progesterone receptors.
