Immunodetection of estrogen receptors in cell lines of renal cell carcinoma by Western blots. Protein lysates were prepared from cell lines of renal cell carcinoma (ACHN, 786-O, and A498) and breast cancer (T47-D and MCF-7), which served as positive controls. GAPDH (glyceraldehyde-3-phosphate dehydrogenase) was the internal control. ER1 estrogen receptor 1, ER2 estrogen receptor 2
