Extracts have been quality control tested by Western blot and the Electrophoretic Mobility Shift Assay (EMSA).
Cells were cultured in medium supplemented with 1 nM Estradiol for 96 hours at 37°C immediately prior to harvesting.
Aliquot and store at -80°C. Avoid repeated freeze / thaw cycles.
MCF-7 cells are a well-characterized estrogen receptor (ER) positive control cell line (cells are positive for cytoplasmic estrogen receptors) and therefore are a useful in vitro model of breast cancer to study the role of estrogen in breast cancer. Cells are also positive for cytokeratin and negative for desmin , endothelin , GFAP, neurofilament, vimentin.
