Extracts have been quality control tested by Western blot and the Electrophoretic Mobility Shift Assay (EMSA).
To ensure stability, we recommend aliquoting the extracts into single-use fractions and then storing them at -80ºC.
Shipped on dry ice. Upon delivery aliquot and store at -80ºC. Avoid freeze / thaw cycles.
T47D cells carry receptors for a variety of steroids and calcitonin. They express mutant tumor suppressor protein p53 protein. Under normal culturing conditions, they express progesterone receptor constitutively and are responsive to estrogen. They are able to lose the estrogen receptor (ER) during long-term estrogen deprivation in vitro. Cells are therefore used as a model for studies of drug resistance to tamoxifen in patients with mutant p53 breast tumors.
