for A-431 nuclear extractBackground

A-431 nuclear extract was prepared from cell cultures of the human epidermoid carcinoma A431 cell line. These cells are characterized by abnormally high levels of expression of epidermal growth factor receptor (EGFR), approximately 3 x 106/cell, on the cell surface and exhibits a biphasic response to varying concentrations of epidermal growth factor (EGF). Specifically, lower (pmol) concentrations of EGF stimulates cell growth while higher (nmol) concentrations inhibits cell growth and induces terminal differentiation. Therefore, these cells are commonly used as a positive control for EGFR expression and in studies of EGFR downstream signaling cascades. These cells are also highly responsive to mitogenic stimuli and are naturally devoid of p53 and so are also frequently used in cancer and cell cycle-associated studies.

for A-431 nuclear extractApplication Notes

A-431 nuclear extract is specifically recommended for analysis of 1) EGFR expression and downstream signaling cascades, 2) cell cycle, and 3) cancer-associated signaling pathways.

Human Epidermoid Carcinoma

for A-431 nuclear extractExtract Composition

A-431 nuclear extract is supplied in Dilution Buffer (20 mM Hepes (pH 7.9), 100 mM KCl, 1 mM MgCl2, 20% glycerol, 0.5 mM PMSF and 0.5 mM DTT).

for A-431 nuclear extractQuality Control

Extracts have been quality control tested by Western blot and the Electrophoretic Mobility Shift Assay (EMSA).

for A-431 nuclear extractStorage

To ensure stability, extracts should be stored at -80°C.

We recommend aliquoting the extracts into single-use fractions and then storing them at -80°C. This eliminates repeated freeze/thaw cycles.
