Background

MDA-MB-231 nuclear extract was prepared from cell cultures of the human breast adenocarcinoma MDA-MB-231 cell line. The MDA-MB-231 cell line was derived from a pleural effusion of a 51 year old Caucasian female with an intraductal carcinoma. Although MDA-MB-231 cells are epithelial in morphology, they display a mesenchymal-like/ER-negative/ERBB2-negative phenotype. These cells are characterized by the expression of epidermal growth factor receptor (EGFR) and transforming growth factor α receptor (TGFRα). EGFR and TGFR are receptors that are most commonly associated with human tumorigenesis. Interestingly, although MDA-MB-231 cells express EGFR, they lack a proliferative response to EGF. MDA-MB-231 cells are most frequently used in research as a model for breast adenocarcinoma.

Application Notes

MDA-MB-231 nuclear extract is specifically recommended for breast cancer studies.

Extract Origin

Human breast adenocarcinoma mammary gland

Extract Composition

MDA-MB-231 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).

Quality Control

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

Storage

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.
