2 x 100 µg of MCF-7 nuclear extract at 2.5 µg/µl.


MCF-7 nuclear extract was prepared from cell cultures of the human MCF-7 breast adenocarcinoma cancer cell line. The MCF-7 cell line was originally derived from a pleural effusion of a 69-year old Caucasian woman with metastatic breast cancer. MCF-7 cells are the best characterized and most commonly utilized cell lines in in vitro breast cancer studies. The MCF-7 cell line has retained several characteristics that are particular to mammary epithelium, including the ability to grow as a monolayer, form domes, and respond to hormones. These cells also display a low metastatic potential, leading to the assumption that they represent an early epithelial adenocarcinoma phenotype. These characteristics make MCF-7 cells an ideal model system to study malignant progression in relation to breast cancer.

Application Notes

MCF-7 nuclear extract is specifically recommended for studies related to breast cancer research.

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.
