for MCF-7 nuclear extract (H2O2 post-treated)Background
MCF-7 nuclear extract (H2O2 post-treated) 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.
Treatment of MCF-7 cells with reactive oxygen species (ROS), such as H2O2 triggers an oxidative stress response that leads to toxicity and eventual apoptosis. H2O2 signals an antiproliferative/repair response that induces antioxidant systems to metabolize H2O2 to avert ROS toxicity.
for MCF-7 nuclear extract (H2O2 post-treated)Application Notes
MCF-7 nuclear extract (H2O2 post-treated) is recommended for studies related to 1) breast cancer research, 2) cellular response to oxidative stress and 3) apoptosis.

for MCF-7 nuclear extract (H2O2 post-treated)Extract Composition
MCF-7 nuclear extract was collected in Lysis Buffer. Post-collection treatment consists of exposing the nuclear extract to a final concentration of 200 mM H2O2 for 20 minutes on ice. The Lysis Buffer consists of 20 mM Hepes (pH 7.9), 100 mM KCl, 1 mM MgCl2, 20% glycerol, 0.5 mM PMSF and 0.5 mM DTT. The protein content has been determined by a Bradford-based assay.
for MCF-7 nuclear extract (H2O2 post-treated)Quality Control
Each lot has been tested for Sp1 activity by using the TransAM® Sp1 Kit. The signal intensity for Sp1 activity in each lot is compared to the signal intensity obtained with H2O2-post treated extracts from MCF-7 cells (see figure). Once the signals are blanked, the ratio between the signals from untreated extracts over treated extracts used at 5 µg/well must be above 4.
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.
