Cleaved caspase 7 and 8

The anti-PARP, Survivin, Mcl-1, XIAP, Bcl-2, Bcl-X_L, p15, p21, Cyclin D1, p-IKKα/β, IKKα, IKKβ, p-IκBα, IκBα, p-JNK, JNK, p65, Tubulin, RelB, Caspases-7 and -8, cleaved Caspase-7 and -8 antibodies were purchased from Cell Signaling (Cell Signaling Technology, Danvers, MA). The anti-Cyclin B1 antibody was purchased from Abnova (Abnova, Taipei, Taiwan). The anti-Cyclin E1 antibody was purchased from Zymed (Zymed, San Francisco, CA). The anti-p27 antibody was purchased from Becton Dickinson (BD, San Diego, CA). The anti-A20 antibody was purchased from eBioscience (eBioscience, San Diego, CA). The anti-histone H3 antibody was purchased from Abcam (Abcam, Cambridge, UK). The anti-Caspase-3 and cleaved Caspase-3 antibodies were purchased from Imagenex (Imagenes, San Diego, CA). The anti-β-actin antibody was purchased from Sigma (Sigma, St. Louis, MO).
The MDA-MB-468 and SW527 cell lysate was subjected to SDS-PAGE and transferred onto polyvinylidene fluoride (PVDF) membranes. The membranes were incubated with diluted primary antibodies, horseradish peroxidase (HRP) conjugated secondary antibodies (Jackson ImmunoResearch Laboratory, West Grove, PA), and Western Lighting Chemiluminescence Reagent Plus (PerkinElmer Life Sciences, Shelton, CT) and were visualized on an ImageQuant LAS4000 Biomolecular imager to determine the expression levels of specific proteins.
