Cell Fractionation Kit - Standard

Figure 1. Apoptosis was induced in Jurkat, HeLa and 143B osteosarcoma cells by treatment with staurosporine or in Jurkat cells by FAS. Mitochondrial and cytoplasmic fractions were isolated using Cell Fractionation Kit - Standard (ab109719) and probed using Cytochrome c Apoptosis WB Antibody Cocktail (ab110415). As is clear from the gels, cytochrome c has translocated partially in FAS-induced cells and STS-treated osteosarcoma cells, and almost completely in STS-treated Jurkat and HeLa cells. The three control targets allow for verification of the "cleanness" of the cell fractionation.

Figure 2. Cytoplasmic (C), mitchondrial (M) and nuclear (N) fractions of HepG2 cells were prepared as described in the protocol of Cell Fractionation Kit - Standard (ab109719). Fractions were analyzed by Western blotting using Cytochrome c Apoptosis WB Antibody Cocktail (ab110415) containing antibodies against mitochondrial matrix (pyruvate dehydrogenase subunit E1α, PDH E1α), mitochondrial inner membrane (F1-ATPase α (CV α)), mitochondrial intermembrane space (cytochrome c) and cytosolic (glyceraldehyde-3-phosphate dehydrogenase, GAPDH) markers as well as with antibodies against additional mitochondrial matrix (Hsp70) and nuclear (poly (ADP-ribose) polymerase, PARP and SP1) markers, followed by appropriate HRP-conjugated goat secondary antibodies and ECL detection.
