The TCA method may reduce the amount of superoxide dismutase (SOD) present, but tends to cause dimerization or acid-modified structures of cytochrome c. In contrast, acetic acid preparations may have slightly higher amounts of SOD, but a lower proportion of dimeric cytochrome c. So C2506 would be recommended for enzyme activity studies that require low SOD, whereas C7752 is recommended for structural studies or binding studies, or for enzyme activity studies where possible SOD contamination is not a problem. The rat PRO and the human HCT116 and HT29 colon cancer cell lines were stably transfected with a construct encoding cytochrome c in an antisense orientation (AS) or an empty vector (C).A, Western blot analysis of cytochrome c, HSP60, and AIF.One representative experiment is shown.

In this study, with isolated liver mitochondria, we demonstrate that cytochrome c release requires a two-step process. The cytochrome complex, or cyt c, is a small hemeprotein found loosely associated with the inner membrane of the mitochondrion. The Cytochrome c Oxidase Assay Kit uses an optimized colorimetric assay based on observation of the decrease in absorbance of ferrocytochrome c measured at 550 nm, which is caused by its oxidation to ferricytochrome c by cytochrome c oxidase. Like many proteins that carry electrons, it contains a special prosthetic group that handles the slippery electrons. Cytochrome c is primarily known as an electron-carrying mitochondrial protein.
