I see that you list several horse heart cytochrome c products. What are the differences, and which one should I choose?
Product No. C2506 is prepared with trichloroacetic acid (TCA), whereas C7752 is prepared with the milder acetic acid. 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. Product No. C2867 is prepared from C2506; it is a BioUtra grade product, greater than or equal to 99% pure as determined by SDS-PAGE. It is recommended when an ultra-high purity is required. Product No. C3256 is also prepared from C7752; it is isolated by ion-exchange chromatography. This fraction shows a high rate of ascorbic acid oxidation, but low activity in a cytochrome oxidase system. Product No. C7150 is also prepared from C7752; it is suitable for use as a gel filtration molecular weight marker.
How do I determine how much of Product C7752, Cytochrome c, is in the oxidized form, and how much is reduced?
This is determined by a spectral assay. The detailed assay procedure (operating procedure #11252) may be requested from Sigma St. Louis Technical Service (techserv@sial.com).
Is Product C7752, Cytochrome c, predominantly in the oxidized form or the reduced form?
This product is predominantly (>95%) in the oxidized form.
How should I store solutions of Product C7752, Cytochrome c?
Our general recommendations are as follows: Store at -20 °C (freezer) for up to six months. Store at 2-8 °C (refrigerator) for up to two weeks. Store at 20-25 °C (room temperature) for up to three days. According to J. Biol. Chem, 237, 2161-2174 (1962), cytochrome c is stable to boiling, and over an unusually wide range of pH values. However, it denatures readily at extreme pH (low or high), and in high concentrations of organic solvents, such as ethanol or acetone.
