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.

General description
Application
Die Reaktionsorte, an denen die Oxidation von Cytochrom c aus Pferden bei Behandlung mit H2O2 und UV genau stattfindet, sowie der Umfang der Oxidation wurden charakterisiert. Es wurde vorgeschlagen, dass man den Status dieser Oxidationsorte als einen Biomarker für den Oxidationszustand in einer Zelle verwenden könnte.
Cytochrome c from equine heart has been used to prepare a stock solution for synthesizing and calibrating biotinylated cytochrome c.[3] It has also been used as a component of the reaction buffer to stain electron transport chain (ETC) complex IV and determine its activity using blue-native gel electrophoresis.[4]
Biochem/physiol Actions
Cytochrom c ist in erster Linie als mitochondriales Protein mit Elektronencarrier Funktion bekannt. Der Übergang von Cytochrom c zwischen Eisen(II) und Eisen(III) innerhalb der Zelle macht es zu einem effizienten biologischen Elektronen-Transporter, und es spielt eine wichtige Rolle bei zellulären Oxidationen in Pflanzen und Tieren. Es wird allgemein als universeller Atmungskatalysator betrachtet, der eine wesentliche Elektronen-Brücke zwischen den lungengängigen Substraten und Sauerstoff bildet.
Cytochrome C (Cyt C) acts as a potent signaling molecule of apoptosis by activating caspase 3, a death protease. It plays a role in heme-binding with the help of cytochrome c heme lyase which facilitates its release into the mitochondrial intermembrane space.[1] Cyt C also exhibits lipid-binding by interacting with cardiolipin, a phospholipid that initiates protein unfolding and activates the peroxidase function in Cyt C.[5]

I see that you list several horse heart cytochrome c products. What are the differences, and which one should I choose?
1 answer-
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 C2867, Cytochrome c, is in the oxidized form, and how much is reduced?
1 answer-
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).
