Application

El citocromo c se utiliza como inductor de la apoptosis dependiente de las mitocondrias en varios estudios de investigación. La identificación y la supervisión de los sitios de oxidación en el citocromo c puede tener implicaciones en la evaluación de las enfermedades y estados relacionados con el estrés oxidativo. Podría utilizarse como biomarcador para evaluar el grado de daño oxidativo y la capacidad antioxidante de las células y los tejidos.

El citocromo c es adecuado para utilizar como componente del tampón fosfato para la detección y la evaluación de la actividad del complejo IV mediante electroforesis en gel Blue Native (BN-PAGE). También puede utilizarse para la detección de anión superóxido extracelular (ECSA) en fagocitos renales aislados.
Se caracterizaron los sitios específicos y el grado de oxidación en el citocromo c caballo tratado con H2O2 y UV. Se sugirió que el estado de estos sitios podría utilizarse como biomarcador del entorno oxidativo de una célula.

Biochem/physiol Actions

El citocromo c ha sido identificado como un importante mediador en las vías apoptóticas. La liberación del citocromo c mitocondrial en el citoplasma estimula la apoptosis y se utiliza comúnmente como indicador del proceso apoptótico en la célula.
El citocromo c se conoce fundamentalmente como una proteína mitocondrial transportadora de electrones. La transición del citocromo c entre los estados ferroso y férrico dentro de la célula la convierte en un eficiente transportador biológico de electrones y desempeña un papel vital en las oxidaciones celulares tanto en plantas como en animales. Se considera generalmente como un catalizador universal de la respiración, formando un puente de electrones esencial entre los sustratos respirables y el oxígeno

Questions

1–5 of 5 Questions  
  1. Is Product C7752, Cytochrome c, predominantly in the oxidized form or the reduced form?

    1 answer
    1. This product is predominantly (>95%) in the oxidized form.

  2. I see that you list several horse heart cytochrome c products. What are the differences, and which one should I choose?

    1 answer
    1. 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.

  4. How do I determine how much of Product C7752, Cytochrome c, is in the oxidized form, and how much is reduced?

    1 answer
    1. This is determined by a spectral assay. The detailed assay procedure (operating procedure #11252) may be requested from Sigma St. Louis Technical Service ([email protected]).

  5. How should I store solutions of Product C7752, Cytochrome c?

    1 answer
    1. 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.
