Functional Studies - Cytochrome c Release Assay Kit (AB65311)

5x10e7 Jurkat cells were cultured in the absence (1-2) or presence of 2 uM Camptothecin (CPT) (ab120115) for 24 hours (3-4) or with 10 uM CPT for 4 hours (5-6). 30 uL cytosolic (1, 3, 5) and mitochondrial (2, 4, 6) extracts were loaded onto the gel. Membranes were probed with anti-Cytochrome C Mouse MAb (ab65311) (dilution 1 : 200) followed by Goat Anti-Mouse IgG (HRP) (ab97040) (dilution 1 : 2000).

Bands were detected at the prediced size of 12 kDa.

Inhibition of cytochrome c release from mitochondria in SK-N-SH cells.

Cytochrome C release was measured using Cytochrome C releasing apoptosis assay kit (ab65311). Blots showing immunoreactive bands for cytochrome c in cytosol (Image A). Data was expressed in fold-increase of cytochrome c compared to vehicle. Protein expression levels were normalized to β-actin (Figure B). Blots (Image C) of immunoreactive bands for cytochrome C in mitochondria. Figure D shows a fold-increase of cytochrome C compared to vehicle. Protein expression levels were normalized to COX IV.

Product details

Cytochrome c Release Assay Kit ab65311 provides an effective means for detecting cytochrome c translocation from mitochondria into cytosol during apoptosis.

The kit provides reagents to isolate a highly enriched mitochondria fraction from cytosol. The procedure is simple and easy to perform; no ultracentrifugation is required and no toxic chemicals are involved.

Cytochrome c release from mitochondria into the cytosol is determined by Western blotting using the cytochrome c antibody provided in the kit.

The anti-Cytochrome c antibody is a mouse monoclonal antibody that reacts with denatured human, mouse, and rat cytochrome c.

Cytochrome c release assay protocol summary:
- collect cells, centrifuge and wash with PBS
- resuspend in cytosol extraction buffer mix
- homogenize cells with a dounce tissue grinder
- centrifuge homogenate at 700 x g for 10 min
- collect supernatant and centrifuge at 10,000 g for 30 min, collect supernatant as cytosolic fraction
- resuspend pellet in mitochondrial extraction buffer mix and save as mitochondrial fraction
- analyze cytosolic and mitochondrial fractions in western blotting with cytochrome c antibody

This product is manufactured by BioVision, an Abcam company and was previously called K257 Cytochrome c Releasing Apoptosis Assay Kit. K257-100 is the same size as the 100 test size of ab65311.

Cytochrome c plays an important role in apoptosis. The protein is located in the space between the inner and outer mitochondrial membranes. An apoptotic stimulus triggers the release of cytochrome c from the mitochondria into cytosol where it binds to Apaf-1. The cytochrome c/Apaf-1 complex activates caspase-9, which then activates caspase-3 and other downstream caspases

Supplementary information

Cytochrome c also known as cyt c is a small heme protein with a mass of approximately 12 kDa. It is expressed in the mitochondria of eukaryotic cells across different species. Its mechanical role involves electron transfer within the mitochondrial electron transport chain. Cytochrome c transfers electrons between complex III (cytochrome bc1 complex) and complex IV (cytochrome c oxidase complex) playing a critical role in cellular respiration and energy production.
Biological function summary

Cytochrome c participates in both energy generation and apoptosis. It functions as part of the electron transport chain complex contributing to the maintenance of the mitochondrial membrane potential. When released into the cytosol cytochrome c initiates the apoptotic cascade by binding to Apaf-1 which then forms the apoptosome complex along with procaspase-9. This triggers subsequent caspase activation leading to programmed cell death.

Pathways

Cytochrome c plays a central role in the intrinsic pathway of apoptosis and oxidative phosphorylation. In the apoptotic pathway after release from mitochondria it interacts with Apaf-1 and procaspase-9 eventually activating caspase-3 and other executioner caspases. Additionally during oxidative phosphorylation cytochrome c works closely with cytochrome bc1 and cytochrome c oxidase in the electron transport chain facilitating ATP synthesis.

Cytochrome c is linked with conditions such as cancer and neurodegenerative diseases. Its release from mitochondria is associated with apoptotic cell death which can either suppress tumor development or contribute to cancer cell resistance. In neurodegenerative disorders like Alzheimer's disease impaired cytochrome c function can result in cellular energy deficits and increased apoptosis. The interaction with Apaf-1 is vital in these processes highlighting the importance of cytochrome c in pathology.

Product protocols

Target data

Electron carrier protein. The oxidized form of the cytochrome c heme group can accept an electron from the heme group of the cytochrome c1 subunit of cytochrome reductase. Cytochrome c then transfers this electron to the cytochrome oxidase complex, the final protein carrier in the mitochondrial electron-transport chain.. Plays a role in apoptosis. Suppression of the anti-apoptotic members or activation of the pro-apoptotic members of the Bcl-2 family leads to altered mitochondrial membrane permeability resulting in release of cytochrome c into the cytosol. Binding of cytochrome c to Apaf-1 triggers the activation of caspase-9, which then accelerates apoptosis by activating other caspases.
