Application Abreviews Notes
WB 1/250 - 1/500. Detects a band of approximately 14 kDa.
IP 1/50.
IHC-P 1/100 - 1/250. Perform heat mediated antigen retrieval before commencing with IHC staining protocol.

Use of HRP-conjugated or polymerized HRP secondary antibodies recommended, stronger signals have been found using the polymerized HRP secondary.

ICC 1/50 - 1/100.
  • Application notes
    Is unsuitable for Flow Cyt.
  • Target

    • Function
      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.
    • Involvement in disease
      Defects in CYCS are the cause of thrombocytopenia type 4 (THC4) [MIM:612004]; also known as autosomal dominant thrombocytopenia type 4. Thrombocytopenia is the presence of relatively few platelets in blood. THC4 is a non-syndromic form of thrombocytopenia. Clinical manifestations of thrombocytopenia are absent or mild. THC4 may be caused by dysregulated platelet formation.
    • Sequence similarities
      Belongs to the cytochrome c family.
    • Post-translational
      Binds 1 heme group per subunit.
    • Cellular localization
      Mitochondrion matrix.

    Vielen Dank fuer Ihren Anruf.

    Das Labortestet den Cytochrom C-Antikoerper ab76237 mit nicht-denaturiertem COS-1-Zelllysat in der IP, da ab76237 nur natives Cytochrom C erkennt.

    Ich hoffe, dies hilft Ihnen weiter. Bitte zoegern Sie...
