Protocols

Specificity / Sensitivity

Cytochrome c (D18C7) Rabbit mAb recognizes endogenous levels of total cytochrome c protein.

Source / Purification

Monoclonal antibody is produced by immunizing animals with a synthetic peptide corresponding to residues surrounding Pro72 of human cytochrome c protein.

Western Blotting

Western Blotting

Western blot analysis of extracts from various cell lines using Cytochrome c (D18C7) Rabbit mAb.

Western Blotting

Western Blotting

Western blot analysis of extracts from HeLa cells, untreated (-) or treated with Staurosporine #9953 (1 μM, 3 hr; +). Cells were fractionated into whole cell lysate (WCL), cytoplasm (Cyto), membrane (Mem), and cytoskeletal/nucleus (Nuc). Membrane fraction includes mitochondria.

IHC-P (paraffin)

IHC-P (paraffin)

Immunohistochemical analysis of paraffin-embedded mouse skeletal muscle using Cytochrome c (D18C7) Rabbit mAb.

Background

Cytochrome c is a well conserved electron-transport protein and is part of the respiratory chain localized to mitochondrial intermembrane space (1). Upon apoptotic stimulation, cytochrome c released from mitochondria associates with procaspase-9 (47 kDa)/Apaf 1. This complex processes caspase-9 from inactive proenzyme to its active form (2). This event further triggers caspase-3 activation and eventually leads to apoptosis (3).
