IHC image of CSB-RA006328MA1HU diluted at 1:50 and staining in paraffin-embedded human prostate cancer performed on a Leica BondTM system. After dewaxing and hydration, antigen retrieval was mediated by high pressure in a citrate buffer (pH 6.0). Section was blocked with 10% normal goat serum 30min at RT. Then primary antibody (1% BSA) was incubated at 4°C overnight. The primary is detected by a Anti-Human lgG, Fcy Fragment Specific labeled by HRP and visualized using 0.05% DAB.

Description

Cytochrome c represents a critical component of the mitochondrial electron transport chain and serves as a key mediator of intrinsic apoptosis. When released from mitochondria into the cytosol, this small heme protein triggers caspase activation cascades that execute programmed cell death. This dual role in cellular respiration and apoptotic signaling makes cytochrome c an essential marker for studying mitochondrial dysfunction, cardiovascular disease mechanisms, and cell death pathways.

This recombinant monoclonal antibody targeting human CYCS offers the reproducibility and consistency that demanding research applications require. Generated against recombinant human CYCS protein and produced as a sequence-defined human IgG1 clone (17H10), this antibody eliminates the lot-to-lot variability that can compromise longitudinal studies and multi-site collaborations. Affinity chromatography purification ensures high specificity for your target.

Validation studies demonstrate reliable performance across multiple experimental platforms. Immunohistochemistry testing on paraffin-embedded human prostate cancer tissue using citrate buffer antigen retrieval shows clear cytoplasmic staining at dilutions between 1:50 and 1:200, making this antibody well-suited for examining cytochrome c expression and localization in clinical specimens. Flow cytometry analysis of fixed and permeabilized A431 cells confirms robust intracellular detection with distinct signal separation from isotype controls, supporting quantitative studies of cytochrome c levels in cell populations.

The antibody's compatibility with both tissue-based and cell-based detection methods provides flexibility for researchers investigating mitochondrial biology, apoptotic mechanisms, and cardiovascular pathophysiology. Whether examining cytochrome c release during cell death or characterizing its expression patterns in disease states, this recombinant antibody delivers the technical performance needed for meaningful experimental outcomes.

Target Background

Function(From Uniprot)

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.
