Background:Cytochrome c
Cytochrome c is a small, highly conserved, heme-containing protein involved in mitochondrial electron transport. Cytochrome c is released from the mitochondria in response to pro-apoptotic stimuli and serves as a cofactor in initiating the activation of the APAF-1/Caspase-9 complex. The effect of specific proteins and/or small molecules on the initiation of the intrinsic apoptotic pathway can be evaluated in an in vitro system of isolated mitochondria by monitoring the release of cytochrome c.

Product Summary:
The Quantikine Rat/Mouse Cytochrome c Immunoassay is a 2.5 hour solid phase ELISA designed to measure rat and mouse cytochrome c. It contains natural rat cytochrome c and antibodies raised against cytochrome c, and because of the 100% sequence identity of rat and mouse cytochrome c, this kit can be used to accurately quantitate natural rat or mouse cytochrome c in cell lysates and subcellular fractions.
Precision:
Intra-Assay Precision (Precision within an assay)Three samples of known concentration were tested on one plate to assess intra-assay precision.
Inter-Assay Precision (Precision between assays)Three samples of known concentration were tested in separate assays to assess inter-assay precision.

Recovery:
The recovery of rat/mouse Cytochrome c spiked to three levels throughout the range of the assay in various matrices was evaluated.

Linearity:
To assess the linearity of the assay, five or more samples spiked with various concentrations of rat/mouse Cytochrome c in each matrix were diluted with Calibrator Diluent and then assayed.
