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.

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.

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

Sample Type Average % Recovery Range %
PBS/0.01% Saponin (n=2) 94 90-98
PBS/0.05% Tween 20 (n=2) 101 100-102
PBS/0.5% Triton X-100 (n=2) 100 96-106
PBS/1% Triton X-100 (n=2) 98 95-101
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.

Preparation and Storage
  • Storage
    Store the unopened product at 2 - 8 °C. Do not use past expiration date.
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.

    Assay Procedure
    Refer to the product for complete assay procedure.

    Bring all reagents and samples to room temperature before use. It is recommended that all samples, standards, and controls be assayed in duplicate.
    1.   Prepare all reagents, standard dilutions, and samples as directed in the product insert.
    2.   Remove excess microplate strips from the plate frame, return them to the foil pouch containing the desiccant pack, and reseal.

    3. 75 µL Conjugate
    4.   Add 75 µL of Conjugate to each well.

    5. 50 µL Standard, Control, or Sample
    6.   Add 50 µL of Standard, Control, or sample to each well. Cover with a plate sealer, and incubate at room temperature for 2 hours.
    7.   Aspirate each well and wash, repeating the process 4 times for a total of 5 washes.

    8. 100 µL Substrate Solution
    9.   Add 100 µL Substrate Solution to each well. Incubate at room temperature for 30 minutes. PROTECT FROM LIGHT.

    10. 100 µL Stop Solution
    11.   Add 100 µL of Stop Solution to each well. Read at 450 nm within 30 minutes. Set wavelength correction to 540 nm or 570 nm.
