  • Product overview

    This rapid multiplexing microplate kit is used to determine both the activity and quantity of cytochrome c oxidase in a human sample with greater speed and simplicity. The ratio of the two is a measure of specific activity. The COX enzyme is immunocaptured within the wells of the microplate and the activity is determined by following the oxidation of reduced Cytochrome c colorimetrically by the absorbance change at 550 nm. Subsequently, in these same wells the quantity of the enzyme can then be determined by adding a COX specific detector antibody and the appropriate alkaline phophatase conjugated antibody; this phosphatase changes a substrate from colorless to yellow at 405 nm. This reaction takes place in a time dependent manner proportional to the amount of protein captured in the wells. Included in this kit for performance of the multiplexing assay are buffers, detergent, substrates, and 96-well microplate with monoclonal antibody pre-bound to the wells of the plate, allowing for a stream-lined assay.

Yes, we use 10% detergent in ab109910 which is available as ab109857 so the final is 1%. This detergent is pretty mild and yields native functional enzymes.

Also, a final of 1.5% could be used (i.e. extraction buffer) without significantly c...

The slope to measure is the fast decreasing slope. The cytochrome c oxidase activity assay measures the capacity of the immunocapture enzyme for oxidizing reduced cytochrome c. Reduced cytochrome c is measured at 550nm. A reduction in the reading means...

We have not tested the enzyme activity portion of the assay (ab109910) after overnight incubation at 4C. My suggestion is to not do it and stick to the conditions set out in the protocol = 3 hours incubation of sample at RT – then perform the act...
