  • 产品概述

    The Complex IV Human Enzyme Activity Microplate Assay Kit is used to determine the activity of cytochrome c oxidase in a human sample with greater speed and simplicity. The COX enzyme is immunocaptured within the wells of the microplate and activity is determined colorimetrically by following the oxidation of reduced cytochrome c by the absorbance change at 550 nm. Included in this kit for performance of the activity assay are buffer, detergent, substrate, and 96-well microplate with monoclonal antibody pre-bound to the wells of the plate, allowing for a stream-lined assay.

  • 说明

    Store Tube 1, detergent, and microplate at 4°C – DO NOT FREEZE. Store Reagent C at -20°C or at -80°C for long-term storage.

Complex IV Human Enzyme Activity Microplate Assay Kit 图像

  • Abcam's enzyme activity assays apply a novel approach, whereby target enzymes are first immunocaptured from tissue or cell samples before subsequent functional analysis. All of our ELISA kits utilize highly validated monoclonal antibodies and proprietary buffers, which are able to capture even very large enzyme complexes in their fully-intact, functionally-active states.

    Capture antibodies are pre-coated in the wells of premium Nunc MaxiSorp™ modular microplates, which can be broken into 8-well strips. After the target has been immobilized in the well, substrate is added, and enzyme activity is analyzed by measuring the change in absorbance of either the substrate or the product of the reaction (depending upon which enzyme is being analyzed). By analyzing the enzyme's activity in an isolated context, outside of the cell and free from any other variables, an accurate measurement of the enzyme's functional state can be understood.
  • Figure 1. To determine the activity in the sample, calculate the slope by using microplate software or by manual calculations using one of the two methods shown. Compare the sample rate with the rate of the control (normal) sample and with the rate of the null (background) to get the relative Complex IV activity. (A)The rate is determined by calculating the gradient of the initial slope over the linear region. (B) The rate is determined by calculating the slope between two points within the linear region.

Good Average 3/5 (Ease of Use)
this kit was disigned for use of human samples. I was try to use it to test the porcine kidney and myocardio. The good news is it worked for both tissues.

My guess is that the levels of OXPHOS proteins in whole blood are below the level of detection for activity assays. The activity assays for the most part require higher loading than the sandwich ELISA assays. We have tested Complex IV Quantity with who...

Thank you for your patience in awaiting our reply. This kit was developed using tissue or cell celtures, and we would expect a higher reading than you got in those types of samples.

Technically no reason why you couldn’t – however I think the concentration of extracellular COX would be very low in serum or plasma even in cases of tissue damage.

Thank you very much for having patience!

I looked at the data -the curve lost linearity after 50 sec because the substrate presumably is starting to deplete (there is less reduced cytochrome c as the enzyme clearly is using it). A way around t...

Thank you very much for your email.

I can confirm that I am still working on your inquiry. I will send you the solution soon.

Thank you very much for having patience!

Thank you for contacting us.
In order to help you with your question we need more information about the protocol used. Please submit any raw data you have.

We will look forward to hearing from you soon.

Thank you for contacting us.

Same process for converting all to molarity per amount of protein loaded into well.
Note these are all per cm and should be converted into path length for microplate which should be about 0.6cm.
