• Product overview

  Contains 30 or 90 dipsticks and necessary components to quantify the activity of the cytochrome c oxidase enzyme complex from human and bovine samples. The kit includes sufficient materials to generate a standard curve and evaluate several unknown samples.

  
  The isolation of mitochondria is not necessary for the performance of this assay. In this kit the specificity of anti-COX monoclonal antibodies (mAbs) is combined with traditional methods for determining COX enzyme activity by histochemical methods and in-gel activity assays. First, the COX enzyme complex is immnocaptured (i.e immunoprecipated in active form) on the dipstick. Second, the dipstick is immersed in COX activity buffer containing reduced cytochrome c and di-amino benzidinetetrachloride (DAB), which serves as the reporter of COX activity. Immunocaptured COX oxidizes cytochrome c, which then oxidizes DAB to form a red-colored precipitate at the COX antibody line on the dipstick. In addition to being quick, the reaction is cyanide-sensitive. The signal intensity of this precipitate corresponds to the level of COX activity in the sample. The signal intensity is best measured by a dipstick reader or may be analyzed by another imaging system.

• Notes

  Store dipsticks at room temperature in their provided container and out of direct sunlight. High humidity conditions should be avoided.

  Store Buffer A, B, and C at 4°C or at -20°C for long term storage.

  Store Tubes 1 and 2 at -80°C; they can also be aliquoted upon receipt to prevent freeze/thaw cycles.

  Tube 3 can be stored at room temperature.

  Functional Studies - Complex IV Human Enzyme Activity Dipstick Assay Kit (ab109876)
  Abcam's enzyme activity assays apply a novel approach, whereby target enzymes are first immunocaptured from tissue or cell samples before subsequent functional analysis. Dipstick ELISA Kits extend this concept by utilizing the well-established lateral flow concept, wherein capture antibodies are striped onto nitrocellulose membrane and a wicking pad draws the sample through the antibody bands. 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.

  Figure 2. An example using ab109876 to measure Complex IV activity in fibroblast protein extracts. Based on the standard curve, 50 µg of protein extract were loaded onto a dipstick for each sample. The figure shows four developed dipsticks, a control sample (1) and four unknowns (2-6). The analysis of the signal intensity and interpolation from the standard curve showed that the unknown samples have between 15-61% of normal Complex IV activity levels.
