  • Product overview

    MitoTox™ Complex V OXPHOS Activity Assay Kit (ab109907) is designed for testing the direct inhibitory effect of compounds on Complex V activity in only 4 hours. Complex V extracted from the provided bovine heart mitochondria (a rich source of Complex V) is immunocaptured by specific antibodies on the plate. Complex V activity can be observed as decrease in absorbance at OD 340 nm. The intra-assay and inter-assay variation of this assay are both < 10%.

    Inhibitory effects of compounds on Complex I activity can be tested in two different ways: 1. Screening format, where up to 23 compounds can be tested at a single concentration in triplicate; 2. Dose response (IC50) format, where two compounds known to affect Complex V activity can be tested at 11 different data points in triplicate.

    Testing for mitochondrial function has become a key aspect of drug discovery. Mitochondria can be affected by drug treatment, resulting into cardio- and hepatotoxic side effects that can lead to drug withdrawal from the market. Therefore, there is increasing emphasis on testing the impact on mitochondria early on in the drug development process to reduce failure rates during preclinical and clinical phases. 

  • Notes

    Store Phospholipids, Bovine heart mitochondria and Activity Buffer at -80°C. Store all other components at 4°C.

  • Platform



  • Dose response curve for aurovertin, a non-competitive inhibitor of Complex V.

  • Typical dose response curve for oligomycin. Assay was performed following the Dose Response Assay Procedure using oligomycin, a well known Complex V inhibitor. Oligomycin was prepared in DMSO to generate a 10 mM stock. Starting with a 50 µM final concentration in well, 1:10 serial dilutions of oligomycin were generated.

Customer reviews and Q&As

Thank you for contacting us.

Unfortunately none of our products measure the forward reaction. As far as I know there are no companies selling kits measuring the forward reaction of the ATP synthase I am afraid.

I am sorry I could no...

Product code: 109714 Inquiry: Hi Abcam, Do you know if this kit will immunocapture the ATP synthase enzyme from C. elegans? Unlikely unfortunately – this kit was tested positive with human, rat and cow. Mouse was negative. I think it is unl...

Unfortunately not. It comes with a sample (bovine) which cannot be substituted for mouse.

The rate quoted in the booklet is mOD/min. I think this customer is quoting OD. Therefore 0.12/18 is 0.0067 OD/min = 6.7 mOD/min

Changing the window analyzed to identify the steepest straight line slope is necessary and then to compare all sa...
