What is the difference between these 2 kits? Why does one immunocapture the complex II while the other does not? Are there any advantages/disadvantages of the immunocapture? Why is the complex III kit solely called complex III when based on the description it sounds like complex II activity is also measured.

ab109904 measures solely complex II, whereas ab109905 measures complexes II+III.
We do not offer an immunocapture activity assay for Complex III only. The reason is that we have not generated an antibody capable of immunocapturing the native enzyme.
