We are currently using oligomycin A to inhibit ATP synthase while looking at oxidative phosphorylation however I am wondering if we should also be using other oligomycins (B, C etc) in order to see complete inhibition of this complex.
As you place the question the answer would be. Not needed if you achieve total inhibition of ATP synthase using oligomycin A. But perhaps you are not achieving total inhibition?
I have been using the oligomycin with a Seahorse analyser so it is hard to tell if it is completely gone. It seems to inhibit oxygen consumption quite well however I do not seem to be getting the expected increase in extra cellular acidification which is why I thought there may be another one required.
