Is there an enzymatic assay for SDHA specifically, not SDH activity?
Yiming Qin Dear, could you please explain your reaction mixture?
I want to measure the SDHA activity (convert succinate to fumarate). I plan to express my mutant SDHA in e.coli, but I don't think there is an assay to measure just subunit A activity.
Here is a kit for measuring the succinate to fumarate reaction using an artificial acceptor.

Here is an article on a coupled enzyme assay:

There is also an ELISA kit in case you want to measure the amount of the protein instead of its activity:

Adam B Shapiro thank you very much Sir, for sharing such a valuable information.
Dear
Have a look on the following website. May it help
