Assalamualaikum and Good day. Does anyone here working on antioxidant enzymes such as SOD, CAT, APX, DHAR, MDHAR, GR, GPX? I desperately need a full protocol or working procedure for the above-mentioned enzymes assay (I mean the step-by-step protocol). I did refer to many journals but failed to get the full procedure. I would appreciate if any of you here can share it with me or suggest the best website to retrieve the protocol. Thanks in advance.
