Analysis by isoelectric focusing of xanthine oxidase and NADH dependent enzymes in rat kidney.
Applied and theoretical electrophoresis : the official journal of the International Electrophoresis Society(1990)
Abstract
Ultrathin isoelectric focusing was employed for analyzing xanthine oxidase and enzymes with NADH-dependent dehydrogenase activity in homogenates of rat kidney. After isoelectric focusing the enzymes were stained with specific assays where NBT is reduced upon incubation of the gel with xanthine (oxidase stain) and NADH (dehydrogenase stain) as substrates. A good separation of renal enzymes with dehydrogenase activities was obtained by using gels containing 2 M urea and by applying the sample at the anode. In these conditions 4 main isoforms with pI 6.4, 6.35, 6.5 and 6.6 were observed with the dehydrogenase stain but we were unable to demonstrate renal xanthine oxidase (XO) which seemed to be due to precipitation at the application point.
