title: Purification of malic enzyme from Ascaris suum using NAD+-agarose.
abstract: Malic enzyme has been purified from Ascaris suum by polyethylene glycol precipitation, ion-exchange chromatography, ammonium sulfate precipitation, and NAD-agarose affinity chromatography to a specific activity of 80 units/mg (V/[E]t = 350 s-1). The preparation was shown to be homogeneous by SDS polyacrylamide disc gel electrophoresis. The procedure can be accomplished in a maximum of four days with a 74% yield.
