title: Purification of exo- and endoinulinase from crude inulinase extract for the analysis of fructans.
abstract: This paper describes a technique for rapid and easy separation of a crude inulinase extract into exo- and endoinulinase from a commercially available inulinase stock (Novozym 230 from Novo Nordisk A/S) by means of non-denaturating polyacrylamide gel electrophoresis. The purified enzymes were tested with inulin. Characterization of the reaction products was done by high-performance thin-layer chromatography, size exclusion chromatography and semi-preparative reverse-phase high-performance liquid chromatography.
