Assay of glycosidase by lectin affinity high-performance liquid chromatography.

ABSTRACT

Human transferrin was incubated with sialidase and beta-galactosidase and then examined by lectin affinity high-performance liquid chromatography (HPLC). The elution patterns were changed according to the period of incubation and the amount of enzyme. This method of studying lectin affinity HPLC using human transferrin as a substrate makes possible the rapid and important detection of glycosidase activity.
