title: Blotting membrane micropreparation in capillary electrophoresis to evaluate enzyme purity and activity.
abstract: A micropreparation system for proteins and peptides analyzed by capillary electrophoresis that uses a blotting membrane and an improved micro-test-plate was developed. The system is useful for enzyme diagnosis and purification. In the system, enzyme is collected in a concentrated spot on these membranes, and the activities are measured enzymatically to evaluate the resolution of the system.
