[Comparative urine protein analysis using SDS electrophoresis and isoelectric focusing].

Abstract

Urinary specimens of 156 patients were examined simultaneously by SDS electrophoresis and isoelectric focusing (IEF). Simultaneous separated protein test mixtures may help to a rapid orientation on the isoelectric points and molecular weights of the urinary proteins. The SDS electrophoresis as well as the IEF make possible a safe proteinuria typing, whereby both methods have specific advantages.
