METHOD OF SAMPLE PREPARATION FOR URINE PROTEIN ANALYSIS WITH CAPILLARY ELECTROPHORESIS

摘要

Processes are provided for pretreating body fluid compositions and subsequently analyzing the pretreated body fluid compositions for analytes of interest. Processes for penetrating the compositions include providing size exclusion gel having a molecular weight fractionation range or a molecular weight exclusion such that the size exclusion gel is capable of excluding or fractionating the analytes of interest, and then causing the composition to contact the size exclusion gel in order to separate the analytes from low molecular weight composition components which interfere with the separation and analysis of the analytes of interest. Processes for analyzing pretreated compositions include electrophoretic methods such as capillary zone electrophoresis which involve the separation and detection of analytes of interest.
