IDENTIFICATION AND QUANTITATION OF HUMAN URINE PROTEINS BY CAPILLARY ELECTROPHORESIS

Capillary electrophoresis, as a fully automatable, powerful analytical technique, has the potential for use in clinical laboratories for sep aration and identification of protein types in normal and abnormal hum an urine specimens. Abnormal urine specimens containing previously ide ntified proteins, anion-exchange resin treatment and addition of known components were used to identify and determine migration times of the peaks found in the electropherogram of human urine. The correlation c oefficients between capillary electrophoresis and the currently used m ethod of high-resolution agarose gel electrophoresis for Bence Jones p rotein and albumin were found to be 0.95 and 0.93, respectively.
