Two capillary electrophoretic methods were developed and evaluated for measurement of glycated hemoglobin HbA1c. Firstly, a capillary zone electrophoresis analysis is performed with a sodium tetraborate buffer of pH 9.3 as background electrolyte in a neutrally coated capillary. HbA1c is separated from HbA0 due to specific interactions of borate anions with the cis-diol pattern in the saccharide moiety of glycohemoglobin. Secondly, a capillary isoelectric focusing method, which exploits a difference in pI values of HbA0 and HbA1c, is performed with Servalyt pH 6-8 or alternatively with Biolyte pH 6-8 carrier ampholytes spiked with a narrow pH cut of pH 7.2 prepared by preparative fractionation of Servalyt pH 4-9 carrier ampholytes.
