Analysis of glycated hemoglobin A1c by capillary electrophoresis and capillary isoelectric focusing.
Dušan Koval et al.
Analytical biochemistry, 413(1), 8-15 (2011-02-09)
Two capillary electrophoretic methods were developed and evaluated for measurement of glycated hemoglobin A1c (HbA1c). First, a capillary electrophoresis analysis is performed with a sodium tetraborate buffer (pH 9.3) as background electrolyte in a neutrally coated capillary. HbA1c is separated
