摘要：
The invention relates to a method for analysis by capillary electrophoresis of glycated haemoglobins comprising at least one globin chain comprising a glucose residue bound to the amino acid in the N-terminal position, contained in a biological sample, said method comprising using a buffer composition comprising at least one compound which is capable of specifically complexing glucose residues of one or several glycated haemoglobin(s) and of providing said glycated haemoglobin(s) with several negative electric charges at an alkaline pH. By way of example, this compound may be 3,4- or 3,5- dicarboxyphenylboronic acid, preferably 3,5- dicarboxyphenylboronic acid. Said method may in particular be used to separate and assay haemoglobin HbA1c present in a biological sample optionally comprising other haemoglobins, in particular other minor fractions. The invention also concerns buffer compositions for use in said analysis, as well as kits for the analysis and for the assay of glycated haemoglobins by capillary electrophoresis.
