| 摘要 |
<p>The invention relates to a method for the analysis of glycated hemoglobins by capillary electrophoresis, said glycated hemoglobins comprising at least one globin chain including a glucose residue bonded to the amino acid in the N-terminal position and being contained in a biological sample, wherein said method includes the implementation of a buffer composition including at least one compound capable of specifically complexing glucose residues of one or more glycated hemoglobins and conveying, to said hemoglobin(s), a plurality negative electric charges having an alkaline pH. For example, said compound can be 3,4- or 3,5-dicarboxyphenylboronic acid, preferably 3,5-dicarboxyphenylboronic acid. Said method can particularly be used for separating and assaying the HbAi0 hemoglobin present in a biological sample optionally comprising other hemoglobins, in particular other minor fractions. The invention also relates to buffer compositions useful for said analysis, as well as to kits for analyzing and assaying glycated hemoglobins by capillary electrophoresis.</p> |
