  • Patent number: 9017536
    Abstract: An object of the present invention is to provide a method for measuring hemoglobin that enables short-time, high-accuracy measurement of hemoglobin, in particular stable hemoglobin A1c, which is used as a diagnostic indicator of diabetes mellitus, and an electrophoresis apparatus that is suitably used in this measurement method. The present invention provides a method for measuring hemoglobins using electrophoresis, which includes: using a migration path having an inner surface coated with a cationic substance to be immobilized on the inner surface or a migration path having an inner surface made of a cationic material; and using a buffer solution containing a water-soluble polymer having an anionic group as an electrophoresis buffer solution.
