CA 2347160

A method of separating hemoglobin A2 is provided which enables more precise and quicker separation of HbA2 than conventional methods. A method for separating hemoglobin A2 from a hemoglobin mixture according to a cation exchange liquid chromatography characterized that at least two types of eluents are used including an eluent (hereinafter referred to as "eluent A") for elution of faster hemoglobins than hemoglobin A0 and an eluent (hereinafter referred to as "eluent B") for elution of hemoglobin A0 and slower hemoglobins than hemoglobin A0, and that the eluent A has a pH of 4.0 - 6.0 and the eluent B is maintained at a pH of at least 0.5 higher than that of the eluent A.

L'invention concerne une méthode de séparation de l'hémoglobine A2 (HbA2) permettant de séparer HbA2 avec une plus grande précision et dans des délais plus brefs que la méthode conventionnelle. En l'occurrence, l'invention concerne une méthode permettant de séparer l'hémoglobine A2 d'un mélange d'hémoglobines par chromatographie liquide avec échange de cations, ladite méthode étant caractérisée en ce qu'elle utilise deux solutions d'élution au moins, dont une solution d'élution (appelée </= solution d'élution A >/= ) destinée à l'élution des hémoglobines éluées avant l'élution de l'hémoglobine A0, et une autre solution d'élution (appelée </= solution d'élution B >/= ) destinée à l'élution des hémoglobines éluées après l'élution de l'hémoglobine A0, et en ce que la solution d'élution A a une valeur de pH comprise entre 4,0 et 6,0 alors que la solution d'élution B a une valeur de pH supérieure d'au moins 0,5 à la valeur de pH de la solution d'élution A.
