  • Method and kit for separation of glycoproteins
    Patent number: 4269605
    Abstract: Glycoproteins, especially glycosylated hemoglobins, are separated from non-glycosylated proteins, by complexing with a dihydroxyboryl reactive agent. The resulting complex can be separated physically from the non-glycosylated protein, making possible the determination of glycosylated hemoglobin content of lysed blood; a reactive agent and a kit are described for use in such determination and as a monitor in the control of diabetic treatment. The invention can also be used preparatively to isolate glycoproteins.
