SUBSTRATE FOR THE PURIFICATION OF BODY FLUIDS

摘要

The invention relates to a substrate for the purification of a body fluid, comprising a solid phase to which molecules of at least one oligosaccharide that can bind to one or more antibodies are covalently grafted, said solid phase carrying free aldehyde (-CHO) functions. The invention also relates to a method for producing such a substrate, the use of such a substrate in stabilising the antibody/oligosaccharide bond, and a method for purifying a body fluid, in which the body fluid is brought into contact with at least one substrate according to the invention, such as to capture antibodies present in the body fluid by means of bond(s) with at least some of the oligosaccharide molecules grafted to the solid phase.
