Abstract

A method for preparing an antibody-drug conjugate. The antibody-drug conjugate is formed by means of site-directed conjugation on the basis of an N-glycosylation site of an Fc region of an antibody. The method comprises: (1) providing a donor containing an oxazoline oligosaccharide, an antibody containing a GlcNAc motif, and an immobilized endoglycosidase having a glycoside transfer activity; and (2) covalently linking the activated donor containing the oxazoline oligosaccharide to the antibody containing the GlcNAc motif by means of the catalytic action of the endoglycosidase; therefore, one-step conjugation is realized. The present invention also relates to an endoglycosidase fusion protein, which comprises a covalently linked endoglycosidase, a Halo tag, and/or a His tag. The present invention also relates to an immobilized endoglycosidase fusion protein obtained by means of immobilizing an endoglycosidase fusion protein on a support, a prepacked column filled with the immobilized fusion protein, and a method for purifying an antibody conjugate by using the immobilized endoglycosidase fusion protein.

Abstract

A method for preparing an antibody-drug conjugate. The antibody-drug conjugate is formed by means of site-directed conjugation on the basis of an N-glycosylation site of an Fc region of an antibody. The method comprises: (1) providing a donor containing an oxazoline oligosaccharide, an antibody containing a GlcNAc motif, and an immobilized endoglycosidase having a glycoside transfer activity; and (2) covalently linking the activated donor containing the oxazoline oligosaccharide to the antibody containing the GlcNAc motif by means of the catalytic action of the endoglycosidase; therefore, one-step conjugation is realized. The present invention also relates to an endoglycosidase fusion protein, which comprises a covalently linked endoglycosidase, a Halo tag, and/or a His tag. The present invention also relates to an immobilized endoglycosidase fusion protein obtained by means of immobilizing an endoglycosidase fusion protein on a support, a prepacked column filled with the immobilized fusion protein, and a method for purifying an antibody conjugate by using the immobilized endoglycosidase fusion protein.
