The present invention relates to a compound comprising an alpha-end and an omega-end, the compound comprising on the alpha-end a reactive group Qlcapable of reacting with a functional group F1present on a biomolecule and on the omega-end a target molecule, the compound further comprising a group according to formula (1) or a salt thereof: Said compound may also be referred to as a linker-conjugate. The invention also relates to a process for the preparation of a bioconjugate, the process comprising the step of reacting a reactive group Q1of a linker-conjugate according to the invention with a functional group F1of a biomolecule. The invention further relates to a bioconjugate obtainable by the process according to the invention. In a preferred embodiment, the invention concerns a process for the preparation of a bioconjugate via a cycloaddition, such as a (4+2)-cycloaddition (e.g. a Diels-Alder reaction) or a (3+2)-cycloaddition (e.g. a 1,3-dipolar cycloaddition).

The present invention relates to an antibody comprising a GlcNAc-S(A)x substituent, wherein S(A)x is a sugar derivative comprising x functional groups A wherein A is independently selected from the group consisting of an azido group, a keto group and an alkynyl group and x is 1, 2, 3 or 4, wherein said GlcNAc-S(A)x substituent is bonded to the antibody via CI of the N-acetylglucosamine of said GlcNAc-S(A)x substituent, and wherein said N-acetylglucosamine is optionally fucosylated. The invention also relates to an antibody-conjugate, in particular to an antibody- conjugate according to the Formula (20) or (20b), wherein AB is an antibody, S is a sugar or a sugar derivative, D is a molecule of interest, and wherein said N- acetylglucosamine is optionally fucosylated (b is 0 or 1). The invention further relates to a process for the preparation of a modified antibody, to a process for the preparation of an antibody-conjugate, and to said antibody-conjugate for use as a medicament. In addition, the invention relates to a kit of parts comprising an azide-modified antibody and a linker-conjugate, wherein said linker-conjugate comprises a (hetero)cycloalkynyl group and one or more molecules of interest.
