A composition comprising a first material and a second material, wherein said first material is cross-linkable by a first cross-linking reaction and said second material is cross-linkable by a second cross-linking reaction, wherein said first cross-linking reaction and said second cross-linking reaction are inducible by a common activator.

Site-specific modification of proteins with microbial transglutaminase (MTG) is a powerful and versatile strategy for a controlled modification of proteins under physiological conditions. Solid-phase microbead-immobilization is used to site-specifically and efficiently attach different functional molecules important for further downstream applications to proteins of therapeutic relevance including scFV, Fab-fragment and antibodies. MTG remained firmly immobilized with no detectable column bleeding and enzyme activity was sustained during continuous operation. Immobilized MTG shows enhanced selectivity towards a certain residue in the presence of several reactive residues which are all targeted when the conjugation was carried out in solution. The generation of dual site-specifically conjugated IgG1 with immobilized and MTG in solution is reported, i.e. site-specific conjugation to glutamine and lysine residues of IgG1 antibody. Site-specific glutamine conjugation with small peptides containing a lysine residue and a functional moiety is also described.

Engineered antibodies useful for site-specific conjugation by a transglutaminase are described. Also described are methods of site-specific conjugation of the antibodies, the site-specifically conjugated antibodies, and pharmaceutical compositions and uses related to the site-specifically conjugated antibodies.

The present invention relates to a method for generating an antibody-payload conjugate by means of a microbial transglutaminase (MTG). The method comprises a step of conjugating a linker comprising the structure (shown in N->C direction) (Sp.sub.1)-RK-(Sp.sub.2)-B-(Sp.sub.3) or (Sp.sub.1)-B-(Sp.sub.2)-RK-(Sp.sub.3) to a Gln residue comprised in an antibody, wherein (Sp.sub.1) is a chemical spacer or is absent; (Sp.sub.2) is a chemical spacer or is absent; (Sp.sub.3) is a chemical spacer or is absent; R is arginine or an arginine derivative or an arginine mimetic; K is lysine or a lysine derivative or a lysine mimetic; B is a linking moiety or a payload; and wherein the linker is conjugated to the Gin residue comprised in the antibody via a primary amine comprised in the side chain of the lysine residue, the lysine derivative or the lysine mimetic. Further, the invention relates to antibody-linker conjugates, antibody-drug conjugates and linker constructs comprising an RK motif.
