Provided herein is a method of producing a protein comprising a target-specific extravesicular domain (TED) of an extracellular vesicle (EV) surface protein comprising modifying a polynucleotide comprising a nucleotide sequence encoding the extravesicular domain (ED) of an EV surface protein by a mutagenesis method within at least one modified region within the ED amino acid sequence with a length of 3-20 contiguous amino acids flanked by regions of the wild-type ED sequence at its N-terminus and C-terminus, to incorporate a target binding site within the ED, thereby producing a repertoire of polynucleotides encoding a variety of TEDs, each comprising a different target binding site, and selecting a TED specifically recognizing a predetermined target, and producing the protein comprising the selected TED.

Target-specific extracellular vesicles

The present invention provides a multivalent immunoglobulin or part thereof binding specifically to at least two cell surface molecules of a single cell with at least one modification in at least one structural loop region of the immunoglobulin determining binding to an epitope of the cell surface molecules wherein the unmodified immunoglobulin does not significantly bind to the epitope, its use and methods for producing it.

Multivalent immunoglobulins

A specific antigen-binding member (ABM) comprising a specific antigen-binding moiety and an antibody Fc region comprising a CH2 domain, which is engineered for a cysteine substitution at position 108 and/or 113, wherein numbering is according to the IMGT, and wherein the antibody Fc region does not comprise an antigen-binding CH3 domain; and an ABM conjugate (ABMC) comprising the ABM and at least one heterologous molecule covalently conjugated to one or both of the cysteines at positions 108 and 113 of the CH2 domain.

Cysteine engineered antigen-binding molecules

Libraries of immunoglobulins which each have one or more amino acid modifications in at least one structural loop region of such immunoglobulins, where the modified loop region specifically binds to an epitope of an antigen to which an unmodified immunoglobulin does not significantly bind.

Synthetic immunoglobulin domains with binding properties engineered in regions of the molecule different from the complementarity determining regions

The invention provides for a domain-exchanged antibody comprising a light chain (LC) composed of VL-CH3, and a heavy chain (HC) comprising VH-CH3-CH2-CH3, wherein the VL-CH3 of the LC is dimerising with the VH-CH3 of the HC thereby forming a domain-exchanged LC/HC dimer comprising a CH3LC/CH3HC domain pair, and means and method for producing the same.

Domain-exchanged antibody

The present application relates to a method of preparing a genetic package displaying oligomers of modular antibody domains binding to a target and to a scaffold ligand as well as to vectors and libraries of genetic packages produced thereby. The invention further relates to methods of selecting suitable linker sequences for use in such oligomer display.

Display of binding agents

A method for engineering an immunoglobulin having a variable domain and at least one modification in at least two structural loops of the immunoglobulin and determining the binding of the immunoglobulin to an epitope of an antigen, where the unmodified immunoglobulin does not significantly bind to said epitope, comprising the steps of providing a nucleic acid encoding an immunoglobulin having at least two structural loops, modifying at least one nucleotide residue of each of the structural loops, transferring the modified nucleic acid in an expression system, expressing the modified immunoglobulin, contacting the expressed modified immunoglobulin with an epitope, and determining whether the modified immunoglobulin binds to the epitope.

Method for engineering immunoglobulins

A method of engineering immunoglobulins which each have one or more amino acid modifications in at least one structural loop region of such immunoglobulins, where the modified loop region specifically binds to an epitope of an antigen to which an unmodified immunoglobulin does not significantly bind.

The present invention relates to a method of preparing a genetic package displaying oligomers of modular antibody domains binding to a target and to a scaffold ligand as well as to vectors and libraries of genetic packages produced thereby. The invention further relates to methods of selecting suitable linker sequences for use in such oligomer display.
