The present invention provides antibodies and fragments thereof that specifically detect the complex of a specific cognate antigen-binding moiety, in particular antibodies, and its antigen. The antibodies of the present disclosure do not bind either said cognate antigen binding moiety or said antigen alone and this can be used e.g. to directly detect antigen-bound antigen-binding moieties. Further disclosed are methods for production and use of said antibodies and antibody fragments.

Complex-specific antibodies and antibody fragments and its use

Affinity ligands useful for mild elution affinity chromatography, including affinity ligands specific for immunoglobulins M, A, and E, are disclosed as are method of identifying and using such affinity ligands.

Affinity ligands and methods relating thereto

The present invention discloses novel screening strategies for the identification of binders that target the active site of enzymatic antigens. The present invention also discloses antigen-binding moieties which bind to the NS2B-NS3 Proteinase of West Nile Virus, in particular binders which bind to the active site, thereby inhibiting the enzymatic activity of the proteinase. The antigen-binding moieties of the present invention have numerous therapeutic and diagnostic applications.

Screening strategies for the identification of binders

The present invention relates to a method of identifying one or more genes encoding one or more proteins having an optimized property. In particular, the method comprises expressing a collection of genes and screening for a desired property, identifying a plurality of genes having the desired property, and replacing one or more one or more sub-sequences of each of said genes with a different, compatible genetic sub-sequence, and screening again in order to identify genes encoding proteins having an optimized property.

Protein (poly)peptides libraries

The present invention relates to synthetic DNA sequences which encode one or more collections of homologous proteins/(poly)peptides, and methods for generating and applying libraries of these DNA sequences. In particular, the invention relates to the preparation of a library of human-derived antibody genes by the use of synthetic consensus sequences which cover the structural repertoire of antibodies encoded in the human genome. Furthermore, the invention relates to the use of a single consensus antibody gene as a universal framework for highly diverse antibody libraries.
