Provided herein, inter alia, are single chain antibody binding domains (VHHs) for use in conjunction with the Assay with a Large Immuno-sorbent Surface Area (ALISSA). Engineered and affinity matured VHHs are used as affinity reagents in the ALISSA resulting in an exceptionally sensitive and precise method for the detection of toxins at miniscule concentrations. Thus, provided herein are methods as well as reagents that can be used to detect the presence of botulinum neurotoxins in quantities well below 1 pg/mL which corresponds to a lethal concentration under presumed equal distribution throughout the human body.

The present invention relates to a novel antibody against HERV-K envelope that targets a conserved region not affected by glycosylation or by native conformation, and its use in diagnostics and/or in therapy.

The invention relates to a multispecific antigen-binding molecule specifically binding to CD16A and consisting of two polypeptide chains, wherein each polypeptide chain comprises at least four variable domains from the N-terminus to the C-terminus in the order: VH_BCMA-VL_CD16A-VH_CD16A-VL_BCM

The present disclosure relates to multi-specific molecules which are capable of simultaneously binding at least two different target antigens or epitopes. The molecules comprise at least one binding domain molecule (BDM) which binds to a first target antigen or epitope, the BDM being modified for selective binding to a heterologous target, coupled to a pharmacologically active protein or peptide which is an antibody or antigen-binding fragment thereof or a non-antibody protein or peptide which binds to a second target antigen or epitope, the BDMs being coupled to a C-terminus of a polypeptide present within the pharmacologically active protein or peptide.

The present invention provides molecules, such as ISVDs and Nanobodies, that bind to PD1 and LAG3 and, optionally to human serum albumin. These molecules have been engineered so as to reduce the incidence of binding by pre-existing antibodies in the bodies of a subject administered such a molecule. Methods for increasing immune response, treating cancer and/or treating an infectious disease with such molecules are provided.

Methods for making, identifying, isolating and/or making binding proteins that contain an immunoglobulin light chain variable domain, including a somatically hypermutated light chain variable domain, fused with a heavy chain constant region, are provided. Exemplary binding proteins specific to small molecules are also provided.

The invention provides CCL14 antibodies.

The present invention concerns antigen binding proteins specifically binding melanoma associated antigen A (MAGE-A) protein-derived antigens. The invention in particular provides antigen binding proteins which specifically bind to the MAGE-A antigenic peptide comprising or consisting of SEQ ID NO: 1 in a complex with a major histocombatibility (MHC) protein. The antigen binding proteins of the invention contain, in particular, the complementary determining regions (CDRs) of novel engineered T cell receptors (TCRs) that specifically bind to said MAGE-A peptide/MHC complex. The antigen binding proteins of the invention are of use for the diagnosis, treatment and prevention of MAGE-A expressing cancerous diseases. Further provided are nucleic acids encoding the antigen binding proteins of the invention, vectors comprising these nucleic acids, recombinant cells expressing the antigen binding proteins and pharmaceutical compositions comprising the antigen binding proteins of the invention.

The invention provides novel biparatopic LRP5/LRP6 cross-reactive binding polypeptides, and more specifically novel biparatopic LRP5/LRP6 cross-reactive immunoglobulin single variable domain constructs which can inhibit Wnt signaling pathways. The invention also relates to specific sequences of such polypeptides, methods of their production, and methods of using them, including methods of treatment of diseases such as cancer.

The invention relates to antibodies, antibody fragments and binding agents that specifically recognize oligomeric tau but do not bind to monomelic tau, fibrillar tau or non-disease associated forms of tau.
