The present invention relates to the field of diagnostics and, more in particular, to MRI activatable contrast agents and compositions thereof for the detection of nuclease activity, wherein said nuclease activity is caused by microbial infection or by nuclease activity related to cancer, particularly colon cancer or pancreatic cancer. Activatable contrast agents for MRI have been developed, wherein the oligonucleotide is flanked by a paramagnetic and a superparamagnetic agent, and thus providing magnetic quenching. Moreover, the oligonucleotide has regions that confer resistance to mammalian endonucleases and sensitivity to microbial endonucleases. When the activatable contrast agent of the invention is in the presence of microbial nuclease activity or a tumour cell nuclease activity, the oligonucleotide is cleaved, agents are unquenched, and the signal derived from the activated contrast agent is detected by MRI.

The present invention relates to an isolated antibody, which selectively binds to CLEC14A, wherein said antibody (a) comprises at least one heavy chain variable region that comprises three CDRs and at least one light chain variable region that comprises three CDRs, wherein said heavy chain variable region comprises: (i) a variable heavy (VH) CDR1 that has the amino acid sequence of SEQ ID NO. 105, preferably of SEQ ID NO: 2 or 42; (ii) a VH CDR2 that has the amino acid sequence of SEQ ID NO. 106, preferably of SEQ ID NO: 3 or 43; and/or (iii) a VH CDR3 that has the amino acid sequence of SEQ ID NO. 107, preferably of SEQ ID NO: 4 or 44; and/or wherein said light chain variable region comprises: (iv) a variable light (VL) CDR1 that has the amino acid sequence of SEQ ID NO. 108, preferably of SEQ ID NO: 6 or 46; (v) a VL CDR2 that has the amino acid sequence of SEQ ID NO. 109, preferably of SEQ ID NO: 7 or 47; and/or (vi) a VL CDR3 that has the amino acid sequence of SEQ ID NO. 1 10, preferably of SEQ ID NO: 8 or 48; or (b) comprises at least one heavy chain variable region that comprises three CDRs and at least one light chain variable region that comprises three CDRs, wherein said heavy chain variable region comprises: (i) a variable heavy (VH) CDR1 that has the amino acid sequence of SEQ ID NO: 22; (ii) a VH CDR2 that has the amino acid sequence of SEQ ID NO: 23; and/or (iii) a VH CDR3 that has the amino acid sequence of SEQ ID NO: 24; and/or wherein said light chain variable region comprises: (iv) a variable light (VL) CDR1 that has the amino acid sequence of SEQ ID NO: 26; (v) a VL CDR2 that has the amino acid sequence of SEQ ID NO: 27; and/or (vi) a VL CDR3 that has the amino acid sequence of SEQ ID NO: 28; or (c) is an antibody which can compete with antibody (a) or (b) for binding to CLEC14A. The invention further provides chimeric antigen receptors, nucleic acid molecules encoding the antibodies of the invention or the chimeric antigen receptors, vectors, cells and methods/uses of the antibodies and chimeric antigen receptors.

Methods for developing disease-related nanobodies and related products and kits are provided. The disease-specific proteins are extracellular matrix (ECM) proteins, domains or epitopes that are associated with various aspects of disease and are not present, or are present in very low quantities, in non-diseased individuals. Highly effective nanobodies capable of specifically binding to these ECM protein epitopes useful in in vivo imaging assays, the detection, diagnosis and treatment of diseases as well as monitoring therapeutic progress in a patient with a disease are provided herein.
