Abstract: Monoclonal antibodies, which can be produced in vitro, against cardiac epitopes of the human My-C are produced by generating myeloma cell clones that produce such specific antibodies having epitope specificity. These monoclonal antibodies allow, among other things, the creation of an enzyme-linked immunosorbent assay (ELISA) for the specific, cross-reactivity-free quantitative determination of My-C in serum, plasma, whole blood or other body fluid. Specifically, a hybridoma cell clone producing a monoclonal antibody that detects and binds a cardiac epitope in the My-C is produced, which has no cross-reactivity with respect to the myosin-binding proteins of the skeletal muscles. The hybridoma cell line can be obtained by fusing myeloma cells with spleen cells of a test animal, in particular a mouse, immunized against recombinant My-C. The invention furthermore relates to epitope-specific antibodies produced by the hybridoma cell line, and to the use thereof.
Abstract: The present invention provides antigen binding proteins that specifically bind to Wilms' tumor protein (WT1), including humanized, chimeric and fully human antibodies against WT1, antibody fragments, chimeric antigen receptors (CARs), fusion proteins, and conjugates thereof.

Such antibodies, fragments, fusion proteins and conjugates thereof are useful for the treatment of WT1 associated cancers, including for example, breast cancer, ovarian cancer, prostate cancer, chronic myelocytic leukemia, multiple myeloma, acute lymphoblastic leukemia (ALL), acute myeloid/myelogenous leukemia (AML) and myelodysplastic syndrome (MDS). In more particular embodiments, the anti-WT1/A antibodies may comprise one or more framework region amino acid substitutions designed to improve protein stability, antibody binding and/or expression levels.
