摘要:
In one embodiment, a masked monoclonal antibody (mAb) is provided, the mAb, encoded by a nucleic acid sequence or an amino acid sequence molecule comprising a signal sequence, a masking epitope sequence, a linker sequence that is cleavable by a protease specific to a target tissue; and an antibody or a functional fragment thereof. In another embodiment, a cross-masked mAb heterodimer complex is provided, comprising a first masked mAb, comprising a first signal sequence, a first masking epitope sequence, a first linker that is cleavable by a protease specific to a target tissue, and a first antibody or fragment thereof; and a second masked mAb, comprising a second signal sequence, a second masking epitope sequence, a second linker that is cleavable by a protease specific to a target tissue, and a second antibody or fragment thereof.

摘要:
The present invention provides three unique monoclonal antibodies directed against a portion of the Wilms' tumor antigen, and methods of use therefor in detecting, monitoring and diagnosing malignancies characterized by over-expression or inappropriate expression of the WT 1 protein.
摘要:
Masking ligands for reversibly concealing the antigen-binding site of an antibody comprise epitopes of the antibody and a cleavable linker. Methods for making masking ligands comprise joining at least two copies of the epitope of an antibody to a cleavable polypeptide linker.
摘要:
Three unique monoclonal antibodies, each having an epitope located in amino acids 1-181 of the WT1 tumor protein, and the hybridomas which secrete them have been constructed. These monoclonal antibodies are useful in the detection, monitoring, and diagnosis of malignancies characterized by inappropriate expression of the WT1 protein.
摘要:
Monoclonal antibody 425 having properties particularly beneficial for anti-tumor therapy has been raised. MAb 425 antibody binds to EGF-receptors and inhibits their bioactivities. The amount of binding of the antibody to cancer cells can be increased by treatment of the cells with lymphokine preparations. Radiolabeled MAb 425 is used for treatment of EGF receptor-expressing gliomas.
