Abstract: Here is disclosed isolated or purified monoclonal antibodies, or an antigen-binding fragments thereof, which binds to human CD3, and which comprises: a CDRH1 amino acid sequence of SEQ ID NO: 150, a CDRH2 amino acid sequence of SEQ ID NO: 151, a CDRH3 amino acid sequence of SEQ ID NO: 152, a CDRL1 amino acid sequence of SEQ ID NO: 153, a CDRL2 amino acid sequence of SEQ ID NO: 154, and a CDRL3 amino acid sequence of SEQ ID NO: 155. Also provided are recombinant polypeptides comprising said monoclonal antibody, or an antigen-binding fragment thereof, such as multivalent antibodies, including bispecific T-cell engagers. Also described are chimeric antigen receptors (CARs) for CAR-T therapy comprising any one of the monoclonal antibodies, or antigen-binding fragments thereof. Nucleic acids encoding the aforementioned antibodies, fragments, and polypeptides are also disclosed, along with therapeutic applications in the treatment of and autoinflammatory disease or cancer.

Abstract: The present invention teaches techniques for creating scans of documents that are both secure from tamper and that are assured of satisfactory image quality. In particular, a method of producing an assured document is disclosed wherein the documents digital signature is combined with the scan quality in a secure way.
