Monoclonal antibodies against alpha-actinin-4 antigens, and uses therefor

摘要

Monoclonal antibodies (MoAbs or mAbs) specific for ALPHA-ACTININ-4 antigens, hybridoma lines that secrete these ALPHA-ACTININ-4 mAbs, and the use of such mAbs to detect ALPHA-ACTININ-4 antigens, particularly those expressed by cancer cells are disclosed. Chimeric and humanized antibodies based upon these anti-ALPHA-ACTININ-4 mAbs, processes for producing monoclonal, chimeric, and humanized antibodies using recombinant DNA technology, and their therapeutic uses, particularly in the treatment of cancer are also disclosed. Methods and kits for the immunodetection and immunotherapy of cells for samples which express ALPHA-ACTININ-4 antigens are additionally disclosed.
