For example, Immunotoxins have been developed by fusing antibodies to diphtheria toxin. Antibodies home the toxin to specific cells, overexpressing the antigens and the toxin kills the target cells. Many of these toxins have receptors on certain cells. However, the receptor-binding ability of such toxins remains largely unutilized.enBIOSCIENCES AND BIOENGINEERINGThesis
