MSH: Semisynthetic conjugates of various toxic molecules, including RADIOACTIVE ISOTOPES and bacterial or plant toxins, with specific immune substances such as IMMUNOGLOBULINS; MONOCLONAL ANTIBODIES; and ANTIGENS. The antitumor or antiviral immune substance carries the toxin to the tumor or infected cell where the toxin exerts its poisonous effect.,NCI: An antibody linked to a toxic substance. Some immunotoxins can bind to cancer cells and kill them.,NCI: Agents comprised of various toxic molecules (Radioactive Isotopes and Bacterial or Plant Toxins) conjugated with specific immune substances (Immunoglobulins, Monoclonal Antibodies, and Antigens) that targets affected cells allowing incorporation of the toxin into the cells.
