(ĭm′yə-nō-tŏk′sĭn, ĭ-myo͞o′-)
n.
A hybrid molecule formed by binding a toxin to a monoclonal antibody, used to destroy tumor cells.

immunotoxin (IT)

[-tok′sin]
a toxin that is attached to a monoclonal antibody and used to destroy a specific type of target cell. An example is the plant toxin ricin, which inhibits protein synthesis in tumor cells that are recognized by the antibodies to which ricin is attached.

immunotoxin

an antibody attached to a specific toxic agent that is used to destroy specific cancer cells. Although experimental at present, these so-called ‘magic bullets’ hold out great hope as a new form of cancer CHEMOTHERAPY.
