Abstract
Prolonged-action immunotoxin consisting of a conjugate in which an antibody or antibody fragment is coupled, by means of a covalent structure containing a disulfide group or a thioether group, with a glycoprotein which inactivates ribosomes and has a prolonged action obtained by the oxidation of its saccharide units which periodate ions.
