  • Cytotoxic products formed by covalent bonding of the A chain of ricin with an antibody and the process for their preparation and use
    Patent number: 4340535
    Abstract: Carcinostatic products are formed by coupling, by covalent bonding, the A chain of ricin with an antibody which is capable of selectively recognizing a given antigen at the surface of cancerous cells. Such products can be made by the formation of a disulphide bridge between the free thiol group in the A chain of ricin and an immunoglobulin or immunoglobulin fragment into which a thiol group or an activated disulphide group has been introduced. The A chain of ricin and the immunoglobulin are carefully purified before use.
