Sensitivity and selectivity of ricin toxin A chain-monoclonal antibody 791T/36 conjugates against human tumor cell lines.


Ricin toxin A chain (RTA) was conjugated to monoclonal antibody 791T/36, which was raised originally against human osteogenic sarcoma cell line 791T. The resultant conjugates were characterized and tested for cytotoxicity against a panel of human tumor cell lines representing a defined range of antigenicity with regard to 791T/36. Conjugates were highly… (More)
