Onco-fetal specific monoclonal antibodies, methods of preparation and use

Patent ·
OSTI ID:6081418
A process is described of preparing a hybridoma secreting oncofetal specific monoclonal antibodies, which comprises: (a) immunizing an animal with immunizing amounts of a non-proliferating syngeneic mid-gestation fetal cell preparation; (b) isolating immunized lymphocytes from the animal; and (c) fusing the lymphocytes under appropriate fusion conditions with an immortalizing cell line to thereby obtain the hybridoma. A hybridoma cell line produces a monoclonal antibody having the following specificity characteristics: (a) immune reactivity towards rodent mid-gestation antigens; (b) immune reactivity towards human onco-fetal tumor antigens; (c) substantially no immune reactivity towards rodent late gestational fetal tissue; and (d) substantially no immune reactivity towards human normal tissue.
