METHOD FOR THE PRODUCTION OF ANTIBODIES IN IMMUNODEFICIENT ANIMAL INJECTED WITH HUMAN FETAL LIVER STEM CELLS

摘要

The current invention is related to a method for the production of a human monoclonal antibody from an immundeficient non-human animal, said method comprising contacting a newborn immunodeficient non-human animal with a human fetal liver stem cell (FL cell) to generate an immune transplanted non- human animal (reconstituted animal), subsequently contacting said reconstituted animal with an antigen, collecting from said reconstituted animal a human cell producing human antibody against said antigen, and isolating said antibody from said antibody producing cell.
