Method of producing human monoclonal antibodies and their use

摘要

Production of human monoclonal antibodies comprises: (a) immortalising human antibody-producing B cells with a modified Epstein-Barr virus (EBV); (b) screening the immortalised B cells for specificity to a target antigen; (c) isolating clones that produce the corresponding antibody, Äculturing the clonesÜ, and (d) recovering the antibodies from the culture supernatants. The modified EBV has a nuclear antigen 2 (EBNA2) gene that can be switched on for the immortalisation step and switched off before the antibody recovery step.
