The present invention provides a method of preparing fully human antibodies that recognize a pre-determined antigen without relying on human donors that have already been exposed to the antigen. To this end, lymphocytes from naive human donors are immunized in vitro with the antigen of interest, and cells that produce antibodies against the antigen are identified. Since the lymphocytes are immunized in vitro rather than in vivo, it is possible to control which antigen, or which part of the antigen, would be recognized by the antibody. A preferred antigen is gp120 of HIV, particularly the co-receptor binding region of gp120.
本发明提供了一种制备可识别预定抗原的全人
抗体的方法,无需依赖已接触过抗原的人体供体。为此,用相关抗原体外免疫天真人类供体的淋巴细胞,并鉴定产生抗原
抗体的细胞。由于淋巴细胞是在体外而不是体内免疫的,因此可以控制
抗体识别哪种抗原或抗原的哪一部分。首选的抗原是艾滋病毒的 gp120,特别是 gp120 的共受体结合区。
