The development of BsAb research goes through three main stages: chemical cross-linking of murine-derived monoclonal antibody, hybrid hy-bridomas and engineered BsAb. Among them, engineered BsAb has more formats than the other two, such as diabody, ScdHLX, ScZip, ScCH3, ScFab and BsIgG, etc. Compared with former murine-derived BsAbs, engineered BsAb has lower immunogenicity and stronger penetrating capacity, and currently, some of them appear suitable for clinical application in yields and qualities. Up to now, several phase I and phase II clinical studies of BsAb, for instance, some (Fab’)2 and Diabodies, have been performed. Among those BsAbs, anti-CD3/anti-tumor BsAbs is most common, they not only can activate T cell and induce CD3AK展开更多
