Humanized antibody or a functional fragment thereof comprises a heavy chain constant region with a mutation in the hinge region, particularly a mutation in the hinge region which prevents Fab arm exchange and thus generation of bi-specific antibodies.

обмен антиген-связывающими фрагментами/Fab-фрагментами

Fab-arm exchange
A physiological process that results in the reassortment of human IgG4 half-molecules. This process occurs naturally in vivo and can be mimicked in vitro. As a functional consequence of this process, Fab arms containing antigen-binding sites are exchanged between antibody molecules leading to novel binding combinations in the newly formed, bispecific antibody. The DuoBody® technology is based on this naturally occurring process for generating bispecificity.

https://ru.wikipedia.org/wiki/Антитела
При помощи протеазы папаина антитела можно расщепить на два Fab (англ. fragment antigen binding — антиген-связывающий фрагмент) и один Fc (англ. fragment crystallizable — фрагмент, способный к кристаллизации).
