NAT.IMMUNOL. 6 271 279 2005 15696168 doi:10.1038/ni1170 CD28-Fc fusion complexed with 5.11A1 monoclonal antibody CD28-Fc fusion complexed with 5.11A1 monoclonal antibody
The monoclonal antibody 5.11A1 cross links CD28Fc dimers resulting in the formation of filaments. The assymetric unit of the filament is therefore one molecule of CD28Fc and one of Ab 5.11A1. The whole structure presented is the twofold averaged dimer Fab5.11A1-CD28Fc-CD28Fc-Fab5.11A1.
