Yes, the hinge region between Fab and Fc is highly flexible. If you look at
IgG by EM you will see many different conformations. Best to use Fab or
scFv.

The fact that the PDB holds hundreds of FABs and a handful whole ABs 
suggests to me that the latter are hard to get crystals for. So, all the 
more reason for us bioinformaticians that you, experimentalists try it :-)
