[ccp4bb] Questions about antibody in crystallization

2017-06-22 Thread Cheng Zhang
Hi all, I have a naive question about antibodies. Many people used Fab fragments in crystallization. I am wondering if it is possible to use the whole IgG molecule with Fc fragment as well. Or it would be too flexible and bad for crystallization? Thanks, Cheng -- - Cheng Z

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 :-) Gert On 22-6-2017 20:39, Cheng Zhang wrote: Hi all, I have a naive questi

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. Jarrod Mousa On Thu, Jun 22, 2017 at 1:39 PM, Cheng Zhang wrote: > Hi all, > > I have a naive question about antibodies. Many people used Fab
