Both will probably work. Expression in insect cells is most likely to work well, but will of course be more expensive and time consuming. There's also some slight possibility of getting unwanted glycosylation - which is not necessarily a problem. I've had good success expressing VHH fragments (s

[ccp4bb] expression of single chain variable fragment

Dear all, I'd like to express a single chain variable fragment (scFv) for crystallization purposes, but cannot decide whether I should do it in insect cells (let the antibody be secreted into culture medium) or bacteria (let the antibody be secreted into periplasmic space). If someone could give
