A modified vapor-diffusion crystallization protocol that uses a common dehydrating agent

In the vapor-diffusion protein-crystallization method, a small drop containing protein sample mixed with a crystallization solution is equilibrated against a reservoir solution in a sealed chamber. Whereas the chemical composition of the crystallization solution is critical for success, the primary role of the reservoir solution is to slowly concentrate the crystallization drop in a controlled fashion. Accordingly, it might be possible to use...
