Hi, All, I just got a crystal and checked it can diffract.However, the resolution is low (3.1 A) and the mosaicity is about 1.1.Right now the crystallization condition is quite simple, just use the AS with several acid pH. Is there anything I can do for the next step to improve the mosaicity and then hopefully improve the resolution?Is it related to the purity of my protein?When I set up trays, I noticed that the big crystals come from the impure sample.I only got tiny crystals from one of the pure sample and it grows really slow ( ~ 1 week ). Thanks very much. Jenny
