Re: [ccp4bb] Crystallization with no precipitant

2017-03-03 Thread D Bonsor
Thanks for the all the comments on/off board. Especially for papers describing this method as it may be handy if the structure is solved. The crystals are reproducible. They have started to appear after 4 days. I can accelerate it to a day using just 1.5M NaCl as a reservoir solution, though I

Dear all First of all, thanks for the replies here and off-list. I reprocessed the data to 2 A, and modeled two copies of the ligand in each of the two protein NCS molecules, without using NCS restraints for refinement. I also calculated an SA omit map and a polder map. In the end, the ligand
