Hi,
can you give a bit more information...
Can you concentrate the protein easily to a higher concentration,
let's say 2-3 times from what you have now, without precipitation?
What is the buffer of your protein stock solution at the moment?
At what temperature and what precipitant are you using?

Hi all
Any advice on how to get bigger crystals from
conditions that give showers of tiny crystals? I am
getting small pretty looking individual crystals but
they are too small and they don't seem to grow. In
fact, in some instances if left for a couple of days
they actually dissolve. I have fiddled around with
mother liquor volume, protein concentration as well as
drop volume (I am using hanging drop method) but none
seem to make any difference and I always get the same
tiny crystals. I think I might try microseeding but I
haven't tried that yet.
Any suggestions or tricks would be welcome
Careina.
