Hello,
The information you provided to us here is not enough. there are so many parameters and
so many means to optimize 2D crystal. All of which depends on what kind of protein you
are working on (membrane associated or soluble) and what kind of technique that you use
to grow your crystal (lipid monolayer, dialysis or else).
I guess unless you give us more info about your crystal otherwise it will be quite difficult
for us to help you optimize your condition.
Sincerely,
Puey
