Hi -- has anyone had crystals that are colored in regular
(unpolarized) light? Mine are yellow, and I'm not aware of anything
in the buffer conditions that might cause this. I read online that
glutaraldehyde can turn protein crystals a golden color, but as far as
I know there isn't any of that in the well. Purified in HBS pH 7.2;
crystallized in LiCl/PEG4K/Tris pH 8. Any explanations?
Thanks!
Caitlyn
