[ccp4bb]: protein-dna complex

[W.M. B.]

Hi there:

I am crystallizing a protein-dna complex.  The diffraction from one direction is very good. when the crystal turns 90 degree, it has streaking diffraction.  I can't get a very good dataset in order to solve the structure.

The crystal is good-looking like the cubic ice. I'm tring to crystalize the complex from different conditions. Is there any other way to improve the diffraction? Any suggestion would be greatly appreciated.
