I have recently discovered that it will be to my great advantage that
I freeze (at -80degC) aliquots of my protein for use over long periods
of time. I want to do the same with the protein complexed with its
high-affinity DNA 'ligand'. Has anyone had experience with
successfully deep freezing protein:DNA complexes? fyi: 'successfully"
in my case would mean crystallizing the complex for x-ray defraction
