Yep, solved a structure at Cu K-alpha once with the sulfur signal,
resolution 1.7A and a redundancy of 50 or so did the trick. Actually,
one of the sulphurs we found was an ordered SO4 molecule, so if you have
that in your crystallisation condition it might be a bonus...

If your crystal diffracts well and tough enough for high redundant data
collection, no HA or using sulfur in your protein will be the first
choice. Even at Cu K-alpha. I think...

Dear All,
I need some suggestions regarding the SAD phasing using home source.
What the the most commonly used HA for SAD phasing for Cu anode.
All suggestions are welcome.
Thanks.
