[ccp4bb] effective iodide conc. for SAD data

[Rajesh Kumar]

Dear All,
I have very thin crystals but diffracting. I was not able to handle them easily 
for iodide soak. I always lost the crystals during manipulation and other big 
crystals obtained after seeding doesn't even give any diffraction. I tried for 
co-crystallizing with NaI. The crystals appear only up to 20 mM in 1:2 (3ul 
drop of 1 ul protein and 2ul reservoir).Is this concentration of iodide is 
enough for SAD data  ( if it had good incorporation) ?I appreciate your help.
ThanksRajesh
