protein/DNA dyes

Does anyone know which dyes (methylene blue, congo red, etc.) can be added to 
xtallization drops to test growing crystals to see if they are protein, DNA, or 
(disappointingly) inorganic salt?  I have looked all over for this info and 
unfortunately (for me) I cannot find it anywhere.

Many thanks,
