Dear Crystallographers,

Please help us in figuring out whether the attached crystal diffraction 
screenshot belongs to a protein crystal or that of a salt crystal. The 
cryoprotection condition was not optimized for the crystal. The crystallization 
conditions for the crystal is : 
Ammonium sulphate , lithium sulphate, Sodium Citrate buffer pH = 5.6.
