What is "crystallographic grade" protein?

The protein for crystallization should be homogeneous and >90% purity. The purity of protein shall be checked by HPLC or MS before crystallization. The DLS (dynamic light scattering) result is helpful but not required. The minimum amount is 10ug/ul * 300ul.
