How pure should my protein be with the NexTal CubicPhase kits?

Protein crystallization requires highly pure proteins, typically >95% (as evaluated by SDS-PAGE or gel filtration chromatography). However, crystallization in lipidic cubic phase can accommodate lower purity, and has been reported to work with samples as little as 50% pure.
