The user must provide a sample suitable for crystallization taking into consideration the following points:

1 – Purity higher than 95% as assessed by SDS-PAGE or mass spectrometry. The presence of secondary bands in the gel or other contaminants will reduce your success rate.

2- A typical initial protein concentration is 10 mg / ml, but other concentrations are accepted when the Robolab staff is notified.
