Hi all. I set up some trays of membrane protein remotely in cubic phase. I don't have ready access to them so I can't shoot/pick the crystals. Under polarising lights, some crystals appears coloured across many conditions, making me think these are salt. Is there some knowledge of inorganic chemistry that be relied to prioritise some for reproductions at my lab? Can detergents crystallise and produce colours under polarising light?
Thank you. Theresa
