Some salts may also serve as cryoprotectants: malonate, formate, ammonium sulfate (at >3.5 M), lithium sulfate, and perhaps others. Anything with a flat solubility vs temperature is a good candidate. Mixing of different cryos can often have a superior protective effect to single-component cryos of the same total concentration (the "confusion principle"), so there are a lot of combinations to try. | Some salts may also serve as cryoprotectants: malonate (see Acta Cryst D59, 2356), formate, ammonium sulfate (at >3.5 M), lithium sulfate, and perhaps others.
