WebNov 1, 2005 · Cryoprotectants employed by freeze-tolerant organisms constitute a diverse array of organic compounds, although they all share certain attributes,including low molecular mass, high solubility and permeability, stability,ready availability, and compatibility with macromolecules ( Storey and Storey, 2004 ). WebIf drops reliably freeze clear, then the solution has sufficient cryoprotection for freezing protein crystals. The choice of cryoprotectant will depend upon the crystallization solution composition. If protein crystallization conditions already contain a cryoprotectant, it is often ideal to simply increase the concentration to the appropriate ...
