Crystal cryoprotectant
Webure 7). The concentrations of sugars, salts and cryoprotectant (e.g. glycerol) increase, while the volume of the unfrozen fraction decreases. The increase in osmotic strength causes an efflux of water from the cells. Slow cooling is needed in order to allow sufficient efflux of water to minimize the chance of intracellular ice formation. Webto cryo-protect your mother liquor. Put your crystal in the cryoprotectant for a minute or so and mount in a loop. Collect a large oscillation angle image. with a small oscillation angle range. Use 5 degrees (most data from protein crystals would be collected with 1 degree oscillations or less). If the crystal
