(a) Dependence of the unit-cell volume of β-galactosidase crystals on cryoprotectant concentration. The triangles denote crystals at room temperature and the circles denote flash-cooled crystals at low temperature. (b) Dependence of the unit-cell volume of thermolysin crystals on cryoprotectant at room temperature (triangles) and at low temperature (circles). |
