The use of vapor equilibration to achieve cryoprotection of thaumatin crystals. All crystals were mounted on the diffractometer directly from the vial as described in §2. (a, b) Crystals mounted directly from the growth drop and equilibrated in the vial over (a) the well solution for 45 min or (b) well solution (diluted to 80%) + 35%(w/v) methanol for 9 min. (c, d) Crystal soaked for 2 min in well solution + 10%(w/v) EG and equilibrated in a vial over (c) the same solution for 2 h or (d) well solution + 30%(w/v) EG for 45 min. |
