Figure 5
Examples of solution change using an automated linear gradient equilibration as described. Three different crystal pots are shown. In each panel, the intact crystals shown on the right were gradient-equilibrated and then transferred to a crystal pot containing the target solution. (a) α-Lactalbumin crystals, 0 → 25% glycerol over 50 min. (b) Thermolysin crystals, ∼2 M ammonium sulfate → water over 15 min. (c) Lysozyme crystals, 8% NaCl → 3% NaCl over 40 min. The cracked crystals shown on the left were directly transferred to the same pot with the target solution containing the gradient-equilibrated crystals. Hence, direct transfer to the target solution damages the crystals.
