1VAPOR DIFFUSION, SITTING DROP6.5298Sitting drop at room temperature with 0.6 ml reservoirs composed of 0.6 M to 1.0 M sodium tartrate titrated to pH 6.5. Drops composed of equal volumes of 50 mg/ml lyophilized thaumatin in water with the reservoir solution. Crystals appear after 12 hours and grow to full size over three days
