1	VAPOR DIFFUSION, SITTING DROP	6.8	293	Commercial thaumatin from Thaumatococcus danielli (Sigma-Aldrich) was resuspended in Milli-Q water to a concentration of 40 mg/mL. Sitting drops were made by mixing 4 uL of protein solution and 2 uL of reservoir solution [50 mM N-(2-Acetamido)iminodiacetic acid(ADA) pH 6.8, 600 mM potassium sodium tartrate and 20 % (v/v) Glycerol] and equilibrated against 500 uL of reservoir solution at 293K.
