Crystallization

Crystalization Experiments
ID	Method	pH	Temperature	Details
1	MICROFLUIDIC		273	100 mg of Thaumatin from Thaumatococcus daniellii (Sigma, T7638) was dissolved in 1 mL of MiliQ water, reaching a concentration of 100 mg/mL with solutions vortexed to ensure complete dissolution. Subsequently, 200 uL of the thaumatin solution was mixed with 200 uL of 1.6 M (Na, K, tartrate) crystallization solution. A tube of the resulting mixture was placed on a rotator operating at 20 C. After an incubation period of 16-18 hr, thaumatin crystals grow to a size of 15-20 um with high density. Crystals were stored at 4 C until the experiment.
