ID	Method	pH	Temperature	Details
1	VAPOR DIFFUSION, SITTING DROP	5.5	298	The WT-TTR was concentrated to 4 mg/mL in 10 mM NaPi, 100 mM KCl, at pH 7.6 and co-crystallized at room temperature using the vapor-diffusion sitting drop method. Crystals were grown from 1.395 M sodium citrate, 3.5% v/v glycerol at pH 5.5. The crystals were frozen using a cryo-protectant solution of 1.395 M sodium citrate, pH 5.5, containing 10% v/v glycerol, VAPOR DIFFUSION, SITTING DROP, temperature 298K
