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 with inhibitors 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 298.0, VAPOR DIFFUSION, SITTING DROP
