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 298K
