1	VAPOR DIFFUSION, HANGING DROP	8.5	293	condition 2-33 of the Morpheus crystal screen (Molecular Dimensions) at a protein concentration of 10 mg/mL from a hanging drop of 1 ml protein and 4 ml well buffer. Condition 2-33 contains 0.1 M of a carboxylic acid mixture (0.2 M sodium formate, 0.2 M ammonium acetate, 0.2 M sodium citrate tribasic dihydrate, 0.2 M sodium potassium tartrate tetrahydrate, and 0.2 M sodium oxamate), 0.1 M of a buffer system at pH 8.5 (Tris base and BICINE), and a 30% v/v precipitant mix (40% v/v PEG 500 MME and 20% w/v PEG 20000)
