1	VAPOR DIFFUSION, SITTING DROP	4	293	Crystallization screening accomplished using combinatorial crystallization strategy. Separate libraries of precipitants, buffers, and additives were combinatorially combined with protein (11 mg/mL protein in 10 mM Tris-HCL pH 7.0) in situ on the crystallization plate. Final concentrations of mother liquor: Buffer: 83 mM Sodium Citrate pH 4.0 Additives: 670 mM lithium sulfate, 8 mM L-glutamine, 8 mM L-Aspartic acid, 8 mM glycine, 8 mM trans-4-hydroxy-L-proline. Reservoir solution:Precipitant: 2 M lithium sulfate Crystals only grow on Mylar surface (many surfaces were tested).
