1	VAPOR DIFFUSION, SITTING DROP	7	310	Prior to crystallization, the protein at concentration of 162 mg/ml (dissolved in 50 mM Tris pH 7.4 and 20 mM NaCl) was mixed with 100 mM ketoprofen in 100% DMSO in ratio 9:1 (final ketoprofen concentration 10 mM) and incubated for several hours at 37 oC. Then, 0.2 ul of the protein solution was mixed with 0.2 ul of the well condition (24% PEG 3350, 50 mM K2HPO4 at pH 7.0). The crystallization plate was incubated at RT for 3 months, then for several days at 37 oC, and after the growth of the first HSA crystals, the plate was transferred to RT.
