1VAPOR DIFFUSION, SITTING DROP6.5293The 12 mg/ml (0.95 mM) protein in the base buffer (100 mM NaCl, 0.5 mM TCEP, 20 mM HEPES pH7,5) was crystallized at 20 ??C in 30% PEGM5K, 0.2 M NH4SO4, 0.1 M MES pH 6.5, in vapor diffusion sitting drop method. Final concentration of 3% DMSO and 1 mM SGC-CBP30 (IUPAC name: 8-(3-chloro-4-methoxy-phenethyl)-4-(3,5-dimethyl-isoxazol-4-yl)-9-(2-(morpholin-4-yl)-propyl)-7,9-diaza-bicyclo[4.3.0]nona-1(6),2,4,7-tetraene) was added to the concentrated protein immediately prior to setting up the crystallization plate.
