| 1 | 8.5 | 287 | Compound C52 (50 mM in DMSO) was added to 8 mg/ml MER protein to the final concentration of 2.5 mM. The mixture was rocked at 277 K overnight and further concentrated to about 35 mg/ml. Crystals were grown by mixing 2 microliters of MER inhibitor solution and 2 microliters of reservoir solution (100 mM Tris-HCl pH 8.5, 3.64 M NaCl) at 287 K using the hanging-drop vapor-diffusion method. Crystals were cryo-protected with a solution composed of glycerol, ethylene glycol, glucose, and fructose., VAPOR DIFFUSION, HANGING DROP, pH 8.50 | |
