1 | VAPOR DIFFUSION, HANGING DROP | 9 | 293 | About 0.1 micro L of protein solution at 10 mg/ml concentration was mixed with 0.1 micro L of reservoir solution from a 70 L reservoir in 96-well Hampton 3553 crystallization plates. Initial crystals of NefSF2 sdAb19 SH3B6 could be obtained in 0.2 M potassium formate and 20% polyethylene glycol (PEG) 3350. Crystal conditions were optimized to 0.2 M potassium formate, 17.5% polyethylene glycol (PEG) 3350 and 0.35 M ammonium chloride grown by hanging-drop vapor diffusion in Linbro crystallization plates. , pH 9.0, VAPOR DIFFUSION, HANGING DROP, temperature 293K |
