Crystallization condition:
protein: 7.5 mg/mL in 10 mM Tris and 10 mM NaCl
Mother liquid: 0.2 M ammonium acetate, pH 7.0, 16% PEG3350, 1 uL mother liquid + 1 uL protein
The crystal was soaked in 8.625%(w/v) sodium acrylate, 2.5%(w/v) acrylamide and 0.2%(w/v) bis-acrylamide in mother liquid (0.2 M ammonium acetate, pH 7.0, 16% PEG 3350).
after soaking for over 48 hours, the crystal was transferred to 1% APS and 1% TEMED in mother liquid (0.2 M ammonium acetate, pH 7.0, 16% PEG 3350).
after 10 min, calcium chloride was added to the crystal with a final concentration of 100 mM.
