Large crystals were obtained by macroseeding with small crystals (0.06 mm x 0.08 mm) washed in macroseeding 1.4 M (NH4)2SO4, 50 mM HEPES pH 7.5 to slightly dissolve the crystal surfaces. After 3 to 4 weeks the crystals attained a size of 0.3 x 0.3 x 0.6 mm. Crystals of the selenomethionine labeled protein were obtained in a similar manner., Micro batch, temperature 278K |
