Hello Zhou, How sure are you about the space group of the solution? Any signs of twinning or t-NCS? Best, Sudipta. On Mon, Aug 20, 2018, 7:36 PM SUBSCRIBE CCP4BB Zhu Qiao < jasonqia...@gmail.com> wrote: > Hi All > > My protein is dimer both in protein buffer and crystallisation reservoir, > whi

Hi All My protein is dimer both in protein buffer and crystallisation reservoir, which is confirmed by calibration column Supderdex 200 10/300 increase. The crystal can diffract to 3 and the space group was determined to be P212121. The solvent content and Matthews coefficient shows 1 copy,
