We won't be able to prepare and crystallise a SelMet derivative during that time period, but we have loads of crystals sitting around. The diffraction isn't great, we see maybe 3.5 at home but might be enough to get over the line. > It will be a very difficult MR target, so we were thinking of soaking so crystals with heavy atomic compounds that we have lying around. I was wondering if people had any suggestions of compounds that people have used successfully for experimental phasing and maybe concentrations to use and soaking time. > > Cheers, > > Rhys
