[ccp4bb] Help with reducing crystal mosaicity

2007-07-09 Thread Mary Fitzgerald
Help please! I'm looking for some new ideas. I have crystals that come out of a sitting drop with a mixture of sodium cacodylate at pH 6.5, magnesium acetate and MPD for the well solution. The MPD concentration is sufficient to act as a cryoprotectant. Currently, I directly freeze these crysta

Wow, thanks. I'm going to try to answer most of the questions I've received in one message as I'm overwhelmed by the quick multitude of responses. As I stated earlier, I haven't collected any room temperature data, yet. So, I don't know the unfrozen mosaicity. It is very possible that the cry

Kumar and Joe- I'm not sure if this helps but I always purified my oligos prior to crystallization. Originally, I would order them with the trityl-group on and purify then on a reverse phase HPLC column and used TFA to cleave on column. Although towards the end of the project, I just ordered the

[ccp4bb] CCP4i problem on RHEL5
