Dear Harvey,
Microseeding and adding 1-5% glycerol to the drops helped me when I
obtained crystals like these. Good Luck!

Dear Harvey,
I had very good results with low melt agarose and the detergent screen
(e.g. Hampton Research). In both cases, the tendency for cluster formation
as well as the diffraction power could be improved.

Dear CCP4BBers,
Recently I got a crystal which appeared in the condition
Correct, the DS Visualizer is not available for Mac OS at this point, however
various emulators such as Parallels or VMWare have been used successfully.
Without going into too much detail, there is a new version (3.0) of the
visualizer which extends even further the capabilities of our previous
Dear all,
I got a lot of salt crystals in reservior solution (well solution), which
contains 0.1 M phosphate/citrate ph 4.2, PEG200 47%, EDTA-2Na 0-22mM.
Reservior solution appears crystals from 12mM EDTA. Could someone help me to
explain why?
Thank you very much!
Yibin
The pH is too low and the EDTA is insoluble. You need to be above pH ~8.0.
Your best bet is to try another chelator.
