Hi Guan

How were you mounting the crystals?  In a capillary or in a cryo-loop?  If
the latter, have a careful read-through of Garman and Schneider (1997), J. 
Appl.  Crystallography 30, pp. 211-237.  And probably other papers too.
Important would be to try out various cryo-soaking protocolls.  

Good luck
