That is a heavy PEG, and they arent such good cryo-agents. If you get
ice-rings when you test your buffer aone, try adding 15% of a much
lighter PEG (400 or 600).
Happy cryo-cooling

With that much PEG in your mother liquor, I don't
think you will need any cryosolvent. It will likely vitrify adequately
in LN2 directly from this solution. In solutions that do not contain
high concentrations of PEG or polyols, 25-30% glucose is nearly always
sufficient, and is compatible with
Hi, All,
What's the general rules for selecting cryosolvent?I got crystals in 30%
PEG4000/PEG3350, 0.2M AS and 0.1M NaAC,how should I choose cryosolvent?
Thanks.
