Dear all,
I have 3 short questions about PEG solutions:
Does anyone know the best way to store crystallization screening blocks that contain PEG 3350?
Is it a good idea to freeze the PEG solutions at -80°C and thaw them before use?
Would the freeze-thaw process considerably alter the PEG chain lengths?
Thank you,
-Jerome
