Dear All,
I have got initial crystals in a condition with PEG 1000. The PEG 1000
stock we had in our lab was rock solid and when i heated it to about 50 degrees
for 15 to 20 minutes it became a solution. We thought the compound has got out
dated or something like that and bought a brand new bottle from Sigma and this
is rock solid too.
Is this something characteristic of PEG1000? The hit condition says its
12.5% w/v PEG 1000 but it apparently seems i could never get a powder of it.
So my question is, Can i go ahead using this melted solution form of
PEG1000 for setting up optimizations?
Thank you all in anticiaption,
Vasan
