Hi All,
there is a condition in the JCSG+ screen (0.2M Li2SO4, 0.1M NaOAc pH 4.5,
50.0% v/v PEG-400) which forms heavy precipitate when made here in the lab.
I assume that the order of addition of compounds might make a difference,
but doesn't this suggest that there is a high probabilty for salt crystals
under these conditions? How stable can this solution be? An anecdotes/advice
appreciated.
I assume that the PEG makes Li2SO4 fall out of solution, or perhaps it is
the pH?
