Hi, Shiqing,
In my opinion, it is not good idea.
If you want to optimize the protein buffer than you could look at
"thermofluor" method of protein buffer optimization.
BTW, have you tried seeding?

Hi everyone,
I wonder if I can add PEG or Li2SO4 into protein sample for new
screen? Because optimization seems no good result, initial crystal
was got in Bis-Tris, PEG8000, Li2SO4. If it is OK, then what's the
concentration of PEG or Li2SO4?
Best regards,
Shiqing
