While I understand that you want to have protein concentration at its solubility limit, i had several proteins which can go to 60-80 mg/ml, they seems to get crystallized at 10-15 mg/ml. All you want is saturation in crystallization conditions. Dhiraj srivastava

We have one such candidate, which does not precipitate even at 80mg/ml instead forms phase separated globules in crystallization plate, which eventually hardens over a period of 1 to 1.5 months (which is florescent under UV microscope.) We tried screening at different pH, but failed to get any hits. Since we got few conditions in which the phase separated globules solidified, we focused on them and expanded with 120mg/ml protein, still there were not visible precipitates except for the phase separation. This has been a challenging target so far. We have tried with different constructs, which unfortunately are not soluble! Does POMs help in such cases? Or do you have any other suggestion.
