Hi, A little danger this condition. I suggest you should firstly make sure they are protein crystals. I know it is very difficult. I suggest you can add proteases to the drops. If "crystals" dissolve, no problem, they are protein crystals.

See the attached pic. The current condition is PEG4000 and pH around 5. How can I improve this condition? Thanks a lot.
