Thanks for all the suggestions. I forgot to mention that I had tried microseeding and it was partially successful. I am trying this while also pursuing other venues. At Florian's suggestion I have set up a free interface diffusion method and it looks very promising. I have a few free floating crys

Hi everyone, I have been issues with a particular protein. I have been close for a while, but yet so far. Rather than going from a clear drop to crystal, my protein first undergoes phase separation (large oily drops) in which one phase contains most, if not all, of the protein. This phase separat
