Hi Nikolas The first thing I would try is to solubilise the protein a bit more, maybe by adding a few % (1-5%) glycerol or ethylene glycol to the growth conditions when you set up the drops.
The next thing would be to experiment with ratio (protein:precipitant) and drop size. Lastly, trial addition of detergents to conditions. Best!
