First, check to see if the precipitation is reversible upon dilution. You may just have exceeded its solubility in the buffer. Raising the pH a little to get further away from the pI may help. Adding some salt (e.g. 200-300 mM NaCl) may help as well.

Thank you Adam B Shapiro for your input. I will try it out.
