I have several proteins which have pI>7. So, at neutral pH values and room temperature, I get precipitates. Thus, I dissolved my proteins in 6 GHCl to prevent precipitation and lowered the pH. But now, I cannot run them on gel, they remain attached to the wells. I am looking for a suitable protocol.
Also I came across several native PAGE procedures, but I want to perform native PAGE, since I know I have several oligomeric states. That might be the next step for me.
SDS-PAGE for proteins which have pI>7
