Protein purification problem - protein purification problem (Jun/12/2006 )

Hello, friends I am trying to purify a protein of 13KDa molecular weight but problem is that, this protein is contaminated with another protein having molecular weight of 14KDa. Can you please suggest any simple method to seprate these two proteins (please don't suggest any immunological method because i don't have antibodies).


HPLC should do it.
