Problems with GST fusion protein

Is there anybody having experience on the purification of GST fusion
Our lab doesn't have much experience and now there has been a serious
problem of degradation of the GST fusion protein. We have tried the
protease inhibitor from Sigma and Roche, and the whole purification
process was accomplished in a 4 C cold room. But the proteolysed
products are still there.

Any suggestions are highly appreciated. Thank you all for your
