GST Contamination of GST-fusion proteins

Does anyone have suggestions on a method of purifying a gst-fusion protein
from contaminating gst protein without cleaving the fusion protein.  Due to
gst dimerization, many of the column purification methods I have tried (ion
exchange, gel filtration) have been unsuccessful.
