How to disrupt tetrameric coiled coil proteins?

We work with a heterodimeric protein which interacts through a coiled coil
domain. During the final purification by gel filtration the protein
appears to 
agregate into greater than dimer forms. I am looking for something to
include in the gel filtration buffer which will disrupt trimer and
tetramer structures and allow purification of the dimeric form?

Any help is greatly appreciated.
