protein complex on denaturing gel

if your protein is a 120kda and you're picking up a band that's roughly
250 kda, i'd say that it is most likely a hi.molec.wt aggregate of your
protein.  how soluble/insoluble is your protein??  if your protein is
pretty cranky and not that soluble, then that's what i would venture the
other band to be.  this idea would be more credible if you found bands
that are in the multiples of 120 i.e a 360 kda band etc...i would figure
that's easy enough to find out by running a lower percentage gel, although
i dont know how low you could go...hope this helps...cheers...
