insoluble GST-fusion protein

Dear all,

I am having a bit of a problem with a GST-fusion protein which is
insoluble.  We have tried sarkosyl treatment to solubilize and found 
that it does solubilize in 0.25%-0.5% but we cannot get it to bind to 
the resin!!!  We have tried adding triton X100 (1%-5%) but still no 
fusion - although the GST  binds ok!!

Any suggestions would be most appreciated!

Thanks in advance,
