Recombinant protein stability - stability issue (Jun/04/2008 )

I have a recombinant protein thats 115aa long. The protein is not stable. after 10 days it loses about 15% activity and just keeps dropping. by 14 days about 40% of activity is lost. I want to stabalize this so attain at a minimum 28 days stability. Please assist with additives that may aid in stabalization (PBS buffer with protein and tween etc...)
