Freeze-drying problem--Part 2

Worse news!  I tried redissolving the goo, including several spots on the 
side of the freeze-dryer flask, and it didn't go into solution.  All I got 
was a cloudy suspension.  Any thoughts?  Have I removed something (a 
carbohydrate--maybe a sugar alcohol) that was keeping the protein from 
becoming fully dehydrated?

Thanks,

Phil
