remove polysaccharide from protein prep?

[Pin Xu]

Greating,

Could anyone tell me how to separate protein from soluble polysaccharide?
Recently I tried to purify a protein from 100,000 g supernatant of pollen
homogenate by ammonium sulfate precipitation. However, it seems that 
protein can be co-precipitated by polysaccharide (or liopsaccharide?).

Please send your kind reply to me via e-mail: pxu at wsuaix.csc.wsu.edu

Thanks,
