[ccp4bb] low expression and aggregation of protein

[m zhang]

Dear All,
Recently I am trying to express a glycoprotein in Drosophila S2 cells. However, 
the expression yield is every low and most of the protein expressed aggregate. 
I was suggested making new constructs. But I am wondering if anyone here can 
give me some suggestions to improve it beyond that since I am new to 
glycoprotein? All your input will be greatly appreciated!
Regards,
Min
