I have been using the Baculovirus expression system for expresion of a viral
gene. Thus far all my expression and recombinant protein production work was
done in TC100-10%FCS medium. But recently I started adapting the SF9 cells to a
GIBCO serum free medium called,SF900II. With abit of toruble I could wean them
onto Sf900II(cells are now growing like wildfire!!). But Subsequently whenever 
I have done infections in these.                                     .
conditions, there is no rec. protein, even less virus production. If I seed
cells from SF900II ,but during infection replace with TC100-10% FCS ,I get good
yield of the rec.protein.
However, I would like to use the advantage of the serum free conditions for
production of rec. protein.
Can any one help with this problem???
