Fig. 5. GFP secretion is independent of factors present in serum. CHO cells
transiently expressing GFP were starved, labeled with
[35S]-methionine and chased for 6 hours in the presence of various
concentrations of serum as indicated. The cell lysates (C) and media (M) were
harvested and immunoprecipitated with anti-GFP antibodies. `% Sec.' denotes
the percentage of secretion.
