Plasmids containing sRAGE(OP) and GFP
were co-transfected to human embryonic kidney (HEK) 293 and
CHO–CD14 cell, respectively, and the overnight cell culture medium
was analyzed with ELISA. The green fluorescence-positive cells
adjusted results showed that the expression level of sRAGE(OP) in
CHO cell was 12% higher than that in HEK293 cells (Fig. 3),
