Figure 8: The TR enzymatic activity of SWAP after serum-treatment. The results are presented as mean SD after three independent tests. A, B, C, D, and E indicated that anti-SjTGR serum, normal mouse serum, anti-SjTGR serum-treated SWAP, normal mouse serum-treated SWAP, and untreated SWAP. The asterisk (*) indicates the significant decrease of the enzymatic activity of SWAP after serum treatment compared with normal SWAP and SWAP treated with normal serum ( ).
