Figure 4From: Development of an aptamer-conjugated fluorescent nanoprobe for MMP2Comparison of the tissue staining abilities of anti-MMP2 antibody and MMP2 aptamer. Normal aorta, atherosclerotic plaques, and gastric cancer tissues were stained with anti-MMP2 antibody and MMP2 aptamer. Similar staining patterns were observed. Scale bar, 100 μm.Back to article page
