Figure 3From: Development of an aptamer-conjugated fluorescent nanoprobe for MMP2Precipitation of MMP2 protein by MMP2 aptamer. MMP2 protein in buffer containing 10% serum was incubated with the aptamer (0.2 μg/ml) overnight at 4°C. The protein was detected by immunoblotting with anti-MMP2 antibody.Back to article page
