Figure 3.
Knockdown of MMP-2 gene expression in AF cells using RNA interference. Real-time RT-PCR (left) reveals greater than 95% knockdown of mRNA levels relative to a nonsense control for 2 out of the 5 shRNA constructs tested (F and G). An ELISA-based protein assay (right), however, shows effective sustained knockdown on the protein level for 4 out of the 5 constructs (E, F, G, and H).
