Figure 3 RT-PCR product gel electrophoresis photograph. Five μL RT-PCR products of procollagen α2(I) and β-actin run on 1.5% agarose gel stained with EB. Lane 1 as PCR marker, lane 2 and 3 as the control for procollagen α2(I) and β-actin respectively, lane 4 and 5 SA-A 10^-6 mol/L for procollagen α2(I) and β-actin respectively, lane 6 and 7 as SA-A 10^-5 mol/L for procollagen α2(I) and β-actin respectively.
