Figure 3From: GAPDH, β-actin and β2-microglobulin, as three common reference genes, are not reliable for gene expression studies in equine adipose- and marrow-derived mesenchymal stem cellsRepresentative ethidium bromide-stained gel electrophoresis confirmed the size of all the PCR products generated was at 183 bp for GAPDH, 63 bp for β-actin and 97 bp for B2M. First (1) lane is 100-bp DNA marker, 6 next lanes are bone marrow (1–3) and adipose tissue (4–6) samples and the last lane (7) is negative control.Back to article page
