Figure 6: Agarose gel (2%) of samples of DNA in control (DMSO) and TPEN treated rats expresing TAUT in retina and β-actin as constitutive standard for semi-quantities of mRNA for the transporter. Six representative samples in two gels, 1: Molecular Weight Markers (MW); 2: negative control; 3: β-actin (0.025 μM); 4: β-actin (0.05 μM); β-actin (0.1 μM; β-actin (0.5 μM). A. 7 to 12: DMSO, TAUT (707 base pairs, bp)/β-actin (285 bp). B. 7 to 12: 5 days after with 5 nM TPEN treated, TAUT/β-actin. n = 6.
