2. Figure 1
(A) Schematic illustration of the interactions between the template and polymerase chain reaction (PCR) primers for amplification refractory mutation system analysis of Ala16Val SOD2 polymorphism (GenBank accession no. AY267901). Exons are shown as black boxes and the corresponding introns appear as lines. Fragments are not drawn to scale. (B) Primers used in the polymorphism analysis. The 3′-end of the allele-specific primers is underlined. Underlined lowercase bases indicate the introduced mismatches.
