Figure 1. PCR analysis of SOD1 gene polymorphism. One fragment of 570 bp for SOD1 wild-type (AA), two fragments of 369 and 201 bp for variant homozygous (GG); and three fragments of 570, 369, and 201 bp for heterozygous (AG). Columns show the following: M column, DL500 DNA marker; 1 and 2 columns, SOD1 wild-type (AA); 3 and 7 columns, SOD1 heterozygous (AG); 4, 5, and 6 columns, SOD1 variant homozygous (GG).
