2. Figure 1
Long PCR products amplifying mitochondrial DNA from infertile men. The 8.7-kb band represents wild-type full-length mtDNA, and smaller bands represent deletions. Lane M: 1-kb DNA ladder (Bio-Rad, Hercules, CA); lanes 1-4: four representative PCR products after 30 cycles of amplification from four infertile men.
