Figure 3. Single-strand conformation polymorphism (SSCP) results of the polymerase chain reaction (PCR) product in denaturing polyacrylamide gel electrophoresis, visualized by silver nitrate staining: (A) PCR products of the SS genotype with ~236-238 bp and LL genotype with ~241-243 bp in SSCP gel; (B) Schematic of the adenine numeric repeat shown by number in single strand oligonucleotide bands or different alleles.
