Genetic Polymorphism of Cancer Susceptibility Genes and HPV Infection in Cervical Carcinogenesis

Representative genotyping of MDM2-SNP309 by two independent PCR assays for each allele. Lanes 1, 5, and 7: TG heterozygote. Lanes 2, 4, and 6: GG homozygote. Lane 3: TT homozygote. The wild-type (T) and the mutant (G) allele yields 121-bp and 168-bp fragments, respectively.
