Figure 1From: Genetic polymorphisms of MDM2 and TP53 genes are associated with risk of nasopharyngeal carcinoma in a Chinese population Representative PCR-RFLP for different genotypes containing the TP53 Arg72Pro polymorphism site and DNA sequencing analysis. (A) M: DNA size markers; lane 1, 2, 4 and 5: TP53 72Pro/Pro; lane 6, 7 and 8: TP53 72Arg/Pro; lane 3: TP53 72Arg/Arg. (B) The PCR products with different PCR-RFLP profiles were sequenced to confirm the genotypes.Back to article page
