Figure 3From: Association of diminished expression of RASSF1A with promoter methylation in primary gastric cancer from patients of central ChinaMethylation of RASSFIA in primary gastric cancer and corresponding normal tissue by MSP. Lane 3, 4 and lane 6, 7 show a representative result from a tumor and normal sample, respectively. U: amplified product with primer recognizing unmethylated sequences; M: amplified product with primer recognizing methylated sequences. Genomic DNA, methylated in vitro by CpG methylase (Sss I) was used as a positive control. Water blank was used as a negative control. The PCR products were resolved on a 8% polyacrylamide gelsBack to article page
