Abstract
Mutations at codons 248 and 249 of p53 gene showed a relatively high incidence in gastric cancer patients. Development of novel methods for the detection of codon mutations is of great importance for gastric cancer research. Studies have showed that the separation matrix can significantly influence the separation efficiency and resolution of small DNA fragments in CE. In order to achieve baseline separation of PCR-amplified products of small DNA fragments from gastric cancer tissue, linear polyacrylamides (LPA I and LPAII) were designed and synthesized in the current study. LPAI and LPAII were used as separation matrixes to separate small size fragments (less than 70 bp) of pBR322/BsuRI DNA Marker and the separation conditions were optimized. Optimum separations were performed at 25 kV in reversed-polarity mode with capillary temperature set at 15 °C. The signal of DNA fragments was detected using laser-induced fluorescence detector, with an argon ion laser as the excitation source that emits at 488 nm. A 520 nm bandpass filter was used as an emission cut-off filter. The resolution of small DNA fragments was higher when LPAI was used as separation matrix compared to LPAII, accompanied with longer migration time. The results indicated that LPAI as separation matrix was more efficient for the separation of small DNA fragments (less than 70 bp) than other LPAs. A rapid and sensitive analysis method for the separation and detection of small DNA fragments (less than 70 bp) was established in this study. The method was successfully applied to detect the mutations at codons 248 and 249 in p53 gene from gastric cancer tissues.
