Objective To compare the advantages and disadvantages of the amplification refractory mutation system -polymerase chain reaction (ARMS-PCR) with restriction fragment length polymorphism polymerase chain reaction(RFLP-PCR) technology, then explore its application in detection and analysis of single nucleotide polymorphism (SNP). Methods By using ARMS-PCR and RFLP-PCR the polymorphisms of the MMP-2 in cervical cancer and the normal-control group were analyzed. The research sites were-1306 C/T.The final result was verified by DNA sequencing. Results The results of amplified used ARMS-PCR showed that the genotypes of the SNP site in MMP-2 gene promoter were CC, CT, TT, and the DNA fragments were corresponding with the results of DNA sequencing. Conclusion ARMS-PCR technology has the advantages of lower cost time-saving simple operation and reliable results, while has a high value for research of SNP.
