Method for Solving Non-specific Amplification Interference of Fluorescence Quantitative PCR in Gene Detection

摘要

Objective:To explore a method to solve the issue of interference in fluorescence quantitative PCR non-specific amplification for gene detection.Method:A three-step method was used for amplification,and the quantitative fluorescence signal collection process was set in the extension stage.Results:Three-step amplification has the advantages of wide application range;improved accuracy;and reduced primer design requirements.Conclusion:The interference of non-specific amplification signals was effectively avoided,the melting curve plotting process was omitted,the reaction time was shortened,and the detection accuracy was improved.
