ABSTRACT
A simple and rapid genotyping method with less-instrumentation is essential for realizing point-of-care detection of personalized medicine-related gene biomarkers. Herein, we developed a rapid and visualized genotyping method by coupling recombinase polymerase amplification (RPA) with allele-specific invader reaction assisted gold nanoparticle probes assembling. In the method, the DNA targets were firstly amplified by using RPA, which is a rapid isothermal amplification technology. Then an allele-specific invasion reaction was performed to recognize the single nucleotide polymorphisms (SNPs) site in the amplicons, to produce signal molecules that caused discoloration of gold nanoparticle probes. As a result, genotyping was achieved by observing the color change of the reaction by using naked eye without the requirement for any expensive instrument. In order to achieve rapid genotyping detection, the genomic DNA from oral swab lysate samples were used for the RPA templates amplification. In this way, a visualized genotyping from "samples to results" within 25 min was realized. Two clopidogrel related SNPs CYP2C19*2 and CYP2C19*3 of 56 clinical samples were correctly genotyped by using this rapid visualized genotyping assay. In addition, the feasibility for this pathogen genotyping method was also verified by detecting plasmid DNA containing three SARS-COV-2 gene mutation sites, indicating that this method has the potential for clinical sample detection.
