R6G-ddATP was used as a dideoxy fluorescence substrate to establish the single base end extension (SNaPShot)-gel fluorescence method for the rapid detection of the genotypes of three high-risk human papillomaviruses (HR-HPV) (HPV quality control products were used as as samples, and R6G-ddATP dideoxy fluorescence reagent was used as substrate. Firstly, HPV was amplified by using universal primers to obtain the first round of amplified products, which were purified and used as templates for subsequent SNaPShot reactions. Then, specific one-step extension primers were used to perform SNaPShot reaction to generate R6G-fluorescence-labeled DNA extension products. The product was subjected to agarose gel electrophoresis, the results of which were observed under a Gel Imager, and the HPV genotyping was done with different one-step extension primers. Each sample was tested three times and the results were compared with DNA sequencing results.The preferred annealing temperature for SNaPShot reaction is 55 ℃. ThreeThe R6G-ddATP/SNaPShot-gel fluorescence method for the micro-detection methods of three HR-HPV genotypes was successfully established and can be used for rapid detection of |
