    Abstract
    OBJECTIVE:

    To develop a method to rapidly detect the N1 and N2 subtype of influenza virus by fluorescence real-time quantitative PCR.
    METHODS:

    According to the conservative sequences of NA gene of the N1 and N2 subtype of influenza virus, two pairs of primer and Taq-man probe were designed, respectively. Using one step RT-PCR kit to set up a duplex RT-PCR system for detecting the N1 and N2 subtype of influenza virus; the standard quantitative curve of the assay was established by using 10-fold serial dilution of in-vitro transcribed RNA, and the sensitivity and reproducibility was determined. The specificity and test for influenza virus and respirovirus were also determined by using this duplex Real-time RT-PCR system.
    RESULTS:

    The sensitivity of detecting the N1 and N2 subtype of influenza virus was 10 copies/microl, and the regression coefficient of the quantitative curve was higher than 99%. The amplification efficiency and specificity of this assay was 102.21% and 101.78% respectively. The system was capable of detecting human influenza viruses with high specificity.
    CONCLUSION:

    The detection system based on RT-PCR could be utilized to rapidly and sensitively detect the N1 and N2 subtype of influenza virus.
