Real-time fluorescence quantification PCR detection primer for quickly identifying genotypes of duck circovirus and detection method thereof
PendingCN106065419AIdentification method is simpleImprove shortcutMicrobiological testing/measurementMicroorganism based processesFluorescencePcr method
The invention relates to a real-time fluorescence quantification PCR detection primer for quickly identifying genotypes of duck circovirus and a detection method thereof. The sequences of the primer are described as follows: an upstream primer P1: 5'-CAGATCCCCGGGCACGAGA-3'; a downstream primer P2: 5'-CCTCACCTTCAGGGATTC-3'. The detection method includes the steps of: establishing the real-time fluorescence quantification PCR method based on SYBR Green I with the primer, wherein difference of temperature of a melting curve exists due to the difference of GC content of a nucleotide in a specific gene fragment region of gene 1-type duck circovirus and gene 2-type duck circovirus which are amplified by the primer, so that infection of the gene 1-type duck circovirus and the gene 2-type duck circovirus can be directly carried out according to the difference of Tm value in the melting curve. The method can distinguish the infection caused by the duck circovirus in different genotypes just with one group of primer, thereby providing technical fundament for healthy breeding in duck breeding industry.
