Embodiment 2
[0109] 1 case of influenza A virus positive sample and 1 case of influenza B positive sample were tested with this kit, the results are as follows figure 1 As shown, both samples are positive for the corresponding channels, indicating that the present invention can effectively detect influenza A and B influenza virus samples, and can correctly type.
Embodiment 3
[0111] Add different concentrations of UNG enzymes to the system: concentration 1 (4.0U / / μL), concentration 2 (6.0U / / μL), optimal concentration (5.0U / μL), at 1×10 4 The products containing dU in copies / mL were amplified as templates. The results showed that the optimal concentration of UNG enzyme had no amplification curve, indicating that 5U / μL of UNG enzyme could eliminate no more than 1×10 4 Copies / mL of the product pollution, play the role of anti-pollution, the test results are as follows Figure 2-3 shown.
Embodiment 4
[0113] Set up 4 different combinations of DNA polymerases, adding Taq enzyme + Tth enzyme (combination 1), Taq enzyme + Vent enzyme + Tth enzyme (combination 2), Taq enzyme + Vent enzyme (combination 3), and only Containing 4 combinations of Taq enzyme (combination 4), comparative detection of influenza A / B positive samples, comparative detection results are as follows Figure 4-5 shown. from Figure 4-5 It can be seen from the results that when Taq enzyme, Vent enzyme and Tth enzyme are added to the system at the same time, the amplification effect of the reaction system is the best.
