Embodiment 1
[0034] Isothermal Amplification Detection of HPV18 Virus
[0035] 1) The specific components of the recombinase-dependent constant temperature amplification reaction reagent are as follows:
[0036]
[0037]2) Prepare two tubes of reagents according to the reaction system in Example 1, and add HPV18 forward primer, reverse primer and fluorescent probe to the system. The two tube systems are respectively numbered as reaction tube No. 1 and reaction tube No. 2 , Then, add 2ulhela cells to No. 1 reaction tube, add 2ul human genomic DNA to No. 2 reaction tube as a negative control, and make up the system to 20ul with sterile water.
[0038] Forward primer (biotin marker): 20pmol
[0039] Reverse primer: 20pmol
[0040] FITC-labeled probe 15pmol
[0041] 3) After mixing, put the No. 1 reaction tube and No. 2 reaction tube into a 37°C constant temperature water bath for reaction, take out the reaction tube after 20 minutes, and denature at 95°C for 10 minutes. Put the two rea...
Embodiment 2
[0043] General PCR amplification detection of HPV18 virus
[0044] 1) The specific ingredients are as follows:
[0045]
[0046] 2) Prepare two tubes of reagents according to the reaction system in Example 2. The two tube systems are respectively numbered No. 1 reaction tube and No. 2 reaction tube. Then, add 2ulhela cells to No. 1 reaction tube, and add 2ul of human genomic DNA was used as a negative control, and the system was made up to 20ul with sterile water.
[0047] Forward primer (biotin marker): 4 pmol
[0048] Reverse primer: 4pmol
[0049] 3) Set the amplification conditions on the RCR amplification instrument as follows:
[0050] 95°C———15min94°C——30s; 55°C——30s; 72°C——45s72°C——10min
[0051] (40 cycles)
[0052] 4) Detection:
[0053] Put the two reaction tubes into the two airtight devices of the present invention respectively, cover the screw caps, and then squeeze the outer wall of the solution storage room, the result shows that there is a C line (qua...
