Embodiment 2
[0072] Such as figure 1 As shown, an aminoglycoside drug-related gene 12srRNA gene mutation detection kit equipped with the primer composition described in Example 1 includes: a box body 1 with a box cover, a baffle 3, two sponges 2, four One test tube with distilled water 4, four test tubes with PCR reaction master mix 5, one test tube with positive quality control 12s rRNA gene A1555G mutant plasmid 6, one test tube with positive quality control 12s rRNA gene A1555G wild plasmid 7, One test tube 8 containing positive quality control 12s rRNA gene C1494T mutant plasmid, one test tube 9 containing positive quality control 12s rRNA gene C1494T wild plasmid, two test tubes 10 containing internal control gene detection primers, three containing 12s rRNA Test tube 11 of gene A1555G detection primer, three test tubes 12 containing 12s rRNA gene C1494T detection primer. Wherein, the baffle 3 is placed in the box body 1, and the box body 1 is divided into two independent cavity part...
Embodiment 3
[0075] The operation method of the kit described in the above-mentioned embodiment 2 is:
[0076] (1) Sample processing and nucleic acid extraction
[0077] Use a commercial DNA extraction kit to process the sample. For specific operations, refer to the kit instruction manual. The concentration and purity of the extracted DNA need to be measured with a UV spectrophotometer. The DNA OD 260 / OD 280 The value should be between 1.8 and 2.0, and the concentration should be between 5 and 50 ng / μL. If the quality of the sample DNA is unqualified, it should not be used for detection. It is recommended that the nucleic acid extraction should be performed again if the quality of the sample DNA is lower than 5ng / μL, and if it is higher than 50ng / μL, it should be properly extracted. Dilute to the specified concentration range, and it is recommended to test the extracted DNA immediately, otherwise, please store it below -20°C, and the storage time should not exceed 6 months. The kit qual...
