3. Instructions
Sample processing: sample processing in accordance with 《GB 4789.30-2016 National Food Safety Standard - Detection of Listeria monocytogenes》;
Experiment preparation: Dissolve the various components in the kit on ice before use, mix gently and centrifuge briefly, then place on ice for later use;
Reagent preparation: experimental reaction system (25 μL), 15 μL qPCR mixed reaction solution, 1 μL template, 9 μL sterile ddH2O
Reaction conditions: 95℃ 1min 1cycle; 95℃ 10s, 57℃ 30s 40cycles; Fluorescence channel: FAM;
4. Notes
Negative: The sample has no exponential growth curve, or has a lower amplification curve, and the Ct value is >38;
Positive: the sample has a typical exponential growth curve, and the Ct value is ≤38;
5. Preservation and transportation
1. Dissolve the various components in the kit on ice before use, mix thoroughly and centrifuge briefly and place on ice for later use;
2. In order to ensure the sensitivity of the detection, it is recommended that the qPCR mixed reaction solution be frozen and thawed no more than 3 times;
3. Sample processing, reagent preparation, and sample addition should be carried out in different areas to avoid cross-contamination;
