Product Description

Product Description

Introduction

This kit is based on loop-mediated isothermal amplification (LAMP) technology and is used for rapid detection of Salmonella in
food. The results can be directly interpreted with the help of chromogenic indicators. Principle

Two pairs of special primers and Bst DNA polymerase with strand displacement activity are used to circulate a circular single-stranded structure at the primer junction at both ends of the template. The primers successfully combine with the template and perform strand displacement amplification reaction, achieving constant temperature Continuous and rapid amplification is carried out under certain conditions (60-65°C). When a color indicator is added to the reaction, the color difference between negative and positive results is significant, and the results can be interpreted directly through the color change.

 

Product features: 1. Quick and easy: Mix the enzyme, primer and other reaction components and then dry them to increase the stability of the reagents. It reduces the solution preparation steps when using it, which is more convenient. The entire detection reaction can be completed within 1 hour; 2. High specificity: Design multiple primers using multiple independent regions on the target gene sequence to ensure the high specificity of the amplification reaction; 3. High sensitivity: The minimum detection limit reaches 14 CFU/Test; 4. Simple interpretation: Add a color indicator before the reaction, observe the color change of the reaction solution by naked eyes after the reaction, or track the change of the fluorescence spectrum through a fluorescence monitoring instrument to interpret the results. It is intuitive and convenient, and can effectively avoid aerosol contamination caused by opening the lid after the reaction.

How to use?
1. Sample pretreatment A. Preparation of sample enrichment solution template DNA: a) Pipette 1 mL of enrichment solution into a 1.5 mL sterile centrifuge tube, centrifuge at 6000 r/min for 5 min, discard the supernatant, suspend and wash the precipitate 1-2 times with 50 μL sterile ultrapure water, centrifuge at 6000 r/min for 5 min, and completely remove the supernatant; b) Add 30 μL lysis buffer, fully suspend the bacteria, tap the tube wall to eliminate bubbles, and heat at 99 for 10 min; c) Centrifuge at 12000 r/min for 15 min. The supernatant is the crude DNA, which can be transferred to a 0.2 mL sterile centrifuge tube and can be stored for a long time at -20. B. Preparation of template DNA for suspicious colonies: Pick suspicious colonies, suspend them in a sterile centrifuge tube containing 30 μL lysis buffer, and then follow the above steps b) and c). 2. Reconstitution of negative and positive controls and dry powder reagents A. Reconstitution of negative and positive controls: When used for the first time, add 80 μL of ultrapure water to the positive control and negative control freeze-dried powders, mix them after dissolving, and store them at -20°C for later use. B. Reconstitution of dry powder reagents: Take out the freeze-dried powder reagents, cut n test reagent tubes as required (n = number of samples to be tested + 1 tube of positive control + 1 tube of negative control), add 20 μL of reconstitution solution to each tube, and dissolve them completely for later use. 3. Amplification reaction A. Turn on the instrument that can provide constant temperature conditions and set it to 63 for standby; B. Add 2.5 μL of color indicator to each of the n reaction tubes that have been added with the reconstitution solution; C. Add 2.5 μL of the sample nucleic acid to be tested, the negative control, and the positive control to the n reaction tubes that have been added with the reconstitution solution, and cover the lids tightly; D. Place all the reaction tubes in a constant temperature instrument and react at a constant temperature of 63 for 50 min. 4. Result interpretation: After the reaction is completed, it is recommended to place the sample on a white background under sufficient natural light to observe the results. The negative control test reagent tube is light orange, and the positive control test reagent tube is fluorescent green. The test sample reaction tube is interpreted as a control. If any result of the positive and negative control reaction tubes does not match the above situation, the test result is invalid and should be retested or contact product technical support.
