Product Content Description:

 1. Applications

1.1 Principle

This kit can be used inqualitative analysis of Enterobacter sakazakii contamination based on the principle of Loop-mediated isothermal amplification coupled with fluorochrome coloration reaction.

1.2 Graphy


2.DNA template Sample preparation 

2.1 Notice before dispose the sample

2.1.1 Pre-enrichment culture is used as the sample for detection of Enterobacter sakazakii;

2.1.2The storage of sample solution: the sample solution can be stored at 0-4 for 24 h and at -20for long term. Repeated freeze-thaw should be avoided.

2.2 The general pre-enrichment culture

2.2.1 Add 1mL of pre-enrichment culture into a sterilized 1.5mLtube and centrifuge at 10,000 r/min for 2 min. Remove the supernatant completely but not convolute the precipitate;

2.2.2 Resuspend the strain in 80μL DNA extraction solution;

2.2.3 Vortex to mix completely then incubates the mixture at 95 for 10 min;

2.2.4 Centrifuge for 2 min at 10,000 r/min;

2.2.5 The supernatant is the DNA template. Transfer the supernatant into a fresh 1.5mL tube which can be stored at -20 for long term.

2.3 The presumptive positive colony

2.3.1 Pluck the presumptive positive colony and transfer to 80μL of DNA extraction solution;

2.3.2 Vortex to mix completely then incubates the mixture at 95 for 10 min;

2.3.3 Centrifuge for 2 min at 10,000 r/min;

2.3.4 Repeat 2.2.5.

2.4 The dairy pre-enrichment

2.4.1 Shake the pre-enrichment culture gently and allow the mixture to stand for precipitating;

2.4.2 Insert the pipette tip to the beneath 2-3 cm of surface overlay and transfer200μL culture into a fresh 1.5mL tube;

2.4.3 Centrifuge for 2 min at 14,000 r/min and remove the supernatant completely but not convolute the precipitate;

2.4.4 If the tube wall is full of adhering drops, shot spin for 10-15s. If not, skip to the next step;

2.4.5 Resuspend the strain in 80μL DNA extraction solution;

2.4.6 Vortex to mix completely then incubates the mixture at 95 for 10 min;


2.4.7 Centrifuge for 2 min at 14,000 r/min. The mixture will be separated into three layers including white sediment, transparent middle layer and white floating substance. Transfer the transparent middle layer to a fresh tube carefully as to not inject floating substance and the sediment (the transparent middle layer is the DNA template).
