Product Description

Product Description

Introduction

This kit is only suitable for the qualitative detection of gladiolus Burkholderia in food. The toxicity test needs to be carried
out in accordance with the national standard "GB4789.29-2020 Food Microbiology Inspection-Gladiolus Burkholderia (Pseudomonas
cocovenenans subspecies) Inspection". Principle

Based on Real Time PCR technology, primers, fluorescent probes and other reagents required for the specific gene of gladiolus Burkholderia are used, and the sample to be tested is added to carry out the amplification reaction. During the amplification process, the fluorescent probe binds to the target gene fragment, which can be decomposed by Taq enzyme and produce a fluorescent signal. At this time, the fluorescent quantitative PCR instrument can recognize the fluorescent signal, and draw the corresponding real-time amplification curve according to its strength changes, and then determine whether gladiolus Burkholderia is detected.

 

How to use?
1. Sample pretreatment 1) Preparation of sample enrichment solution template DNA: a) For food samples, such as fresh Tremella, rice and flour products and other foods, aseptically weigh 25g (mL) of sample and place it in a sterile homogenizing bag containing 225mL GVC enrichment solution (take 1g of fresh Tremella sample, cut it into pieces with scissors, and add it to a sterile homogenizing bag containing 20mL GVC enrichment solution), beat it with a slapping homogenizer for 1 min~2 min; or place it in a sterile homogenizing cup containing 225mL GVC enrichment solution and homogenize it at 8000 r/min~10000 r/min for 1 min~2 min. If the sample is in liquid state, oscillate and mix well. Place the above sample enrichment solution at 36±1 for 20 h~24 h; b) Take 1 mL of the above enrichment solution into a 1.5 mL sterile centrifuge tube, centrifuge at 6000 r/min for 5 min, and completely remove the supernatant; c) Add 30 μL of lysis solution to fully suspend the sediment at the bottom of the tube, tap the tube wall to eliminate bubbles, and heat at 99 for 10 min; d) Centrifuge at 12000 r/min for 15 min. The supernatant is the sample DNA to be tested. Keep it on ice and centrifuge it again if it is not used for a long time. 2) Preparation of suspicious colony template DNA: Pick suspicious colonies and fully suspend them in a sterile centrifuge tube pre-added with 30 μL of lysis solution, and then follow the above steps c) and d). 2. Sample addition and reaction 1) Take n PCR reaction tubes as required (n=1 tube of negative control + number of samples to be tested + 1 tube of positive control), take out the premix from the kit, fully melt, vortex and briefly centrifuge, add 20 μL of premix to each tube and set aside. 2) Add 5 μL of negative control, sample DNA to be tested, and positive control to the above n reaction tubes, respectively, with a total reaction volume of 25 μL. Cover the tube cap tightly, centrifuge briefly, and immediately perform PCR amplification reaction. 3) The PCR reaction system is 25 μL, take the FAM detection channel, and collect the fluorescence signal at 60°C in reaction stage 2. The specific procedure is as follows:

Reaction stage	Temperature	Time	Signal collection	Number of cycles
1	95°C	30 sec	/	1
2	95°C	5 sec	/	} 40
		60°C	30 sec

Note: Collect fluorescence signals at 60 in reaction stage 2. For multi-channel fluorescence PCR instrument, select fluorescein "FAM" as the signal collection channel, select "None" for quenching group, and select "None" for dye correction.

3. Results: In general, the test results can be directly read through the baseline and threshold automatically set by the software. If adjustment is required, it can be adjusted according to the instrument's own conditions (such as noise, etc.) and the different selected fluorescence channels. 1) Quality control: The negative control does not show an obvious S-type amplification curve or the Ct value is greater than 35, and the positive control shows an S-type amplification curve and its Ct value is less than 30. If the positive and negative controls do not meet the above conditions at the same time, the test results are invalid and should be retested or contact product technical support. 2) Result interpretation: (interpretation based on the Ct value obtained by the reaction, see the table below for details:)

Ct value			Result interpretation
≤35			Gladiolus Burkholderia positive.
35~37			It is recommended to retest. If the result Ct ≥ 37, Gladiolus Burkholderia negative, otherwise Gladiolus Burkholderia positive.
≥37			Gladiolus Burkholderia negative.
