PCR Detection Kit for White Spot Syndrome Virus (WSSV) of Shrimp (Fluorescent Probe Assays)
Product Name: Real-time PCR Detection Kit for White spot syndrome virus.
Package: 50 kits/box
Indication: This kit is applicable to the nucleic acid detection of shrimp white spot syndrome virus DNA in shrimp muscle tissue The test results are for research purpose only and not for clinical diagnosis.
Main components and content:
Name | Specification | Quantity |
WSSV Reaction Solution | 1000µl/Tube | 1 |
WSSV Positive Control | 250µl/Tube | 1 |
Negative Control | 250µl/Tube | 1 |
Storage and Shelf Life:
Stored at -20±5℃,Repeated freezing and thawing ≤ 3 times, the shelf life is 12 months.
Test Method:
1. Nucleic Acid Extraction
Commercialized DNA extraction kit can be carried out for nucleic acid extraction, please follow the instruction of the kit.
2. PCR amplification
2.1 Calculate the number of test samples, take n+2 PCR reaction tubes, and add 20µl to of reaction solution to each tube.
2.2 Add 5µl nucleic acid of negative control, positive control and samples into the above PRC reaction tubes respectively, centrifuge at 8000rpm for several seconds, and put them into the fluorescent quantitative PCR.
2.3 The reaction conditions are set as:
Parameters of amplification | |||
System | Total volume is 25µl | ||
Signal collection | WSSV fluorescence signal | FAM channel collects fluorescence signal | |
Reaction Conditions of PCR | Phase | Conditions | Cycles |
UNG Process | 37℃ for 2 minutes | 1 | |
Pre-denaturation | 95℃ for 30 seconds | 1 | |
PCR | 95℃ for 10 seconds | 40 | |
60℃ for 30 seconds Set to collect the fluorescent signal at the end of this phase | |||
Result Judgement:
1. The validity judgement:
1.1 Positive Control: The Ct value of FAM channel ≤ 32, and the amplification curve has a significant exponential growth phase.
1.2 Negative Control: FAM channel has not amplification curve, or the amplification curve is straight line or slight oblique line, with no significant exponential growth phase, and the Ct value ≥ 38 or no Ct value.
2. The test result judgement:
2.1 If there is a significant exponential growth in FAM channel and Ct value ≤35, it is judged as WSSV positive.
2.2 If there is a significant exponential growth in FAM channel and Ct value between 35-38, it is judged as WSSV suspicious. The sample should be tested repeatedly. If the Ct value of the repeated test results is still between 35-38 with an significant exponential growth period, it is judged as positive, otherwise it is negative.
2.3 If the Ct value of FAM test results > 38 or no Ct value, it is judged as WSSV negative
Precautions:
1. The laboratory management shall be in strict accordance with the management specification of PCR gene amplification laboratory. The laboratory personnel must be trained professionally. The experiment process shall be conducted strictly in different areas (Reagent preparation area, specimen preparation area, amplification and product analysis area). All consumables shall be disposable after sterilization. Special apparatus, equipment and supplies at each stage of the experiment operation shall not be cross-used.
2. Please prepare the biological safety cabinet for reagent and specimen preparation stage. The Lab coat, disposable gloves and pipettor shall be carried out during the experiment.
3. Repeated freezing&thawing of reagents shall be avoided as far as possible. Before use, the reagents shall be completely thawed and centrifuged at 8000rpm for several seconds.
4. Please put the pipette used in the specimen preparation area into the container containing disinfectant and discard with the waste after sterilization.
5. After the experiment, the worktable and pipettor were treated with 10% hypochlorite or 75% alcohol or ultraviolet lamp.
