Yellow Head Virus YHV Aquaculture Test Kit Pcr Test RT PCR

Yellow Head Virus (YHV) Nucleic Acid Detection Kit (RT-PCR-Fluorescent Probe Method)

 
Intended use:

This kit is suitable for the specific detection of pathogenic yellow head virus (YHV) in tissue samples such as gills, antennae glands, hematopoietic tissues and lymphatic organs of penaeus prawn.

Principle:
 
This kit uses RNA as a template and primers as a starting point to synthesize cDNA strands complementary to RNA template under the action of high-efficiency reverse transcriptase. Choose cat goblet virus gene conservative design specific probe, the probe can with primer amplification area in the middle of a specific binding DNA template, in the process of PCR extension, the circumscribed Taq polymerase enzymes from the 5 'end of fluorescent groups on the probe will be cut down, make it free in the reaction system, thereby quenching groups out of the 3' end, glow, The nucleic acid of Prawn yellow head virus (YHV) was detected by fluorescence PCR in a completely closed reaction system.
 
Main components:
 

1. Sample type

Tissue samples from prawn

2. Sample collection

Samples were collected according to SNT 1151.4-2003.

Take fresh prawn tissue as sample.

2.1 For larvae or young shrimp, whole shrimp or shrimp heads are taken as samples. To remove the head, use sterilizing scissors and tweezers to remove the eyes, breastplate, all thoracic appendages, and abdomen behind the head.

2.2 For adult shrimp, gill filaments, lymphatic organs or hemolymph were taken as samples.

3. Sample preservation

It can be stored for 24 hours at 2℃~8℃, and can be stored for a long time at -20℃.

PCR amplification and fluorescence detection (PCR detection area):

Put each reaction tube into the PCR instrument and perform PCR amplification according to the following procedures:

FAM is selected for detection channels.

Product performance index picture:

Quality control:

1. Negative control: No obvious amplification curve of FAM detection channel;
2. Positive control: FAM channel showed obvious amplification curve, Ct value ≤30;
3. The above conditions are met simultaneously in the same experiment; otherwise, the experiment is invalid and re-testing is required.

The results of interpretation

Note: The result is judged to be grey area, which needs to be rechecked. If the recheck result is Ct value < 45 is considered as positive, and no Ct value or Ct value ≥45 is considered as negative.

Product performance index:

1. Accuracy

The positive reference materials of testing enterprises were all positive.

2. Minimum detection limit: the detection limit of this kit is 10copies/μL.

3. Precision: Coefficient of variation (CV,%) of intra-batch precision Ct value is ≤5%.

4. Linear, linear correlation coefficient | r | > 0.980.
