Rotavirus A (RVA)Nucleic Acid Detection Kit

(PCR-Fluorescent Probe Method)

Intended use:

This kit is suitable for the specific detection of pathogenic rotavirus TYPE A (RVA) in porcine small intestine and fresh feces.

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 the pig epidemic diarrhea virus gene conservative design specific probe, the probe 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 detection of rotavirus TYPE A (RVA) nucleic acid in A completely closed reaction system was realized by fluorescence PCR instrument.

Main components:

Sample requirements:

1. Sample type:

Pig small intestine, fresh feces, etc

2. Sample collection and transportation:

Sample collection and transportation shall be carried out in accordance with NY/T 541. Samples shall be transported to the laboratory as soon as possible under refrigerated conditions to avoid repeated freeze-thaw.

3. Sample preservation:

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

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.
