Veterinary Feline leukemia virus/Feline AIDS virus (FeLV/FIV) DNA taq polymerase probe qPCR kit
Intended use:
This kit is suitable for the specific detection of feline leukemia virus (FeLV) and feline AIDS virus (FIV) in EDTA whole blood sample.
Principle:
Under the action of high-efficiency reverse transcriptase, cDNA strands complementary to RNA template were synthesized with PRIMER as starting point and RNA template as template. Choose feline leukemia virus (FeLV) and feline AIDS virus (FIV) 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, Fluorescence was emitted and detected by fluorescence PCR instrument to realize nucleic acid detection of f feline leukemia virus (FeLV) and feline AIDS virus (FIV) virus in the completely closed reaction system.
Main components:
| Component | Specification |
| PCR reaction liquid | 8 tubes |
| Positive control | 1 tube |
| Negative control | 1 tube |
Note: components in different batches of kits should not be interchangeable.

Sample requirements:
1. Sample type
EDTA whole blood
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 -70℃.
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:
| Step | Cycle number | Temperature | Time |
| 1 | 1 | 50℃ | 20min |
| 2 | 1 | 95℃ | 2min30s |
| 3 | 45 | 95℃ | 10s |
| 60℃ | 30s collect fluorescent |
FAM and VIC/HEX are selected for detection channels.
The results of interpretation:
| | FAM channel (FeLV) | VIC/HEX channel (FIV) | Result interpretation |
| 1 | - | - | Results were repoFIVrted negative |
| 2 | + | - | Results were reported FeL positive |
| 3 | - | + | Results were reported FIV positive |
| 4 | + | + | Results were reported FeLV,FIV positive |
Note: "+" means positive, "-" means negative
Positive judgment value or reference interval:
| Result | Ct Value |
| Positive | Ct≤38 |
| Negative | No Ct value or Ct value=0 |
| Gray area | 38＜Ct≤45 |
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.
