中文Norovirus (GⅠ) RT-PCR Detection Kit
Product Name
Norovirus (GⅠ) RT-PCR Detection Kit (Lyophilized)
Size
48tests/kit, 50tests/kit
Intended Use
It is suitable for the detection of Norovirus (GⅠ) in shellfish, raw vegetables and fruits, water, feces, vomit and other specimens. Nucleic acid extraction should be carried out by nucleic acid extraction kit or direct pyrolysis method according to different specimen types.The kit is an ALL-READY PCR SYSTEM(Lyophilized), which contains the DNA amplification enzyme, reverse transcriptase,reaction buffer, specific primers and probes required for fluorescent PCR detection.

Suspicious resut, retest* |
*If the retest result of FAM channel has a Ct value ≤40 and shows typical “S” shape amplification curve, the result is interpreted as positive, otherwise it is negative.
