Background:  Noroviruses are non-enveloped, single-stranded, positive-sense RNA viruses ((+)ssRNA), belonging to the family Caliciviridae. Strains are classified in five genotypes (GI – GV), infecting different species, including human, bovine, swine, mice and oysters. Bovine noroviruses belong to GIII. Norovirus GIII includes two genotypes (GIII.1 and GIII.2), with genotype GIII.1 represented by jena virus and GIII.2 represented by newbury-2 virus. Infection is associated with gastrointestinal manifestations such as diarrhea, villus atrophy and crypt hyperplasia of the proximal small intestine in cattle, especially in young calves.

Description:  ViroReal® Kit Bovine Norovirus is a real-time PCR for the qualitative detection of the RNA of the ORF1 of all known Bovine Norovirus (BNoV) genotypes (GIII.1 and GIII.2). Our carefully designed primers and probes ensure the highest sensitivity and specificity. The kit consists of an assay mix for the detection of the pathogen as well as a positive control and an internal positive control (IPC) system. To minimize PCR cross-contamination, the included reaction mix contains dUTP and uracil-N glycosylase (UNG).

PCR platforms: ViroReal® Kit Bovine Norovirus wurde für die Verwendung mit folgenden Geräten entwickelt: ABI® 7500 Fast Real-Time PCR System (fast cycle parameters werden nicht unterstützt, Thermo Fisher Scientific). Er eignet sich auch für andere real-time PCR-Geräte, die Fluoreszenz im FAM und Cy5 Kanal messen und differenzieren können (z.B. Mx3005P® (Agilent), qTOWER3G (Analytik Jena), MIC instrument (bio molecular systems), LightCycler® 480 II (Roche), cobas z 480 Analyzer (Roche) und QuantStudio™ 5 / 6 / 7 (Thermo Fisher Scientific)).

Assay: Optional - this product is also available as an assay-only format with primers, probe and a positive control, but without reaction mix.

Frequently Asked Questions:

The assay qualitatively detects RNA of Bovine Norovirus (BNoV) by targeting the ORF1 gene.
The assay is validated for RNA extracted from fecal samples of cattle.
An artificial RNA internal positive control (IPC) is added during extraction and detected in the Cy5 channel to monitor RNA extraction and RT-PCR inhibition.
The assay detects at least 50 target copies per reaction and shows linearity from 150 to 500,000 copies per reaction.
The assay contains only detection reagents and requires an external PCR mix, while the kit provides a complete reagent set including PCR mix and water.
BactoReal® , MycoReal® , ParoReal ® and ViroReal® Kits run with the same thermal cycling conditions.
