Background:  Human metapneumovirus (hMPV) is an enveloped negative single-stranded RNA virus (ss (-)RNA) of the family Paramyxoviridae. It was isolated for the first time in 2001. HMPV is present as two genetic lineages, hMPV A and hMPV B. Human metapneumovirus causes upper and lower respiratory tract infections, symptoms very similar to respiratory syncytial virus (RSV). Human metapneumovirus has a worldwide distribution and it is one of the most common causes of lower respiratory infection in young children. Reinfections appear to be common. Co-infection of human metapneumovirus with influenza virus or RSV can occur.

Description:  ViroReal® Kit Metapneumovirus uses is a real-time PCR for the qualitative detection of the nucleocapsid protein gene of human metapneumovirus (hMPV) strains lineages hMPV A and hMPV B. Our carefully designed primers and probe ensure 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 Metapneumovirus was validated with the ABI® 7500 Fast Real-Time PCR System (fast cycle parameters are not supported, Thermo Fisher Scientific), and was also tested with Mx3005P® (Agilent), qTOWER3G (Analytik Jena), MIC instrument (bio molecular systems), LightCycler® 480 II (Roche) and cobas Z 480 Analyzer (Roche). It is also compatible with other real-time PCR instruments which detect and differentiate fluorescence in the FAM and Cy5 channel (e.g. QuantStudio 5 / 6 / 7 (Thermo Fisher Scientific)).

Frequently Asked Questions:

The kit qualitatively detects RNA of human metapneumovirus (hMPV) lineages A and B by targeting the nucleocapsid protein gene.
The kit is validated for RNA extracted from respiratory tract samples, including nasopharyngeal swabs.
An artificial RNA internal positive control (IPC) is added during extraction and detected in the Cy5 channel to monitor extraction efficiency and PCR inhibition.
The limit of detection (LoD95%) is approximately 10.8 copies of hMPV RNA per reaction.
Specific primers and probes were designed and validated; no cross-reactions with other common respiratory viruses or bacteria were observed.
BactoReal® , MycoReal® , ParoReal ® and ViroReal® Kits run with the same thermal cycling conditions.
