Information

Nucleic acid testing (NAT) is the method of choice for detection and quantification of a wide range of micro organisms. Primerdesign manufactures and supplies high quality quantitative real-time PCR kits for the detection and simultaneous quantification of numerous significant pathogens . A copy number standard curve is provided for quantification and an the internal extraction template (DNA or RNA), controls for the quality of the nucleic acid extraction and eliminates false negative results.

The kit is designed with the broadest possible detection profile to ensure that all clinically relevant strains and subtypes are detected. Target sequences are selected by working with data from key opinion leaders in the field. Multiple sequence alignments and unprecedented real-time PCR expertise in design and validation ensure the best possible kit.

Details of the target and priming specificity are included in the individual handbooks above.

Packaged, optimised and ready to use. Expect Better Data.

Molecular detection of abortive agents (Brucella spp, T. gondii, N. caninum, Schmallenberg virus, Leptospira spp. Chlamydiacae, BDV and BTV) was carried out on the samples taken from the fetus and two lambs with neurological symptoms. DNA extraction was executed with a Maxwell® 16 Cell and Tissue DNA Purification Kit (Promega Italia Srl, Milan, Italy). The DNA purity was checked by NanoDrop2000 (ThermoFisher Scientific, Waltham, MA, USA). The mix was prepared using the Genesig Advanced Kit (Genesig, York House, School Lane, Chandler’s Ford, UK), according to the manufacturer’s instructions, and Real-Time PCR was performed (QuantStudio™ 7 Pro Applied Biosystems, CA, USA).

quantitative PCR was performed on CSF samples for the detection of Neospora caninum and Toxoplasma gondii using N caninum Nc5 marker genomic sequence assays and Genesig T gondii repeat region, respectively. Assays were performed by Langford Vets Diagnostic Lab on a Qtower3 (Analytik Jena, Germany) following a laboratory‚Äźvalidated thermocycling protocol.
