Seegene announced today the publication of an independent retrospective study evaluating the Seeplex® Diarrhea-V ACE (Seeplex® DV) assay. The assay was found to be sensitive, specific, convenient and reliable for the direct detection of multiple enteric viruses in one reaction from patients with gastroenteritis.

Seeplex® DV is a novel commercialized multiplex reverse transcription polymerase chain reaction (RT-PCR) assay capable of simultaneously detecting and differentiating five common viral diarrheal pathogens; adenovirus, rotavirus, norovirus genogroup I (GI) and GII and astrovirus. The assay has been approved for use in more than 30 countries accepting the CE-IVD mark, as well as Health Canada. Many laboratories and hospitals located in around 30 countries, including UK, Germany, France, Spain and Italy, use the product currently. However, the detection kit is not available in the United States and has not yet been cleared for use by the United States Food & Drug Administration.

Viral gastroenteritis outbreaks occur frequently in nursing homes and health care institutions as well as on cruise ships. The incidence of viral induced gastroenteritis has been reported to be on the increase and in certain cases can be associated with increased morbidity and mortality. Acute intestinal infection can be caused by one of several viruses, including adenovirus, rotavirus, norovirus GI and GII or astrovirus.

The authors of the study note that current molecular diagnostic technologies rely on laboratory-developed, or "home brew" tests that are expensive require advanced clinical techniques, and often test for only one infection at a time. The authors add that "the Seeplex® DV assay demonstrates several strengths as a commercial assay for use in a wider range of clinical laboratory settings
outside of a highly resourced centre."

Quantitatively measure the amplification of DNA with real-time PCR (qPCR) and droplet digital PCR (ddPCR) kits and systems, and discover automated PCR setup solutions to increase throughput. Alternative DNA amplification methods also include recombinase polymerase amplification (RPA) kits. Find the best PCR kits and thermal cyclers and purification equipment in our peer-reviewed product directory: compare products, check customer reviews and receive pricing direct from manufacturers.MicrobiologyMicrobiology is the study of microorganisms including protists, prokaryotes, fungi, and, often, viruses. Microorganisms are a useful research tool as genetic vectors and, in immunology, for antibiotic susceptibility testing, cellular biology and genetics. Microorganisms commonly grow readily in incubators with microbial culture media; this can contain chromogenic supplements to differentiate between cell lines. Estimate your culture’s density of microorganisms with colony counters, or screen and select colonies for desirable clones with automated colony pickers. Additionally, equipment is available to monitor environments for the presence of microbes and identify with microbial identification instruments.

Immunology kits and analysis systems often use techniques such as ELISA, radioimmunoassay (RIA) and immunodiffusion assays, Immunohistochemistry, and flow cytometry. Immunologists use equipment such as flow Cytometers, plate readers, plate washers and fluorescent microscopes.Point-of-CarePoint-of-Care Testing (POCT) or Near Patient Testing (NPT) products are available for urine, blood and other clinical chemistry analyses. POCT includes: blood glucose testing, blood gas and electrolytes analysis, rapid coagulation testing (PT / INR), rapid cardiac markers diagnostics, drugs of abuse screening, urine strips testing, pregnancy testing, fecal occult blood analysis, food pathogens screening, hemoglobin diagnostics, infectious disease testing and cholesterol screening.Clinical TrialsClinical Trials, an essential part of drug discovery process, assess the safety and effectiveness of a new medication or device in the pharmaceutical industry. Clinical Trials are a phased process (Phase 0, Phase I, Phase II, Phase III and Phase IV) which begins after initial preclinical testing.Clinical GeneticsMolecular Genetics covers the analysis of hereditary genetic disease and chromosomal abnormalities. Genetics can be analysed using DNA, RNA, and protein microarrays, PCR, RT PCR and DNA sequencing. Genetic equipment includes genetic workstations, thermal cyclers, cooling blocks and electrophoresis products. Diagnostic kits are used for DNA / RNA extraction and purification.
