Analysis of Taura Syndrome Virus (TSV) by Real-Time PCR Method (CAT#: STEM-MB-2999-LGZ)

Introduction

Taura syndrome virus (TSV) is a shrimp RNA virus that was first described in 1992 from aquacultured shrimp in Ecuador. Since the initial outbreak, Taura syndrome disease (TSD) has spread to most shrimp-producing countries, primarily through transfers of shrimp seed and broodstock for aquaculture purposes or in frozen shrimp food products.<br />A real-time polymerase chain reaction (real-time PCR,or qPCR) is a laboratory technique of molecular biology based on the polymerase chain reaction(PCR). It monitors the amplification of a targeted DNA molecule during the PCR(i.e.,in real time), not at its end, as in conventional PCR.<br />Two common methods for the detection of PCR products in real-time PCR are(1)non-specific fluorescent dyes that intercalate with any double-stranded DNA and (2)sequence-specific DNA probes consisting of oligonucleotides that are labelled with a fluorescent reporter, which permits detection only after hybridization of the probe with its complementary sequence.
