Analysis of Yellow Head Virus(YHV) by Real-Time PCR Method (CAT#: STEM-MB-3622-LGZ)

Introduction

Yellow head virus (YHV) infects the black tiger shrimp (Penaeus monodon) – one of the world's major aquaculture species. It is a highly virulent pathogen that can cause 100% mortality within a few days of the first signs of disease in a pond.<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.
