Analysis of Necrotizing Hepatopancreatitis Bacterium (NHPB) by Real-Time PCR Method (CAT#: STEM-MB-2968-LGZ)

Introduction

Necrotizing hepatopancreatitis (NHP) is a severe bacterial disease affecting penaeid shrimp aquaculture. NHP is caused by the gram-negative, pleomorphic, obligately intracellular NHP-bacterium (NHPB) that targets the hepatopancreas tissue of shrimp. NHPB is classified as an α -proteobacterium and is related to members of the Rickettsia.
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.
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.
