Analysis of Duck Hepatitis B Virus (DHBV) by Real-Time PCR Method (CAT#: STEM-MB-3572-LGZ)

Introduction

The duck hepatitis B virus (DHBV) was the first hepatitis B virus identified from an avian host. It is a member of the Hepadnaviridae family of viruses. All members of this family display similar genomic organization and replication strategies and cause species-specific infections that result in either transient (acute) or persistent infection. <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.
