Analysis of HumanT-lymphotropicVirus2(HTLV-2) by Real-Time PCR Method (CAT#: STEM-MB-2555-LGZ)

Introduction

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.




Principle

HumanT-lymphotropicVirus2 (HTLV-2) is an RNA virus that can cause blood cancer or other metastatic cancers after infection. HTLV-2 and HTLV-1 have 70% homology and are also distantly related to HIV (HIV-I). The virus mainly infects CD4+T lymphocytes in the body and can cause adult T lymphocyte leukemia/lymphoma and other diseases, mainly through blood transfusion, needle, sexual behavior, mother-to-child transmission, posing a threat to human health. Therefore, rapid and sensitive detection of HTLV virus is of great significance. Based on RT-PCR technology, it has high specificity. The primers are designed according to the highly conserved region of HTLV virus type 2, which will not cross-react with RNA of other viruses.

Applications

Specifically testing for human T-lymphotropic virus type 2, only for scientific purposes.

Procedure
