Problems solved by technology

This reagent uses the principle of RT-PCR-ELISA for detection, and only uses a pair of primers and probes corresponding to the HIV gag gene, which cannot guarantee the specific binding to each subtype and the binding ability caused by possible mutations in the prime

Abstract

A nucleotide sequence for inspecting HIV virus rapidly, its method and in-vitro diagnostic reagent knit are disclosed. It's cheap, simple and accurate and has wide inspection range, and it can be used to inspect A-H sub-family and O-family of M family.

Description

technical field [0001] The invention relates to a nucleotide sequence, a method and an in vitro diagnostic kit for rapid detection of HIV virus, belonging to the field of virus molecular biology and medical biotechnology. Background technique [0002] HIV is a human immunodeficiency virus group in the genus Lentivirus of the Retroviridae family. So far, according to serological response and viral nucleic acid sequence determination, the HIV prevalence in the world can be divided into 2 types: HIV-1 type and HIV-2 type. Within the HIV-1 type, according to the homology of the env gene encoding the envelope protein and the gag gene encoding the capsid protein, it is further divided into three groups: M group (main group), O group (peripheral group) and N group. Group (new group or non-M non-O group), M group can be divided into A-J10 subtypes. Between HIV-1 and HIV-2, the nucleotide sequence has 45% homology, and there is immune cross-reaction. The early diagnosis of HIV is ...
