Abstract

The invention discloses a nucleic acid encapsulating reagent and an application thereof. The nucleic acid encapsulating reagent provided by the invention consists of 3-10 parts by mass of agarose, 1-5 parts by mass of saponin and 2-6 parts by mass of hydroxy propyl cellulose. The invention also discloses a target material detection device, wherein the target material detection device is obtained by embedding primers and a probe for detecting a target material in a reaction device by virtue of the nucleic acid encapsulating reagent. The invention also discloses a Zika virus detection device, wherein the Zika virus detection device is obtained by embedding a primer ZIKV-F as shown in a sequence 1, a primer ZIKV-R as shown in a sequence 2 and a probe ZIKV-P as shown in a sequence 3 in the reaction device by virtue of the nucleic acid encapsulating reagent prescribed in any one of previous claims. The invention has an important application value for detecting the target material with the application of a nucleic acid sequence-based amplification technology. The invention has great application and popularization value for detection of Zika viruses and for prevention and control of related diseases.

Description

technical field [0001] The invention relates to a nucleic acid encapsulation reagent and its application. Background technique [0002] Zika virus (ZIKV) is a virus transmitted by the bite of an Aedes mosquito. In 2015, Brazil discovered the first case of Zika virus infection, and then the epidemic continued to ferment until a large-scale Zika virus outbreak broke out, which quickly spread to more than 30 South American and African regions. So far, more than 1.5 million people have been infected with Zika virus. On February 2, 2016, the World Health Organization held an emergency meeting and decided to list the spread of Zika virus as a global public health emergency. The Chinese Health and Family Planning Commission announced the "Diagnosis and Treatment Plan for Zika Virus Disease" (1st Edition, 2016) on February 3, 2016. Six days later, my country confirmed the first case of imported Zika virus infection. So far, my country has confirmed Multiple imported cases. At the ...
