Problems solved by technology

The preparation of antibodies is not only time-consuming but also time-consuming. Generally, it takes at least 2-3 months to prepare antibodies with low specificity (polyclonal antibodies), and it takes longer to prepare antibodies with high specificity (monoclonal antibodies).
At the same time, this detection condition is very restrictive, and multiple samples cannot be detected at the same time, so large-scale detection cannot be performed.
In addition, the biggest disadvantage of this method is that it cannot quantitatively analyze Wolbachia

Embodiment 1

[0023] Embodiment 1: Quantitative determination of Wolbachia (Wolbachia) in midgut, salivary gland, ovary tissue of Aedes aegypti artificially transfected type B Wolbachia (Wolbachia)

[0024] 1. Acquisition of mosquito tissue samples containing Wolbachia: use CO 2 Anesthetize the mosquito to be tested (Aedes aegypti mosquito artificially transfected with Wolbachia type B), dissect and separate the mosquito tissue (midgut, salivary gland, ovary) to be tested with a needle under a dissecting microscope, and use STE buffer The isolated tissue was rinsed three times and then placed in 50 μL STE buffer. The STE buffer solution belongs to the prior art buffer solution, and its formula is 100mM NaCl, 10mM Tris-Cl, pH 8.0 and 1mM EDTA, pH 8.0.

[0025] 2. Extraction of Wolbachia genome in tissue: put 50 μL STE buffer containing mosquito tissue in a homogenizer, grind for about 45 seconds, add 2 μL protein kinase K (Proteinase K) (10 mg / mL ), place the reaction solution at 55°C for 30...

Abstract

The invention discloses a primer for quickly and quantitatively detecting Wolbachia in tissues of a mosquito and a reagent box and a method thereof. According to the invention, different tissues containing Wolbachia are separated and obtained to extract Wolbachia genomic DNA; and then the Wolbachia DNA is subjected to Real-time PCR (Polymerase Chain Reaction) detection by using a specific PCR primer of Wolbachia. The realization of the invention is beneficial for quickly and quantitatively analyzing a large quantity of tissue samples containing Wolbachia, so that the distribution of Wolbachiain the tissues of the mosquito can be conveniently monitored in a large territorial scope on a large scale.

Description

Technical field: [0001] The invention belongs to the field of biotechnology, and in particular relates to a primer for rapid quantitative detection of Wolbachia in mosquito body tissues, a kit and a method thereof. Background technique: [0002] Wolbachia is a symbiotic microorganism widely distributed in arthropods, and it may be the most abundant group of insect symbiotic microorganisms. It is distributed in Coleoptera, Diptera, Hemiptera, Homoptera, Hymenoptera, Lepidoptera and other insect species. It uses vertical transmission as its basic mode of transmission among host generations. It exists stably in the germ cells of the host, is transmitted to the offspring of the host through egg cells, and can regulate the reproductive activities of the host through various methods such as cytoplasmic incompatibility, feminization and andricide. These regulatory functions promote its widespread spread within the host population. [0003] Cytoplasmic incompatibility (CI) is the...
