Embodiment 1

[0037]

[0039] The EGR-03347 gene (as shown in SEQ ID NO: 2) was amplified by PCR with the protoscoria cDNA as a template.

[0041] Reaction program: pre-denaturation at 94°C for 5 min; denaturation at 94°C for 30s, annealing at 62°C for 30s, extension at 72°C for 30s, a total of 35 cycles

[0044] The results show: the size of the target fragment and the expected result are consistent with 822bp (see Figure 1).

[0049] (2) After 20min, take out and place in a 42° C. water bath for heat shock for 90s, and immediately transfer to an ice bath on ice for 5min.

[0055] Reaction program: pre-denaturation at 94°C for 5 min; denaturation at 94°C for 30s, annealing at 62°C for 30s, extension at 72°C for 30s, a total of 35 cycles

[0064] After mixing the above components, connect overnight at 4°C. The ligation product was transferred into DH5α competent cells, and the transformation steps were the same as

[0074] 3. the next day, the thalline was repeatedly ...

Embodiment 2

[0099] The experimental dogs were immunized with an equal volume of 200 μg protein content and a final concentration of 2 mg / mL QuilA solution.

[0101] The EGR-03347 group, the PBS group, and the QuilA experimental dog were injected with immune substances at two subcutaneous points on the neck respectively at 200 μg / . waived

[0107] (5) Display: add 50 μL of TMB chromogenic solution to each well, and incubate at 37° C. for 15 min.

Abstract

The invention discloses a Echinococcus granulosus 3-hydroxyacyl-CoA dehydrogenase protein and an application thereof, belonging to the technical field of immunology. The amino acid sequence of the Echinococcus granulosus 3-hydroxyacyl-CoA dehydrogenase protein is shown in SEQ ID NO: 1; the protein is obtained by prokaryotic expression of the 3-hydroxyacyl-CoA dehydrogenase, and the resulting recombinant protein After immunizing dogs, it was found that the protein can significantly increase the rate of worm reduction and inhibit the growth and development of Echinococcus granulosus segments, indicating that this protein can be used as a candidate antigen for anti-Echinococcus granulosus vaccine Research and development provide technical support and data support.

Description

Echinococcus granulosus 3-hydroxyacyl-CoA dehydrogenase protein and its application technical field The present invention relates to immunology technical field, relate to a kind of Echinococcus granulosus 3-hydroxyacyl-CoA dehydrogenase protein White. Background technique Echinococcosis granulosus (Echinococcosis) is also known as cystic echinococcosis (cystic echinococcosis, CE), Echinococcus granulosus (E.g.) is parasitic on the liver, lung, etc. An important zoonotic parasitic disease caused by the internal organs. The endemic areas of hydatid disease in my country are mainly concentrated in Xinjiang, Qinghai, Gansu, Ningxia, Tibet and other places. Hydatid disease has caused serious economic losses to my country's animal husbandry, and also seriously endangered human health. my country has listed the disease as a key prevention in the "National Medium- and Long-Term Animal Disease Prevention and Control Plan" (2012-2020). one of the animal diseases. Immu...
