Embodiment 1

[0037] Example 1 Obtaining of Purified Recombinant Duck Parvovirus VP3 Protein

[0038] A. Extraction of viral DNA: After digesting part of the liver homogenate suspension of affected ducks, the total DNA was extracted by the phenol-chloroform method, and finally the total DNA was extracted with 50 μL ddH 2 O dissolved and stored at -20°C;

[0039] B. Design and synthesis of primers: According to the published complete genome sequence of duck parvovirus, combined with our sequencing results of multiple strains of duck parvovirus isolate VP3, a pair of primers were designed using Primer Premier 5.0 and the restriction enzyme BamHI was added and HindIII restriction site, the nucleotide sequence of F1:5'-CGGATCCAAGGAAGTCACAACGCAGGAT-3' is shown in SEQ ID No.3, and the nucleotide sequence of R1:5'-CAAGCTTGCCATCAGTCTGGTATT-3' is shown in SEQ ID No.4;

[0040] C. PCR amplification: PCR reaction system: 2×EsTaqMasterMix 10 μL, upstream and downstream primers F1 / R1 (20 μmol / L) 1 μL e...

Embodiment 2

[0045] Example 2 Assembly of Duck Parvovirus Indirect ELISA Detection Kit

[0046] Recombinant protein coating: Quantitatively measure the concentration of the purified recombinant protein, take an appropriate amount of recombinant protein and mix it in 10mL 1×carbonate buffer to make the final concentration 1.5ng / L, and then add it to the bottom of the 96-well enzyme plate , 100 μL per well. Cover with sealing film and incubate overnight at 4°C.

[0047] The kit includes the following reagents: 1 piece of 96-well ELISA plate, 20mL of 30×PBST washing solution, 10mL of 1×carbonate buffer (PH=9.6), 2.5g of skim milk powder, 10mL of GoatAnti-DuckIgG-HRP, soluble type One-component TMB substrate chromogenic solution 10mL, stop solution (3mol / LH 2 SO 4 ) 10mL, 4 sheets of sealing film. Store at 2-8°C for 6 months

[0048] The components and proportions of the coating solution, washing solution, blocking solution, sample diluent, chromogenic solution and stop solution are as fo...

Embodiment 3

[0056] The usage method of embodiment 3 duck parvovirus indirect ELISA detection kit

[0057] The specific steps of the method of use are as follows:

[0058] 1. ELISA detection procedure

[0059] (1) Coat the ELISA reaction plate with 150ng / well recombinant duck parvovirus VP3 protein, incubate overnight at 4°C, and wash the ELISA reaction plate 3 times with PBST;

[0060] (2) Seal the ELISA reaction plate with 5g / 100mL skimmed milk powder solution, at 37°C, after blocking for 1 hour, wash the ELISA reaction plate 3 times with PBST;

[0061] (3) Dilute the serum to be tested 1:10 times w / v with 5g / 100mL skimmed milk powder solution, add 100 μL to the ELISA reaction plate, and after 1.5 hours at 37°C, wash the ELISA reaction plate 3 times with PBST;

[0062] (4) Add goat anti-duck IgG-HRP to the ELISA reaction plate at 100 μL / well, and after 1 hour at 37°C, wash the ELISA reaction plate 3 times with PBST;

[0063] (5) Add 100 μL of substrate color development solution to th...

Abstract

The invention relates to the technical field of veterinary pathogeny antibody test, in particular to a duck parvovirus indirect ELISA (enzyme-linked immuno sorbent assay) detection reagent kit. The inventor firstly provides a duck parvovirus virus VP3 protein; the amino acid sequence of the protein is shown as SEQ ID No.1; the amino acid sequence expressing the protein is shown as SEQ ID No.2. Study shows that the protein has good immune response original performance, and can be used for DPV (duck plague virus) antibody detection; further, the protein is used for providing the duck parvovirus indirect ELISA detection reagent kit. The reagent kit has the advantages of high speed, high stability, high specificity and high sensitivity, can be used for fast detecting the antibody level of the duck parvovirus virus in the serum, and achieves the obvious promotion effect on the prevention and the control of the disease.

Description

technical field [0001] The invention relates to the technical field of veterinary pathogenic antibody detection and provides an indirect ELISA detection kit for duck parvovirus. Background technique [0002] Duck parvovirus is a kind of parvovirus, which mainly affects ducklings aged 1 to 3 weeks. The main clinical symptoms are diarrhea, dyspnea and soft feet. It occurs all year round and brings great economic benefits to duck breeding. Loss is one of the main diseases in duck breeding, and the morbidity and mortality are also high. [0003] Since March 2015, a disease has appeared in meat ducks in Shandong, Jiangsu, Anhui and other places in my country. It has been verified as duck parvovirus. The disease is characterized by dysplasia of duck beak and protruding tongue. For commercial ducks over the age of one day, the incidence rate of duck flocks is 10%-20%, up to 50%, and the infection rate of large flocks can reach up to 100%, but the disease does not cause the death of...
