Indirect elisa method detects PRV antibody, and operating procedure is as follows: being purified with recombinant baculovirus expression of the invention PRgB albumen is coated with elisa plate, carries out square matrix titration, determines every 0.5 μ g of hole coating, 4 DEG C overnight.Then 37 DEG C of 1%BSA are used Close 1h.The diluted serum to be checked of 50 μ L100 times is added in every hole after washing, is incubated for 1h.50 μ L10000 are added in washing 3 times, every hole The sheep anti mouse or rabbit igg of diluted HRP label again, 37 degree of incubation 1h.Tmb substrate solution, color development at room temperature are added after washing 10min.50 μ L2mol/LH are added in every hole2SO4Stop bath terminates reaction, measures OD450Value.The result shows that immune the present embodiment The subunit vaccine of preparation, in addition to PBS group, all groups of generation PRV specific IgG antibodies at 14,28,42dpi, and Reach peak value at 42dpi.In addition, the mouse IgG antibody titre of inoculation gD-IgG2aFc and gB-IgG2aFc is above inoculation gD With the mouse (as shown in Figure 4) of gB.The subunit of the above results confirmation, AC-2-PRVgB and AC-2-PRVgB-IgG2aFc preparation Vaccine can effectively induce the atopic antibody for generating and being directed to APPV.Obviously, the PRV specificity that gB-IgG2aFc immune group generates IgG antibody is apparently higher than gD or gB immune group.Exempt from these results indicate that Antigen Fusion to IgG2aFc can be effectively facilitated body fluid Epidemic disease reaction.
2. body generates specific cell immunoreaction detection
(1) sterile taking-up mouse spleen is set after cleaning in the plate for filling incomplete RPMI-1640, is transferred to sterile homogenate In device, add a little incomplete 1640, be lightly ground, add incomplete RPMI-1640 and mix, filters removal tissue through cellular filter Fragment.Gentle aspiration filtered fluid enters in 15ml centrifuge tube, and 1000rpm is centrifuged 10min.Supernatant is abandoned, the sterile 8.3g/L of 5ml is added NH4Cl, static 5min (removal red blood cell), 1000rpm is centrifuged 10min.Supernatant is abandoned, full RPMI-1640 washing is cannotd be used up, 1000rpm is centrifuged 10min.Supernatant is abandoned, precipitating is suspended with complete 2.5mlRPMI-1640 (containing 10%FBS).Cell count, platform are expected Indigo plant dyeing, it is desirable that cell activity should be 95% or more.Adjusting cell concentration is 1 × 106/mL.12 orifice plates, every hole are added after mixing 500μL.The gB albumen of each sample purifying, canavalin (positive control) and culture solution (negative control) stimulation, and every kind of thorn Sharp object does 3 repetitions;12 porocyte culture plates are placed 37 DEG C, 5%CO2It is cultivated in incubator for 24 hours, is then centrifuged for harvest supernatant. IFN-γ and IL-4 protein expression water in supernatant are detected respectively with commercialization mouse IFN-γ and IL-4ELISA detection kit Flat, kit uses double crush syndrome.
The result shows that the IL-4 concentration of four subunit vaccine immune groups is apparently higher than IFN-γ.Furthermore gB-IgGFc exempts from The IL-4 concentration of epidemic disease group is apparently higher than that (Fig. 5, wherein left figure is the variation of IL-4 concentration, right figure in three processing groups in gD or gB group For the concentration variation of IFN-γ in three processing groups).These statistics indicate that, PRVgD the or gB albumen for connecting Fc can significantly promote Into cell immune response.
(4), the subunit vaccine of recombinant baculovirus AC-2-PRVgB and AC-2-PRVgB-IgG2aFc preparation is in mouse On attack malicious Protection
In order to assess suitability of the mouse IgG 2aFc segment as potential molecule adjuvant, all equal intranasal infections of mouse 100LD50PRVGX street strain.During monitoring, the protective rate of difference group is as shown in Figure 6.After attacking poison, gB-IgG2aFc group Protective rate is apparently higher than gB group.The mouse of immune gB-IgG2aFc all survives, without any clinical symptoms;Immune gD-IgG2aFc Mouse survival rate be 83%;The mouse survival rate of immune gD is 50%;The mouse survival rate of immune gB-IgG2aFc is 67% (as shown in Figure 6).These statistics indicate that PRVgD the or gB albumen of recombinant baculovirus expression can be effectively protected mouse from PRV infection.In addition, gB can achieve optimal protecting effect with merging for IgG2aFc segment subunit vaccine.
The above is only a preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art For member, various improvements and modifications may be made without departing from the principle of the present invention, these improvements and modifications are also answered It is considered as protection scope of the present invention.

Claims (10)

1. the recombinant baculovirus transfer vector containing porcine pseudorabies virus gB protein gene, which is characterized in that believed with GP67 Number peptide-gB-His label is that foreign gene is inserted into the restriction enzyme site between the BamHI of baculovirus transfer vector and EcoRI respectively Between place and XbaI and HindIII at restriction enzyme site;
The gB is the gene for encoding the gB albumen of C-terminal transmembrane fragment missing;The gB of the coding C-terminal transmembrane fragment missing The nucleotide sequence of the gene of albumen is as shown in SEQ ID No.1.
2. the construction method of recombinant baculovirus transfer vector described in claim 1, which comprises the following steps:
(1) using PRV genome as template, the gB segment of PCR amplification C-terminal transmembrane fragment missing;
(2) the gB segment that C-terminal transmembrane fragment lacks is connect with carrier is carrier and obtains the recombinant vector containing gB;
