Results showed that dietary copper levels(8 mg/kg)significantly increased with performance, antibody valence to NDV in serum and CuZn-SOD activity at the early stage , ANAE+% of lymphocyte and ether extract apparent deposit rate through the whole period (P<0.01) ;
The result showed that:Compared with the control group,serum ND antibody valence,serum glucose(Glu),total protein(TP), albumin(ALB), calcium(Ca) content decreased in treatment gorup(P < 0.05).
Observation of immunity and safety in immunized pigs of wild using"O"type FMDV genetic engineering vaccine have been carried, and the increases of antibody valence in some immunized pigs have heen detected.
Meanwhile the serum agglutinin antibody valence immuned by SRBC was increased significantly (P< 0.01), and the serum hemolysin was no significantly (P< 0.05).
An indirect enzymelinked immunosorbent assay (ELISA) was developed to detect the antibody valence of DRV. The antigen was prepared for ELISA by sodium sulfate centrifugation and precipitation and its virus protein content was up to 0.7355 mg /ml.
Methods:Besides dynamic monitoring of immune antibody valence in maternal serum,the gene determination analysis was carried out for anteatal determining Rh genotypes.
The ability to inhibit IN activity depends on the antibody valence.

A weak virulent 061 pattern Y pestis strain was selectively cultivated by using the method of haematin hydrochloride The strain was obtained from the 148 patter hypertoxic and mild virulent Y.pestis strains which were isolated in Qia nghai and Jilin provinces,The biological features reminder toxicity heredity stbility and immunity of the strain have met the needs of the technical requirements as being a live vaccine as well as the pathological changes within the experiment animals The strain's protection ef...
Purified the against toxoplasma McAb (3C1), immunized rabbit and prepared polyclonal against-Id antibody (Abz). Use of M-206 adjuvant prepared vaccine of against-Id. The pig and mice -ere immunized with the vaccine at dose of 31.75mg/pig and 2.5mg/mice respectively. The antibody valence was 1:4 after immune 7 days, and in 28 days was 1:64 (IHA). Challenge with toxoplasma virulent strain (GTS) to pig and mice according to 107 and 103. Immunized pig without obvious clinical reaction, but con...
Using antigen that synthesized with ochracin A-BSA immunized Ba1b/c mice, extracting the spleen cell of the mice, and SP2/0 cell fused. Through clone and ELISA screen, set up three hybridoma cell lines (3G2, 1D12 and 2G7) of secretion against OA monoclonal antibody. Antibody valence of cell supernatant fluid, and ascites were 128, (3G2) 64(1D12, 2G7), and 10-7(3C12), 10-6(2G7) by ELISA respectively. Three strains of McAb belong to IgG. It secreted stable antibody. The sensitivity, of...
