A titer may be used to prove immunity to disease. A blood sample is taken and tested. If the test is positive (above a particular known value) the individual has immunity. If the test is negative (no immunity) or equivocal (not enough immunity) you need to be vaccinated. When do you ...
The comparative study of the human tumor cell line HEp-2 and rat liver for the detection of antinuclear and antinucleolar autoantibodies by the indirect immunofluorescence technic in routine screening test demonstrate that, taking titer and staining pattern into account, both substrates are able to ...
Hepatitis C infection is diagnosed with several blood tests. The hepatitis C antibody test checks for antibodies (immune particles) that fight the virus. A "non-reactive" result means that antibodies to the virus are not detected. A "reactive" result means antibodies to the virus are present, ...
03ml. Blood samples were collected for serologic evaluation and immunogenicity test before inoculation and at 1; 3,6, 12, 30 months after vaccination. 15 dogs produced high titer antibodies against rabies virus at 1 month after vaccination 66% of degs had high antibody titer at 30 months post...
Carbon clearance test, lyphocyte transformation test and TNF induction and it s titer assay test were used to evaluate the immunological activities ofwater soluble polysaccharidesfrom P. 采用碳粒廓清试验、淋巴细胞转化试验以及肿瘤坏死因子 (TNF)的诱生及其活性检测试验 ,观察阿魏侧耳水溶性多糖的免疫活性。
The titer of concentrated retrovirus was measured by a retrovirus titer set for real-time polymerase chain reaction (PCR) (TAKARA Bio Inc.) and cryopreserved at − 80 °C until use. Retroviral transduction Viral transduction was performed on RetroNectin®-coated plates according to the ...
In addition, the viral titer needs to be as high as possible to ensure that the cells are infected with highly efficient viral particles. Moreover, the efficiency of viral particles drastically drops by almost 50% if repeatedly freeze-thawed. This is overcome by snap-freezing single-use of ...
In relation to IFA, a 0.6 kappa index of agreement was obtained. COBAS-ANA concentrations increased according to IFA titer and greatest COBAS-ANA responses were obtained with pure or mixed homogeneous patterns and centromeric patterns. Analysis of COBAS-ANA response to particular antigenic ...
The viral titer was determined in a 96-well plate according to the manufacturer's instructions. A multiplicity of infection (MOI) of 1 was defined as the amount of adenoviral vector necessary to positively transfect 100% of cells after 48 h as determined by GFP fluorescence. For the pcDNA6.2...
Up to 20% of serum samples from HI have been reported to have a positive ANA IIF test, the majority of them due to the presence of anti-dense fine speckled 70 (anti-DFS70) antibodies. Monospecific anti-DFS70 antibodies represent a biomarker that can be used to discriminate AARD patients...
