Introduction: ELISA is a sensitive, specific, reproducible and fast method to quantify the biological activity of antibodies. Trastuzumab is a humanized monoclonal antibody against HER2 receptors which prevents the initiation of downstream signaling pathway. Trastuzumab can be used as a positive control in the ELISA experiments for anti-HER2 antibodies. Additionaly, insufficient washing and blo...
Elderly dogs are steadily increasing worldwide as well veterinarians’ and owners’ interest in their health wellness. Aging is not a disease, but combination of changes negatively affecting the organism general immune system particular, resulting decline protection over time. The aim this study was to measure specific serum antibody titers against main dangerous widespread viral diseases prevent...
In double-transgenic mice expressing a gene construct encoding hen egg lysozyme as well as rearranged anti-lysozyme antibody genes, large numbers of anti-lysozyme B cells are present in peripheral lymphoid tissues but are profoundly tolerant. The cellular basis for this form of non-deletional self-tolerance was explored. The tolerant anti-lysozyme B cells from double-transgenic mice were found ...
A novel biosensor for immunoglobulin G (IgG) detection based on an extended-gate type organic field effect transistor (OFET) has been developed that possesses an anti-IgG antibody on its extended-gate electrode and can be operated below 3 V. The titration results from the target IgG in the presence of a bovine serum albumin interferent, clearly exhibiting a negative shift in the OFET transfer c...
Serum samples obtained from 59 persons who had acute necrotizing ulcerative gingivitis, periodontitis, syphilis, or Lyme disease were tested against Treponema phagedenis biotype Reiter, Treponema denticola, Treponema vincentii, and Treponema scoliodontum by indirect fluorescent-antibody staining methods. Although there were positive reactions for sera representing each of these study groups and...
We describe the photophysical properties of Seta-633, a commercially available near-infrared (NIR) dye, and its use as a fluorescent label to study the interaction between low-molecular-weight analytes and proteins using fluorescence lifetime as the readout parameter. In a model assay, we demonstrate that a biotinylated Seta-633 tracer binds to antibiotin with high specificity. Importantly, the...
We describe the measurement of rheumatoid factor in human sera with a rate nephelometer. The National Reference Preparation for Rheumatoid Factors is used to calibrate the assay in International Units. We used Hyland Positive Control, Level I, as a secondary standard. The standard curve is exponential, but is linear when plotted on log-log graph paper. Aggregated immune globulin (IgG) is the an...
Boston and ABC strains of mumps virus produced plaques approximately 1.0 mm in diameter in monolayers of BGM cells. The plaques were circular and either clear or target-like in form. Ricki strain virus produced plaques of similar size and form but, in addition, a red plaque was observed with this agent. The vaccine strain of mumps virus, Jeryl Lynn, produced minute clear plaques approximately 0...
