Development of a bead-based multiplex immunoassay for simultaneous quantitative detection of IgG serum antibodies against measles, mumps, rubella, and varicella-zoster virus.
Enzyme-linked immunosorbent assay (ELISA) is normally used to quantify the amount of serum IgG antibodies against measles, mumps, rubella, and varicella-zoster virus (MMRV). However, this method is time- and material-consuming. Therefore, a multiplex immunoassay for the simultaneous quantitative detection of antibodies against MMRV was developed. In-house as well as commercially available antigens can be used, making the assay available for all laboratories. The multiplex assay is much more sensitive than the separate ELISAs and has a high specificity, and only 5 μl of serum is needed. Heterologous inhibition did not exceed 11.5%, while homologous inhibition varied between 91.3 and 97.9%. Good correlations with the in-house ELISAs for measles (R(2) = 0.98), mumps (R(2) = 0.97), and rubella (R(2) = 0.97) virus as well as with the ELISA kit for varicella-zoster virus (R(2) = 0.95) were obtained. In conclusion, the MMRV multiplex assay is a good alternative to the conventional ELISAs and suitable for use in serosurveillance and vaccine studies.

Analysis of factors associated with varicella-zoster virus susceptibility among children 0-12 years old in Taiwan.
Varicella is a highly infectious disease caused by varicella-zoster virus (VZV). The aim of this study was to explore the geographical difference of VZV antibody seroprevalence among children in private vaccination areas in Taiwan, controlling for potential factors relating to varicella susceptibility. 2604 related Products with: Analysis of factors associated with varicella-zoster virus susceptibility among children 0-12 years old in Taiwan.

A simple and cheaper in house varicella zoster virus antibody indirect ELISA.
We have developed a cheaper an simple in house indirect ELISA that uses the live attenuated VZV vaccine as a coating antigen. The alternative ELISA had an agreement of 94% when compared with a commercial VZV ELISA kit. Moreover, our ELISA proved to be more reliable than the kit when assessing true negative samples. By adding a standard serum, we were able to produce results in international units per millilitre. Also, the addition of an extra step with 8M urea allowed the assessment of VZV IgG avidity without excessive costs. The cost per sample to test VZV IgG was 2.7 times cheaper with our ELISA, allowing the testing of many samples without the burden of production of VZV antigen in the laboratory. 2466 related Products with: A simple and cheaper in house varicella zoster virus antibody indirect ELISA.
