New multiplexed flow cytometric assay to measure anti-peptide antibody: a novel tool for monitoring immune responses to peptides used for immunization.
Peptide-based vaccination has a great potential for the prevention and treatment of various diseases. There is, however, no appropriate monitoring system to measure immune responses to vaccinated peptides, which hampers the development of therapeutically effective vaccine regimens to various diseases. In this study a new multiplexed flow cytometric assay using the Luminex system to monitor humoral immune responses to vaccinated peptides is described. Although the sensitivity is mostly equal to that of the traditional enzyme-linked immunosorbent assay (ELISA), the new assay has several advantages over ELISA in that it minimizes the amount of sera needed, running costs and working periods, and thus will be a novel tool for monitoring immune responses to vaccinated peptides.
