In this study, SARS N and S proteins and their fragments were expressed and purified, and samples from convalescent SARS patients and blood donors were screened with enzyme-linked immunosorbent assays (ELISAs) that were developed with these proteins. IgG and IgM immunoglobulin were detected in the 58 SARS convalescent plasma specimens using an indirect ELISA developed with entire virus antigens. In this study, the indirect ELISAs were developed with different fragments of SARS structure proteins and used to detect antibodies in 58 SARS plasma specimens donated by convalescent patients 3 months after onset of SARS. ./cache/cord-322329-zqjiiy4l.txt ./txt/cord-322329-zqjiiy4l.txt
