immunoassays to study prevalence of antibody against gb virus c in blood donors. | immunoassays were developed to determine the seroprevalence of antibody against human gb virus c (gbv-c). the antigenic target in each assay was a 44.6-kda glycosylated protein representing the first 315 amino acids encoded by the gbv-c e2 gene. sera or plasma were assayed for e2 antibody using an anti-human eia format in which antigen-coated polystyrene beads were reacted with sample, and bound antibody was detected by addition of enzyme labelled goat anti-human igg. the presence of anti-e2 ant ... | 1997 | 9395139 |
