Abstract
A solid phase Sepharose-based RIA (IgG4 RAST) was compared to the IgG4 FAST enzyme immunoassay for measurements of Ragweed-specific IgG4. Although FAST reagents were used, a standard serum of known antibody content along with modifications in the FAST assay were necessary to attempt to develop a quantitative assay. Various assay parameters such as precision, reproducibility, sensitivity and parallelism were examined. Specificity of the monoclonal anti-IgG4 used in the FAST was not evaluated. Conditions and method of assay for the two systems differed substantially, particularly in the short incubation times for the IgG4 determinations.
