Each phase of the assay was tested to optimize and simplify the assay procedure. The accuracy, specificity, reproducibility, and stability of the assay were evaluated. Results indicated that the optimized and modified OPA assay was simple and able to quantify antigen concentration from a standard curve in the 25 µg/mL-600 µg/mL range. The assay accuracy and coefficient of variation (CV) was 95% and less than 8%, respectively, when determining the ricin protein content in the 200 µg/mL vialed RVEc™ FDP. The assay was simple to per
