We developed and validated a high-throughput human papillomavirus (HPV) The Pseudovirion-Luminex method gave similar results as ELISA (Kappa= 0.77).
ELISA (enzyme-linked immunosorbent assay) is a powerful method for detecting and quantifying specific proteins. ELISA typically requires that the antigen of interest be captured or immobilized on a solid surface and then be complexed with an antibody that is linked to an enzyme.

ELISA typically requires that the antigen of interest be captured or immobilized on a solid surface and then be complexed with an antibody that is linked to an enzyme. Although there are a number of documents published on method validation (1, 2) which target analytical methods in general, and there are numerous publications on validation of ELISA methods for pesticides, these documents do not address specifi c areas of concern for food allergen analysis, such as reference materials, spiking methods, or choice of matrixes. KEYWORDS: Competitive ELISA - Data expression - Indirect ELISA - Quality control - Reference standards - Standardisation - Validation. INTRODUCTION The definitive diagnosis of infectious disease has traditionally been accomplished through the direct demonstration and identification of the causative agent(s) by culture and isolation procedures.
