Quality control criteria for quantitative enzyme-linked immunosorbent assay of porcine immunoglobulins A and M
1988
Kelley, K.W. | Kleiss, A.J. | Brief, S.
Using radioimmunoassay methods, quality control criteria were applied to monoclonal antibodies produced to measure porcine immunoglobulins by quantitative ELISA. Porcine IgM and IgA were purified to homogeneity and were used to produce murine hybridomas that secreted antibodies against IgM, IgA, and immunoglobulin light chains. A competitive ELISA was developed to measure IgM, and a sandwich ELISA was to quantify IgA in serum and colostrum. Both ELISA were tested for specificity, accuracy, sensitivity, and precision. Monoclonal antibodies were specific for porcine IgM or IgA in serum and colostrum, and competitive and sandwich ELISA fulfilled all validation criteria.
