Efficiency and precision of electroimmunoassay for canine factor VIII-related antigen.
Factors that improved the efficiency, precision, and sensitivity of the electroimmunoassay for canine factor VIII-related antigen were investigated. These included rapid electrophoresis, increased rocket heights, deletion of the gel-washing step, and doubling of the sample capacity per plate. The modified assay was reliable and accurate, could be completed within 3 hours, and permitted twice as many determinations. Other experimental variables that affected the assay were the type of agarose and sample diluent, storage conditions of samples before assay, source of antibody, and use of 2 mM calcium lactate.
