Sandwich ELISAs have been produced to detect ruminant and porcine heat stable proteins which have been heated to 130°C, 2.7 bar (absolute pressure), for 30 mins and incorporated into compound animal feedstuffs (CAFs). Sample preparation involves heat treatment, removal of CAF proteins and analyte concentration. The test system incorporates a separate ELISA to detect non-specific binding of certain plant derived CAF components, each of which are identified. Both ruminant and porcine heat stable antigens are detected at a concentration of 1250 ppm. %CVs obtained within assay were 6.97% and between assay 9.07%. The maximum calculated false negative rate over 3 years of routine operation of the ELISAs was <1%. Each assay plate incorporates 12 negative controls permitting an additional 3SD calculation to overcome any in-plate variation.
