High-Volume Enzyme Immunoassay Test System For Sulfamethazine in Swine

摘要

A high-volume enzyme immunoassay (EIA) system for slaughterhouse screening of sulfamethazine in swine plasma/serum has been developed. The system includes a robotic sample processor that performs most of the liquid handling requirements in the assay. The assay gives good correlation with the widely used thin layer chromatographic method for determination of sulfamethazine in serum and plasma (r = 0.826). Inter- and intra-assay coefficients of variation are less than 10%. Approximately 2,400 serum/plasma samples can be analyzed in a normal working day (8 h) with this system.
