Abstract

Three kinds of immunochromatographic assays (ICAs) are proposedfor the highly sensitive and rapid determination of tylosin (TYL) and tilmicosin (TIM) in eggs based on colloidal gold (CG), latex microsphere (LM), and time-resolved fluorescent microsphere (TRFM). Three types of ICAs could tolerate the egg matrix via simple sample pretreatment and demonstrated high sensitivity for TYL and TIM with cut-off values of 6/6/3μg/kg and 14/14/6μg/kg, respectively. Furthermore, inasingle-blind parallel study 20 egg samples wereanalyzed by the three developed ICAs and confirmed by LC-MS/MS. The results showed good consistency, and there were no false positive and false negative results in our three ICAs. Consequently, the proposed three ICAs offered rapid, highly sensitive, reliable, and selectable testing platforms for screening veterinary medicine or other small molecule contaminants.
