本实验采用免疫胶体金技术,建立了一种快速检测饲料中T-2毒素的方法。利用柠檬酸三钠还原法制备胶体金溶液,标记抗T-2毒素单克隆抗体并喷于玻璃纤维素膜上,T-2-HS-BSA及羊抗鼠IgG分别结合于硝酸纤维素膜上,依次将样本垫、胶体金结合垫、硝酸纤维素膜和吸水垫组装在PVC板上,并组装在试剂板中。测试结果表明,T-2免疫胶体金试纸条的检出限为100μg/kg,性能稳定、特异性强、准确率高,15 min内即可完成检测。
本實驗採用免疫膠體金技術,建立瞭一種快速檢測飼料中T-2毒素的方法。利用檸檬痠三鈉還原法製備膠體金溶液,標記抗T-2毒素單剋隆抗體併噴于玻璃纖維素膜上,T-2-HS-BSA及羊抗鼠IgG分彆結閤于硝痠纖維素膜上,依次將樣本墊、膠體金結閤墊、硝痠纖維素膜和吸水墊組裝在PVC闆上,併組裝在試劑闆中。測試結果錶明,T-2免疫膠體金試紙條的檢齣限為100μg/kg,性能穩定、特異性彊、準確率高,15 min內即可完成檢測。

A rapid gold immunochromatograhpic assay was developed for detection of T-2 toxin in feed.The experi-ment was based on the sandwich format with sample pad,gold-labeled pad,nitrocellulose membrane and absorbent paper and PVC board.The colloidal gold particles were coated with the monoclonal anti-T-2 antibodies and then prayed to the gold-labeled pad as detector reagent,while T-2 toxin-bovine serum albumin (BSA) conjugate and goat anti-mouse IgG were prayed to two specific zones of anitrocellulose membrane.With this simple,accurate and sensitive method,100 μg/kg of T-2 toxin was detected in less than 15 min.Therefor the assay allowed for the rapid screening for the determination of T-2 toxin in feed.
