The consumption of food or feed contaminated with high levels of T-2 toxin may cause adverse health effects in humans and other animals. In this study, to monitor T-2 toxin rapidly in food and feed, a sensitive and specific monoclonal antibody (mAb) against T-2 toxin was generated and a simple and rapid indirect competitive enzyme-linked immunosorbent assay (ic-ELISA) developed. T-2 toxin was first converted to T-2-hemisuccinate (T-2HS) and T-2-hemiglutarate (T-2HG), which were then conjugated to bovine serum albumin (BSA) and ovalbumin (OVA) to prepare an immunogen and coating antigen, respectively. After the inoculation of female Balb/c mice and cell fusions, one cell line, 4D8, with the IgG1 isotype was obtained. The 4D8 antibody exhibited the ability specifically to recognise T-2 toxin with IC50 1.46 µg l(-1). Based on this 4D8 mAb, an optimised ic-ELISA protocol was developed using only methanol-water (7:3, v/v) in feed and cereal samples and ethyl acetate in muscle samples. The limits of detection of T-2 toxin in various sample matrices varied from 0.07 to 15.8 µg kg(-1); the recoveries ranged from 50.3% to 113.6%; and the CVs were less than 19.0%. These results suggest that the prepared mAb and the developed ic-ELISA method will be a useful tool for detecting T-2 toxin in foods and feeds.

UI MeSH Term Description Entries
D004797 Enzyme-Linked Immunosorbent Assay An immunoassay utilizing an antibody labeled with an enzyme marker such as horseradish peroxidase. While either the enzyme or the antibody is bound to an immunosorbent substrate, they both retain their biologic activity; the change in enzyme activity as a result of the enzyme-antibody-antigen reaction is proportional to the concentration of the antigen and can be measured spectrophotometrically or with the naked eye. Many variations of the method have been developed.
