Abstract: The present invention provides transgenic plants cells that express a peptide mimotope of the non-peptide mycotoxin deoxynivalenol. In particular, the peptide mimotope competes with deoxynivalenol for binding to a monoclonal antibody and is antagonistic to the inhibitory effects of deoxynivalenol on in vitro protein synthesis. ransgenic plants expressing the peptide mimotype are resistant to deoxynivalenol.

Abstract: The present invention provides a peptide mimotope of the non-peptide mycotoxin deoxynivalenol. In particular, the peptide mimotope competes with deoxynivalenol for binding to a monoclonal antibody and is antagonistic to the inhibitory effects of deoxynivalenol on in vitro protein synthesis. The present invention also provides a method that uses the peptide mimotope to determine whether corn, grains or mixed feed is contaminated with fungi that produces deoxynivalenol. The present invention further provides transgenic plants resistant to deoxynivalenol.

Abstract: Novel monoclonal antibodies to an aflatoxin B.sub.1 and G.sub.1 in a test kit and used in a method of testing are described. The method for producing the monoclonal antibodies uses repeated administration of aflatoxin B.sub.1 or the related analog compound as a 1-position polypeptide to a murine and production of a hybridoma to generate the novel monoclonal antibodies. The novel antibodies have limited cross-reactivity to aflatoxins B.sub.2, G.sub.2 and M.sub.1. Aflatoxin B.sub.1 or aflatoxin G.sub.1 are detected in foods and the like using the test kit and method.

Abstract: A method for producing monoclonal antibodies to a trichothecene mycotoxin which are used in a test kit and method of testing are described. The method for producing the monoclonal antibodies uses repeated administration, preferably subcutaneously of a trichothecene polypeptide to a murine and production of a hybridoma to generate the monoclonal antibodies. Trichothecenes are detected in foods and the like using the test kit and method.

Abstract: The present invention relates to novel immunogens which can be employed in a method for eliminating the offensive odor associated with the preparation of meats derived from uncastrated male pigs. "Boar taint," as the characteristic odor has been termed, can be eliminated, or at least substantially reduced by the administration of novel immunogen compositions which are chemical conjugates formed of certain C.sub.19 .DELTA..sup.16 -steroids and their mixtures with a carrier protein. The immunogens can be administered in conventional forms including a vaccine.
