The present disclosure generally relates to nanoparticles adsorbed with gliadin molecules. In addition, the present disclosure relates to methods of preparing the nanoparticles adsorbed with gliadin molecules and methods of using said nanoparticles including detecting anti-gliadin 5 antibodies in a sample, diagnosing gluten-related disorders, and other applications.

Nanoparticles adsorbed with gliadin molecules

The present invention provides the recombinant cloning and sequencing of two of the majorgametocyte antigens having molecular weights of 56 and 82 kDa and the expression of these recombinant antigens in anexpression system using the plasmid pTrcHis. The subject invention also provides a vaccine against coccidiosis comprising the recombinant 56 kDa or 82 kDa antigen. The subject invention also provides two 30 kDa proteins and three 14 kDa proteins fromgametocytes having at the N-terminal end the amino acid sequence described herein. The subject invention also provides a vaccine against coccidiosis comprising the recombinant 56 kDa or 82 kDa antigen and any of the aforementioned proteins. Additionally, the subject invention also provides a method of immunizing a subject against infection byor, or a microorganism expressing an immunologically cross-reactive antigen, comprising the step of administering to the subject any of the aforementioned vaccines.
