This detailed volume provides a comprehensive collection of methods and protocols in food allergy and food allergens studies. The selected protocols explore the study of food allergens, from recombinant production, purification procedures, IgE and T cell epitopes characterization, to allergen structure description, cellular responses, and tolerance induction, through a variety of techniques and animal models. Written for the highly successful Methods in Molecular Biology series, chapters include introductions to their respective topics, lists of the necessary materials and reagents, step-by-step and readily reproducible laboratory protocols, as well as tips on troubleshooting and avoiding known pitfalls.
