Patent ID: 7691384

Claim:
A method to detect a plant allergy in a canid, felid or equid comprising: (a) contacting an allergen from a plant with a putative IgE containing composition from said animal, under conditions suitable for formation of an allergen:IgE complex; (b) contacting the putative allergen:IgE complex with a human FcεR molecule under conditions suitable for formation of an allergen:IgE:FcεR molecule complex, wherein either the allergen or the human FcεR molecule is labeled by conjugation to a detectable marker; (c) washing the allergen:IgE:FcεR mixture to remove non-specifically bound labeled- molecule; and (d) detecting the presence of an allergen:IgE:FcεR complex, if present, by detecting the presence of detectable marker, wherein the presence of an allergen:IgE:FcεR complex indicates the animal is allergic to said plant.
