Used in immunological research to detect and quantify ovalbumin-specific IgE antibodies in biological samples. Helps assess allergic responses in experimental models, particularly in studies related to food allergy, asthma, and hypersensitivity reactions. Commonly applied in preclinical studies involving rodents to evaluate immune modulation, efficacy of therapeutic interventions, and mechanisms of allergic sensitization. Provides a reliable and sensitive method for measuring IgE levels, supporting research in immunology, allergy, and vaccine development.
