Used in immunological research to detect and quantify IgE antibodies specific to ovalbumin in biological samples. Commonly applied in allergy studies, particularly in mouse models of food allergy and asthma where ovalbumin is used as an allergen. Enables researchers to assess allergic sensitization, monitor immune responses, and evaluate the efficacy of therapeutic interventions. Suitable for serum, plasma, and cell culture supernatant analysis. Provides a reliable and sensitive method for measuring antigen-specific IgE levels in experimental settings.
