Used in immunological research to detect and quantify ovalbumin-specific IgG antibodies in biological samples. Commonly applied in studies involving immune response to allergens, particularly in models of food allergy or asthma where ovalbumin is used as a model antigen. Enables researchers to assess the strength and specificity of humoral immune responses following sensitization or immunotherapy. Widely utilized in preclinical studies, vaccine development, and allergy research to measure antigen-specific antibody levels in serum, plasma, or cell culture supernatants. Provides a reliable, high-throughput method for evaluating immune modulation in experimental animals or in vitro systems.
