Used to measure levels of immunoglobulin E (IgE) in mouse samples such as serum, plasma, or cell culture supernatants. Commonly applied in immunology and allergy research to study allergic responses, asthma models, and immune system activation in mice. Enables quantitative detection of IgE, helping assess the severity of allergic inflammation or the effectiveness of therapeutic interventions in preclinical studies. Widely used in pharmaceutical development and biomedical research involving mouse models of hypersensitivity.
