Used in immunological research to quantify mouse β-defensin levels in biological samples such as serum, plasma, tissue homogenates, and cell culture supernatants. Helps study innate immunity, particularly in mucosal surfaces and skin, where β-defensins play a role in antimicrobial defense and immune modulation. Commonly applied in research on inflammation, infection models, and autoimmune diseases to assess host defense peptide responses. The kit enables sensitive and specific detection, supporting studies on the regulation of defensin expression and their role in disease progression or therapeutic interventions.
