Used in immunological research to quantify mouse β-defensin 2 levels in biological samples such as serum, plasma, tissue homogenates, and cell culture supernatants. This ELISA kit enables researchers to study the role of β-defensin 2 in innate immunity, particularly in host defense against microbial pathogens, inflammation, and immune regulation. It is commonly applied in studies related to infectious diseases, mucosal immunity, and autoimmune conditions in mouse models. The assay provides a sensitive and specific means to monitor changes in β-defensin 2 expression under experimental treatments or disease states, supporting investigation into antimicrobial peptide dynamics and immune response modulation.
