Used in immunological research to quantify β-defensin levels in biological samples such as serum, plasma, and tissue homogenates. Helps assess innate immune responses, particularly in studies related to inflammation, infection, and mucosal immunity. Widely applied in preclinical studies involving rodent models to evaluate antimicrobial peptide expression and immune modulation. Supports research in respiratory, gastrointestinal, and reproductive tract diseases where defensins play a protective role. The kit enables high-throughput, sensitive, and specific detection, making it valuable for monitoring disease progression and therapeutic interventions.
