Used in biomedical research to detect and quantify alpha-defensins (α-DF) in human biological samples such as serum, plasma, and tissue homogenates. Alpha-defensins are antimicrobial peptides released by neutrophils and play a role in innate immunity, inflammation, and host defense. This ELISA kit enables researchers to study the involvement of α-DF in infectious diseases, inflammatory conditions, and immune responses. It is commonly applied in clinical research settings to investigate conditions like sepsis, Crohn’s disease, psoriasis, and respiratory infections where defensin levels are elevated. The assay provides a sensitive and specific means to measure α-DF concentration, supporting studies on disease mechanisms, biomarker discovery, and therapeutic monitoring.
