Used to quantitatively measure human β-defensin 2 levels in biological samples such as serum, plasma, saliva, and cell culture supernatants. It is widely applied in immunology and inflammation research to study innate immune responses, particularly in epithelial tissues. The kit helps assess β-defensin 2 expression in conditions like psoriasis, atopic dermatitis, respiratory infections, and inflammatory bowel disease. It is also used in studies evaluating antimicrobial peptide production and host defense mechanisms. Due to its role in immune regulation, the assay supports research into autoimmune diseases, infection responses, and potential biomarker development.
