Human DEFA3 (Neutrophil defensin 3) ELISA Kit (HUFI05311)

DEFA3 encodes Neutrophil defensin 3 (HNP-3), a 30-amino acid antimicrobial peptide of approximately 3.4 kDa released from azurophilic granules of polymorphonuclear neutrophils during infection and inflammation. Assay Genie's kit supports quantification of circulating peptide levels in blood-derived specimens, with applications spanning sepsis biomarker research, mucosal immunity studies, inflammatory bowel disease investigations, cystic fibrosis airway inflammation work, and periodontitis research. Capture and detection antibodies are specific to the human DEFA3 sequence, and the assay is intended for research use only, helping laboratories profile innate immune activation and antimicrobial peptide responses in clinical cohorts.
