Human DEFA4 (Neutrophil defensin 4) ELISA KIT (HUFI05313)

A quantitative immunoassay from Assay Genie that measures human alpha-defensin 4 (DEFA4), an antimicrobial peptide secreted by neutrophils during innate immune responses. The kit supports research into sepsis biomarkers, mucosal immunity, inflammatory disorders, and host-pathogen defense mechanisms. Using a colorimetric readout, the assay quantifies DEFA4 levels in blood-derived research samples, with reactivity confirmed against the human protein. Each kit provides reagents sufficient for 96 individual determinations in a standard microplate format. Reagents should be stored refrigerated and protected from light per the enclosed product insert. Used across academic laboratories, translational research programs, and pharmaceutical discovery workflows investigating antimicrobial peptide expression and neutrophil biology. Intended for research use only.
