Alpha-DEFENSIN (1-3), HNP1-3

Catalogue number: HNP103

Units100 µg
Application Flow Cytometry
Immunohistochemistry (frozen)
Immunohistochemistry (paraffin)

The monoclonal antibody DEF-3 reacts with human alpha-defensins (HNP1-3), which are synthesized and stored by neutrophilic granulocytes. Human defensins are Cys-rich antimicrobial peptides which specifically react against Gram-negative bacteria. Originally defensins were isolated from hemolysates, but they can also be found on the cell surface of epithelia of the urogenital tract, lung, and trachea. In leukocytes defensins are stored in granules being released into phagolysosomes for the destruction of incorporated microorganisms. Amino acid sequences of alpha-defensins 1-4 (HNP1-4) and beta-Defensins 1-4 (HBD1-4) are known. Human Neutrophil Peptides (HNP1-3) syn. alpha-Defensins 1-3, reactivity with HNP-4 not tested.
