Clone: DEF-3.
Background: 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.
Positive Control: Infected skin or oral mucosa.
Immunogen: Native Defensins.
Purification Method: Affinity purified IgG, lyophilized from PBS, BSA, and sodium azide**, reconstitute with 0.5 ml sterile water to get a stock solution of 200 µg/ml.
Concentration: 200 µg/ml IgG after reconstitution with 0,5 ml distilled water.

Caution: These antibodies are intended for in vitro research use only. They must not be used for clinical diagnostics and not for in vivo experiments in humans or animals. ** The preservative sodium azide is known to be poisonous and potentially hazardous to health. It should be handled only by trained staff. Despite of the product's low azide concentration it must be handled with care. Dispose according to regional rules!
