Immunogen	Native defensins. The epitope has not been further characterized.
Specificity	Several Defensins are recognized. This antibody recognises a family of Cyclic Peptides in Neutrophils. Human: Defensin 1-3 (HNP-1 to HNP-3) in Human Neutrophils. Synthetic Defensin-1 and -2 (Bachem, Bubendorf CH) stain also positively. Not tested with Defensin-4. A side reaction to elastin has been observed in humans. Other: not tested. Defensins have been described in rabbits (NP-1 to NP-5, NP3a = Corticostatin), and in mice (cryptodin).

Background	Defensins are a family of cyclic peptides containing 29-35 amino acids (MW < 3500) which tend to form aggregates. Four of these peptides are described in humans (HNP-1 to 4), six in rabbits (NP-1 to 5). Synonyms are MCP-1 for NP-1, MCP-2 for NP-2 and corticostatin for NP-3. Biological Functions: Various functions have been described for defensins. They are antibacterial, antifungal, chemotactic for monocytes, inhibitory for ACTH-induced corticosteroid synthesis and cytotoxic for cells. Defensins are inhibited by glucosaminoglycans (self protection for cells) and high concentrations of Ca2+ ions.
