Background
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. Beta-defensin-1 and beta-defensin-2 share 34% amino acid sequence homology. ß-defensin-2 (HBD-2) whole molecule and N-terminal fragments of HBD-2, no cross-reactivity to alpha-defensin and other beta-defensins, full cross-reaction with mouse and rat beta-defensin-2.

Synonyms: Beta-Defensin-2 (HBD-2/MBD-2)

Source
Rabbits were immunized with a mixture of synthetic peptides (14 AA near N-terminus of the mature HBD-2, 14 AA near N-terminus of the mature rat ß-Defensin-2, and 17 AA near N-terminus of the mature mouse ß-Defensin-2) coupled to KLH.

Product
Rabbit serum lyophilized with PBS and sodium azide 0.05%. Reconstitute with 1 ml bidistilled sterile water.

Specificity

Species Reactivity: Human, mouse, rat, other species not tested

Applications
ELISA, RIA, IHC not established

Working Concentration: (lyophilisate) 1:1000 - 1:5000 WB, 1:10000 - 1:50000 ELISA

Positive Control: Skin or oral mucosa

Storage
The antibody may be stored at +4°C. For prolonged storage prepare appropriate aliquots and store at or below -20°C. Prior to use, an aliquot is thawed slowly in the dark at ambient temperature, spun down again and used to prepare working dilutions by adding sterile phosphate buffered saline (PBS, pH 7.2). Repeated thawing and freezing should be avoided. Working dilutions should be stored at +4°C, not refrozen, and preferably used the same day. If a slight precipitation occurs upon storage, this should be removed by centrifugation. It will not affect the performance or the concentration of the product.

Shipping Conditions: Ship at ambient temperature.
