Neutrophil Defensin 5 (NP5)

Alpha defensins belong together with the beta-defensins to the family of cationic trisulfide-containing microbicidal peptides. They exert their microbicidal activity by permeating the membrane involving the formation of voltage regulated ion channels. Rabbit neutrophils contain large amount of alpha defensins (Neutrophil Defensin) NP 1-6. Defensins constitute more than 15% of total protein in rabbit neutrophils and are accumulated in dense cytoplasmic granules. Rabbit neutrophils express all six rabbit alpha-defensins, NP 1-6. Among myeloid rabbit alpha-defensins NP 1-6, NP 3-6 are neutrophil specific, while NP 1-2 are expressed in rabbit alveolar macrophages. Defensins are relatively resistant to proteolysis, low pH and boiling. Rabbit neutrophil defensins, whose three-dimensional structures are very similar to those of human alpha defensins may be helpful in understanding the role of antimicrobial peptides in innate and acquired immunity and in the studies on the role of neutrophils in pathological situations and in various rabbit models of human diseases. \n\nApplications: \nSuitable for use in ELISA, Western Blot, Flow Cytometry and Immunohistochemistry. Other applications not tested.\n\nRecommended Dilution:\nWestern Blot: 1:10\nFlow Cytometry: 1:10\nImmunohistochemistry (Paraffin, frozen): 1:10\nOptimal dilutions to be determined by the researcher.\n\nStorage and Stability:\nMay be stored at 4 degrees C for short-term only. Aliquot to avoid repeated freezing and thawing. Store at -20 degrees C. Aliquots are stable for 12 months. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap.
