Polyclonal Rabbit Affinity Purified E B
Antimicrobial peptides are a common mechanism of host defense utilized by a variety of species, from insects to humans. Defensins are a large family of broad-spectrum antimicrobial peptides, identified originally in leukocytes of rabbits and humans. Defensins, cationic/polar peptides (30-35 aa; 3-4kD), are distinguished by a conserved tri-disulfides and a largely b-Sheet structure. Defensins, expressed at the cell surface, have been hypothesized to function as a biochemical barrier against microbial infection by inhibiting colonization of the epithelium by wide range of pathogenic microorganisms. In leukocytes, these peptides are stored in cytoplasmic granules and are released into phagolysosomes where they contribute to the killing of engulfed microorganisms.
Catalog #B0901-13
The genes encoding human a and ß -defensins are clustered in a contiguous segment of chromosome 8p23. Defensins are classified into two families designated a - and ß - based on distinctive, although similar, tri-disulfide linkages in the peptides. b-defensins are slightly larger and differ in the position and arrangement of 3 disulfides. In humans, six a -defensin (cryptidins), HD 1-6 (HD1-4 are also known as HNP1-4 for Human Neutrophil Peptides), and two ß -defensins, HBD-1 and HBD-2, have been identified to date. Rat (RBD-1 and RBD-2) and mouse (MBD1-4) homologues of the human beta-defensin have also been identified.
ApplicationsSuitable for use in ELISA and Western Blot. Other applications not tested.
Recommended DilutionsWestern Blot: 1-10ug/ml using ECL.
ELISA: 0.5-1ug/ml. Control peptide (B0901-05) can be used to coat ELISA plates at 1ug/ml.
Optimal dilutions to be determined by the researcher.
