Technical Data
BD1 (beta Defensin-1)
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-disulfide 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.

Suitable for use in ELISA and Western Blot. Other applications not tested.

Recommended Dilutions:
ELISA: 0.5-1ug/ml, use control peptide to coat plates at 1ug/ml
Western Blot: 1-10ug/ml (ECL.)
Optimal dilutions to be determined by the researcher.
