BD-3 Rat Recombinant produced in E.coli is a single, non-glycosylated polypeptide chain containing 41 amino acids and having a molecular mass of 4.5kDa.The BD-3 is purified by proprietary chromatographic techniques.
Defensins form a family of microbicidal and cytotoxic peptides made by neutrophils. Members of the defensin family are highly similar in protein sequence. This gene encodes defensin, beta 103A, which has broad spectrum antimicrobial activity and may play an important role in innate epithelial defense.
It is recommended to reconstitute the lyophilized BD-3 in sterile 18M-cm H2O not less than 100µg/ml, which can then be further diluted to other aqueous solutions. Measured by its antimicrobial activity against E. coli. The ED50 for this effect is typically 4-20µg/ml, corresponding to a specific activity of 50,000-250,000units/mg.
