Recombinant Rat Beta Defensin -3

Synonyms       Beta-defensin 3, BD-3, Defensin beta 3, Defb3.
Introduction     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.
Description     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.
Source     Escherichia Coli.
Physical Appearance      Sterile Filtered White lyophilized (freeze-dried) powder.
Formulation    BD-3 protein was lyophilized from a 0.2µm filtered concentrated solution in PBS, pH 7.4.
Solubility       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.
Stability     Lyophilized BD-3 although stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution BD-3 should be stored at 4°C between 2-7 days and for future use below -18°C. For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA). Please prevent freeze-thaw cycles.
Purity       Greater than 98.0% as determined by:
(a) Analysis by RP-HPLC.
(b) Analysis by SDS-PAGE.
Biological Activity   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.
Amino acid sequence     KKVYNAVSCM TNGGICWLKC SGTFREIGSC GTRQLKCCKK K.
Usage       CHI's products are furnished for LABORATORY RESEARCH USE ONLY. They may not be used as drugs, agricultural or pesticidal products, food additives or household chemicals.
