Beta Defensin-3 Rat Recombinant ( BD 3 Rat )
DescriptionBD-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.SourceEscherichia
Data sheet
| Formulation | BD-3 protein was lyophilized from a 0.2um 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 100ug/ml, which can then be further diluted to other aqueous solutions. |
| Purity | Greater than 98.0% as determined by:(a) Analysis by RP-HPLC.(b) Analysis by SDS-PAGE. |
| 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. |
| Protein Background | 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. |
| Expression host | Escherichia Coli. |
| Synonyms | Beta-defensin 3, BD-3, Defensin beta 3, Defb3. |
| Reagent Appearance | Sterile Filtered White lyophilized (freeze-dried) powder. |
| 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. |
| Amino acid sequence | KKVYNAVSCM TNGGICWLKC SGTFREIGSC GTRQLKCCKK K. |
| Biological Activity | Measured by its antimicrobial activity against E. coli. The ED50 for this effect is typically 4-20ug/ml, corresponding to a specific activity of 50,000-250,000units/mg. |
