BD 2 Human

Beta Defensin-2 Human Recombinant

Beta Defensin-2 Human Recombinant produced in E.Coli is a single, non-glycosylated polypeptide chain containing 41 amino acids and having a molecular mass of 4.3 kDa.
The BD-2 is purified by proprietary chromatographic techniques.

Accession

O15263

Amino acid sequence

GIGDPVTCLK SGAICHPVFC PRRYKQIGTC GLPGTKCCKK P.

Biological Activity

Determined by the ability to chemoattract human dendritic immature cells at a concentration of 10,000-100,000ng/ml corresponding to a specific activity of 10-100IU/mg.

Formulation

The Human BD-2 was lyophilized from a concentrated (1mg/ml) solution containing 20mM PBS pH-7.4 and 130mM sodium chloride.

Physical Appearance

Sterile Filtered White lyophilized (freeze-dried) powder.

Purity

Greater than 98.0% as determined by:
(a) Analysis by RP-HPLC.
(b) Analysis by SDS-PAGE.

Solubility

It is recommended to reconstitute the lyophilized Beta Defensin-2 in sterile 18MΩ-cm H2O not less than 100ug/ml, which can then be further diluted to other aqueous solutions.

Source

Escherichia Coli.

Stability

Lyophilized Beta Defensin-2 Recombinant although stable at room temperature for 3 weeks, should be stored desiccated below -18oC. Upon reconstitution BD-2 should be stored at 4oC between 2-7 days and for future use below -18oC.
Please prevent freeze-thaw cycles.
