CAT No.BT-CYT-571

Beta Defensin-2 Human Recombinant, BD 2 Human, 20ug

---

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.

Description
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.

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 18M¦¸-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 -18¡ãC. Upon reconstitution BD-2 should be stored at 4¡ãC between 2-7 days and for future use below -18¡ãC.
Please prevent freeze-thaw cycles.
