Catalog #: CYT-599
Description:
Beta Defensin-4 Human Recombinant produced in E.Coli is a single, non-glycosylated polypeptide chain containing 50 amino acids and having a molecular mass of 6 kDa.
The BD-4 is purified by proprietary chromatographic techniques.
Synonyms:
HBD-4, DEFB-4, HBD4, DEFB104B, Beta-defensin 4, BD-4.
Source:
Escherichia Coli.
Amino Acid Sequence:
EFELDRICGY GTARCRKKCR SQEYRIGRCP NTYACCLRKW DESLLNRTKP.
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-4 in sterile 18MΩ–cm H2O not less than 100 µg/ml, which can then be further diluted to other aqueous solutions.
Formulation:
The DEFB4 (1mg/ml) was lyophilized with 20mM sodium Phosphate buffer pH-7.4 and 130mM NaCl.
Stability:
Lyophilized Beta Defensin-4 Recombinant 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.
Please prevent freeze-thaw cycles.
Activity:
Determined by its ability to chemoattract human monocytes using a concentration range of 0.1-50 ng/ml, corresponding to a specific activity of 20,000-10,000,000 units/mg.
Physical Appearance:
Sterile Filtered White lyophilized (freeze-dried) powder.
