Recombinant Human BD-3

• Synonyms:

  Defensin beta3

• Source:

  Escherichia coli.

• Purity:

  > 98 % by SDS-PAGE and HPLC analyses.

• Bioactivity:

  Fully biologically active when compared to standard. The ED50 as determined by anti-microbial activity against E.coli. is less than 30 μg/ml, corresponding to a specific activity of > 33.3 IU/mg.

• Molecular Weight:

  Approximately 5.2 kDa, a single non-glycosylated polypeptide chain containing 45 amino acids.

• Storage Conditions:

  This lyophilized preparation is stable at 2-8 °C, but should be kept at -20 °C for long term storage, preferably desiccated. Upon reconstitution, the preparation is stable for up to one week at 2-8 °C. For maximal stability, apportion the reconstituted preparation into working aliquots and store at -20 °C to -70 °C. Avoid repeated freeze/thaw cycles.

• Formulation:

  Lyophilized from a 0.2 µm filtered concentrated solution in 20 mM PB, pH 7.4, 130 mM NaCl.

• CAS Number:

  9000-83-3
