Recombinant Human BD-4

• Synonyms:

  Defensin beta4

• Source:

  Escherichia coli.

• Purity:

  > 98 % by SDS-PAGE and HPLC analyses.

• Bioactivity:

  Fully biologically active when compared to standard. The biological activity determined by a chemotaxis bioassay using human monocytes is in a concentration range of 0.1-100.0 ng/ml.

• Molecular Weight:

  Approximately 6.0 kDa, a single non-glycosylated polypeptide chain containing 50 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
