Recombinant Human BD-1

Recombinant Human BD-1

• Synonyms: Defensin beta1
• CAS Number: 9000-83-3
• 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 CD34+ dendritic cells is in a concentration range of 100.0-1000.0 ng/ml.
• Molecular Weight: Approximately 5.1 kDa, a single non-glycosylated polypeptide chain containing 47 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.
