  • Restrictions
    For Research Use only
  • Format
    Lyophilized
    Reconstitution
    It is not recommended to reconstitute to a concentration less than 100 μg/mL.
    Dissolve the lyophilized protein in ddH2O.
    Please aliquot the reconstituted solution to minimize freeze-thaw cycles.
    Buffer
    Lyophilized from a 0.2 μm filtered solution of 20 mM PB, 130 mM NaCl, pH 7.4.
    Handling Advice
    Always centrifuge tubes before opening. Do not mix by vortex or pipetting.
    Storage
    4 °C/-20 °C/-80 °C
    Storage Comment
    Lyophilized protein should be stored at < -20°C, though stable at room temperature for 3 weeks.
    Reconstituted protein solution can be stored at 4-7°C for 2-7 days.
    Aliquots of reconstituted samples are stable at < -20°C for 3 months.
    Expiry Date
    3 months

    Background
    Defensins are cationic peptides. It is an important ingredient of the innate immune system. beta-defensins are expressed on some leukocytes and epithelial surfaces. Four human beta-Defensins have been identified to date: BD-1, BD-2, BD-3 and BD-4. beta-defensins contain a six-cysteine motif, they forms three intra-molecular disulfide bonds. beta-defensins are also chemoattractant towards immature dendritic cells and memory T cells. The beta-defensin proteins are expressed as the C-terminal portion of precursors, they are released by proteolytic cleavage of a signal sequence.
