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.
Conseil sur la manipulation
Always centrifuge tubes before opening. Do not mix by vortex or pipetting.
Stock
4 °C/-20 °C/-80 °C
Stockage commentaire
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.
Beta-Defensin 1 (DEFB1) is a member of the beta-defensin family, which is highly expressed by epithelial cells. beta-defensins are expressed as the C-terminal portion of precursors and are released by proteolytic cleavage of a signal peptide. beta-defensins contain a six-cysteine motif that forms three intra-molecular disulfide bonds. beta-defensin 1 is an antimicrobial peptide implicated in the resistance of epithelial surfaces to microbial colonization. Defects in beta-Defensin-1 contribute to asthma diagnosis, with apparent gender-specific effects in human. beta-defensin 1 may also play a role in the pathogenesis of severe sepsis. In addition, beta-defensin 1 is associated with induction profiles in gingival keratinocytes. Alternative Names: Beta-Defensin 1, BD-1, hBD-1, Defensin Beta 1, DEFB1, BD1, HBD1
