Catalog# C126 Source E.coli Description Recombinant Human β-Defensin 4/DEFB4 is produced with our E. coli expression system. The target protein is expressed with sequence (Glu23-Pro72) of Human β-Defensin 4. Names Beta-Defensin 104, Beta-Defensin 4, BD-4, DEFB-4, hBD-4, Defensin Beta 104, DEFB104A, DEFB104, DEFB4, DEFB104B Accession # Q8WTQ1 Formulation Lyophilized from a 0.2 μm filtered solution of 20mM PB, 130mM NaCl, pH 7.4 Shipping The product is shipped at ambient temperature. Reconstitution Always centrifuge tubes before opening. Do not mix by vortex or pipetting.
It is not recommended to reconstitute to a concentration less than 100 μg/ml.
Dissolve the lyophilized protein in 1X PBS.
Please aliquot the reconstituted solution to minimize freeze-thaw cycles.Storage 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.Purity Greater than 95% as determined by SEC-HPLC and reducing SDS-PAGE. Endotoxin Less than 0.1 ng/μg (1 IEU/μg). Amino Acid Sequence EFELDRICGYGTARCRKKCRSQEYRIGRCPNTYACCLRKWDESLLNRTKPBackground Defensins are cationic peptides. It is an important ingredient of the innate immune system. β-defensins are expressed on some leukocytes and epithelial surfaces. Four human β-Defensins have been identified to date: BD-1, BD-2, BD-3 and BD-4. β-defensins contain a six-cysteine motif, they forms three intra-molecular disulfide bonds. β-defensins are also chemoattractant towards immature dendritic cells and memory T cells. The β-defensin proteins are expressed as the C-terminal portion of precursors; they are released by proteolytic cleavage of a signal sequence.
