DEFB4 Protein, Human, Recombinant

Catalog No. TMPJ-01243
Synonyms: DEFB4, DEFB104B, hBD-4, DEFB104, BD-4, DEFB-4, Beta-Defensin 104, Beta-Defensin 4, β-Defensin 104, Defensin Beta 104, β-Defensin 4, Defensin β104, DEFB104A

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.

Amino Acid Glu23-Pro72
Construction Glu23-Pro72
Protein Purity Greater than 95% as determined by reducing SDS-PAGE. (QC verified)
Molecular Weight 9 KDa (reducing condition)
Endotoxin < 0.1 ng/µg (1 EU/µg) as determined by LAL test.
Formulation Lyophilized from a solution filtered through a 0.22 μm filter, containing 20 mM PB, 130 mM NaCl, pH 7.4.
Reconstitution Reconstitute the lyophilized protein in distilled water. The product concentration should not be less than 100 μg/ml. Before opening, centrifuge the tube to collect powder at the bottom. After adding the reconstitution buffer, avoid vortexing or pipetting for mixing.
Stability & Storage

Lyophilized powders can be stably stored for over 12 months, while liquid products can be stored for 6-12 months at-80℃. For reconstituted proteinsolutions, the solution can be stored at -20°c to -80'c for at least 3 months. Please avoid multiple freeze-thaw cycles and store products in aliquots.
Shipping

In general, Lyophilized powders are shipping with blue ice. Solutions are shipping with dry ice.
