protein/Z02754-beta-Defensin_1_BD-1_Human, Defensins (alpha and beta) are cationic peptides with a broad spectrum of antimicrobial activity that comprise an important arm of the innate immune system. The ª-defensins are distinguished from the ß-defensins by the pairing of their three disulfide bonds. To date, four human ß-defensins have been identified, BD-1, BD-2, BD-3 and BD-4. ß-defensins are expressed on some leukocytes and at epithelial surfaces. In addition to their direct antimicrobial activities, they are chemoattractant towards immature dendritic cells and memory T cells. The ß-defensin proteins are expressed as the C-terminal portion of precursors and are released by proteolytic cleavage of a signal sequence and, in the case of BD-1 (36 a.a.), a propeptide region. ß-defensins contain a six-cysteine motif that forms three intra-molecular disulfide bonds. ß-Defensins are 3-5 kDa peptides ranging in size from 33-47 amino acid residues.</td></tr><tr><th>M.W.</th><td colspan="7"> Approximately 5.0 KDa, a single non-glycosylated polypeptide chain containing 47 amino acids.</td></tr><tr><th>Purity</th><td colspan="7"> >98% by SDS-PAGE and HPLC analyses.</td></tr><tr><th>Endotoxin Level</th><td colspan="7"> Less than 0.2EU/ug of rHuBD-1 as determined by LAL method.</td></tr><tr><th>Specific Activity</th><td colspan="7"> Fully biologically active when compared to standard.

Reconstitution |
We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Reconstitute in sterile distilled water or aqueous buffer containing 0.1% BSA to a concentration of 0.1-1.0 mg/mL. Stock solutions should be apportioned into working aliquots and stored at < -20 °, C. Further dilutions should be made in appropriate buffered solutions. |
Formulation |
Lyophilized from a 0.2µ, m filtered concentrated, solution in 20mM PB, pH 7.4, 130mM NaCl. |
Endotoxin Level |
Less than 0.2EU/ug of rHuBD-1 as determined by LAL method. |
