|---|---|
| SOURCE SPECIES: | E. coli |
| SEQUENCE: | EFELDRICGY GTARCRKKCR SQEYRIGRCP NTYACCLRKW DESLLNRTKP |
| TESTED APPLICATIONS: | |
| BIOLOGICAL ACTIVITY: | Determined by its ability to chemoattract human monocytes using a concentration range of 0.1 - 100.0 ng/mL. |
Properties
| PURITY: | Greater than 98% by SDS-PAGE gel and HPLC analyses. Endotoxin level is less than 0.1 ng per μg (1EU/μg). |
|---|---|
| PHYSICAL STATE: | Lyophilized |
| STORAGE CONDITIONS: | The lyophilized BD-4 recombinant protein is stable for at least 2 years from date of receipt at -20˚C. Reconstituted BD-4 is stable for at least 3 months when stored in working aliquots with a carrier protein at -20˚C. As with any protein, exposing BD-4 recombinant protein to repeated freeze / thaw cycles is not recommended. When working with proteins care should be taken to keep recombinant protein at a cool and stable temperature. |

Background
| 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 α-defensins are distinguished from the β-defensins by the pairing of their three disulfide bonds. To date, four human β-defensins have been identified; BD-1, BD-2, BD-3 and BD-4. The β-defensin proteins are expressed as the C-terminal portion of precursors and are released by proteolytic cleavage of a signal sequence. β-defensins contain a six-cysteine motif that forms three intra-molecular disulfide bonds. β-defensins are 3-5 kDa peptides ranging in size from 33-47 amino acid residues. BD-4 is expressed in testis, stomach, uterus, neutrophils, thyroid, lung and kidney. In addition to its direct antimicrobial activities, BD-4 is chemoattractant towards human blood monocytes. Recombinant human BD-4 is a 6.0 kDa protein containing 50 amino acid residues. |
