Introduction | The Defensin family are highly similar in their protein sequence and are microbicidal & cytotoxic peptides made by neutrophils. Beta Defensin-1 is an antimicrobial peptide having the resistance of epithelial surfaces to microbial colonization. Beta Defensin-1 has close proximity to Defensin Alpha-1 and has been implicated in the pathogenesis of cystic fibrosis. Skin of patients having atopic dermatitis patients and mycosis fungoides (non-lesional and lesional) show lower human Beta Defensin-1 mRNA expression and higher human Beta Defensin-2 and human Beta Defensin-3 mRNA expression. Beta Defensin is highly expressed by epithelial cells. Beta-defensin 1 may play a role in the pathogenesis of severe sepsis. |
Description | BD-1 Rat Recombinant produced in E.coli is a single, non-glycosylated polypeptide chain containing 37 amino acids and having a molecular mass of 4.1kDa. The BD-1 is purified by proprietary chromatographic techniques. |
Source | Escherichia Coli. |
Physical Appearance | Sterile Filtered White lyophilized (freeze-dried) powder. |
Formulation | BD-1 protein was lyophilized from a 0.2µm filtered concentrated solution in PBS, pH 7.4. |
Solubility | It is recommended to reconstitute the lyophilized BD-1 in sterile 18M-cm H2O not less than 100µg/ml, which can then be further diluted to other aqueous solutions. |
Stability | Lyophilized BD-1 although stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution BD-1 should be stored at 4°C between 2-7 days and for future use below -18°C. For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA). Please prevent freeze-thaw cycles. |
Purity | Greater than 95.0% as determined by: (a) Analysis by HPLC. (b) Analysis by SDS-PAGE. |
Amino acid sequence | DQYRCLQNGG FCLRSSCPSH TKLQGTCKPD KPNCCRS. |
Biological Activity | Measured by its ability to chemoattract CD34+ dendritic cells using a concentration range of 0.1-1.0 ug/ml. |
Usage | ProSpec's products are furnished for LABORATORY RESEARCH USE ONLY. The product may not be used as drugs, agricultural or pesticidal products, food additives or household chemicals. |
