Name Recombinant Human Beta-Defensin 1 (DEFB1) (E. coli)
Description Defensins are a large family of peptides of which two groups exist in mammals: alpha defensins and beta defensins - which are distinguishable by the spacing and connectivity of the conserved cysteine residues within the mature peptides. It is thought that the function of defensins in the eradication of pathogens from the host system is to insert themselves into the bacterial membrane under the influence of membrane potential, in doing so form channels which lead to leakage of cytoplasmic molecules and cell death. Human beta-defensin-1, which has 36 amino acids, was originally isolated from hemofiltrates of patients with advanced renal failure. The BD-1 gene is expressed mainly in the urogenital tract and, to a lesser degree, in trachea and lung, BD-1 is believed to function in the antimicrobial defense of the urogenital and respiratory tracts.

Gene ID 1672
Accession Number P60022
Source E. coli
Species Human (H. sapiens)
Appearance Lyophilized Powder
Molecular Weight 4.2 kDa
Endotoxin Level <1.0 EU/µg of recombinant protein as determined by the LAL method
Purity >95% as determined by SDS-PAGE
Formulation Lyophilized from a 0.2 μm filtered solution in PBS (pH 8)
Function The ED50 was determined by its ability to chemoattract CD34+ dendritic cells using a concentration range of 0.1-1.0 ug/mL.
Reconstitution A quick spin of the vial followed by reconstitution in distilled water to a concentration not less than 0.1 mg/mL. This solution can then be diluted into other buffers.
Storage The lyophilized protein is stable for at least one year from date of receipt at -70°C. Upon reconstitution, this cytokine can be stored in working aliquots at 2° - 8°C for one month, or at -20°C for six months, with a carrier protein without detectable loss of activity. Avoid repeated freeze/thaw cycles.
Usage For research use only. Not for diagnostic or therapeutic use.
