Full biological activity determined by a chemotaxis bioassay using human monocytes is in a concentration range of 0.1-100.0 ng/ml. Appearance
Lyophilized powder. Formulation
Lyophilized after extensive dialysis against 10 mM PB, pH 7.4, 500 mM NaCl. Endotoxin Level
<1 EU/μg, determined by LAL method. Reconstitution
Reconstitute the lyophilized recombinant Rat Beta Defensin-4 (rRtBD-4) to 0.1-1.0 mg/mL using sterile distilled water or aqueous buffer containing 0.1% BSA. Storage & Stability
Lyophilized recombinant Rat Beta Defensin-4 (rRtBD-4) is stored at -20°C. After reconstitution, it is stable at 4°C for 1 week or -20°C for longer. It is recommended to freeze aliquots at -20°C or -80°C for extended storage. Shipping
Room temperature in continental US; may vary elsewhere. Background
Recombinant Rat Beta Defensin-4 is an inducible peptide with a broad spectrum antimicrobial activity. Human Beta Defensin-4 (hBD-4) expression is up-regulated by infection with gram-positive and gram-negative bacteria in human respiratory epithelial cells, and in response to phorbol 12-myristate 13-acetate, but not in response to other inflammatory factors that up-regulate the expression of hBD-2 or hBD-3[1]. |
