Data is not available. Appearance
Lyophilized powder. Formulation
Lyophilized after extensive dialysis against 20 mM Tris-HCl, 150 mM NaCl, 2 mM CaCl2, pH 7.5. Endotoxin Level
<1 EU/μg, determined by LAL method. Reconstitution
Reconstitute the lyophilized recombinant Human Serpin A1/alpha-1-Antitrypsin, His (HEK293-expressed) (rHuSerpin A1/alpha-1-Antitrypsin, His) to 100 µg/mL using ddH2O or diluted with PBS. Storage & Stability
Lyophilized recombinant Human Serpin A1/alpha-1-Antitrypsin, His (HEK293-expressed) (rHuSerpin A1/alpha-1-Antitrypsin, His) 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
Alpha-1-antitrypsin 1-1 (Serpin A1a; AAT) is the most abundant circulating serine protease inhibitor (serpin) and the prototypic member of the serpin super family. The 52-kD Serpin A1a protein is coded by the gene SERPINA1. Serpin A1a plays an important role in modulating immunity, inflammation, proteostasis, apoptosis, and possibly cellular senescence programs. Systemic deficiency in Serpin A1a due to genetic mutations can result in liver failure and chronic lung disease such as emphysema[1]. |
