Expression System
HEK293 Cells
TagC-hFc
Accession NumberP09923
ConstructionA DNA sequence encoding the mature form of human ALPI (P09923) (Met 1-Asp 503),without the pro peptide, was expressed with the fused Fc region of human IgG1 at the C-terminus. Predicted N terminal: Val 20
Protein Purity
> 83 % as determined by SDS-PAGE
Endotoxin< 1.0 EU/μg of the protein as determined by the LAL method.
FormulationLyophilized from a solution filtered through a 0.22 μm filter, containing PBS, pH 7.4. Typically, a mixture containing 5% to 8% trehalose, mannitol, and 0.01% Tween 80 is incorporated as a protective agent before lyophilization.
ReconstitutionA Certificate of Analysis (CoA) containing reconstitution instructions is included with the products. Please refer to the CoA for detailed information.
SynonymsIAP, alkaline phosphatase, intestinal
Research Background
ALPI encodes for intestinal phosphatase alkaline, a brush border metalloenzyme that hydrolyses phosphate from the lipid A moiety of lipopolysaccharides and thereby drastically reduces Toll-like receptor 4 agonist activity. ALPI mutations impaired either stability or catalytic activity of ALPI and rendered it unable to detoxify lipopolysaccharide-dependent signalling. ALPI mutations should be included in screening for monogenic causes of inflammatory bowel diseases and lay the groundwork for ALPI-based treatments in intestinal inflammatory disorders.
Chemical Properties
Molecular Weight79.5 kDa (predicted); 90-95 kDa (reducing condition, due to glycosylation)
Storage & Solubility Information
ShippingIn general, lyophilized powders are shipped with blue ice, while solutions are shipped with dry ice.
StorageIt is recommended to store recombinant proteins at -20°C to -80°C for future use. Lyophilized powders can be stably stored for over 12 months, while liquid products can be stored for 6-12 months at -80°C. For reconstituted protein solutions, the solution can be stored at -20°C to -80°C for at least 3 months. Please avoid multiple freeze-thaw cycles and store products in aliquots.
