Description | Apolipoprotein E (apoE) is a lipid carrier in both the peripheral and the central nervous systems. Lipid-loaded apoE lipoprotein particles bind to several cell surface receptors to support membrane homeostasis and injury repair in the brain. Considering prevalence and relative risk magnitude, the ε4 allele of the APOE gene is the strongest genetic risk factor for late-onset Alzheimer's disease (AD). Apolipoprotein E/APOE Protein, Mouse, Recombinant (hFc) is expressed in HEK293 mammalian cells with C-hFc tag. The predicted molecular weight is 60.7 kDa and the accession number is P08226. |
Species | Mouse |
Expression System | HEK293 Cells |
Tag | C-hFc |
Accession Number | P08226 |
Synonyms | apolipo E,Apo-E,Apolipoprotein E,APOE |
Construction | Glu19-Gln311 |
Protein Purity | > 95% as determined by Tris-Bis PAGE; > 95% as determined by HPLC |
Molecular Weight | 60.7 kDa (predicted). Due to glycosylation, the protein migrates to 62-66 kDa based on Tris-Bis PAGE result. |
Endotoxin | < 1 EU/μg by the LAL method. |
Formulation | Lyophilized from a solution filtered through a 0.22 μm filter, containing 20 mM PB, 150 mM NaCl (pH 7.4). Typically, 8% trehalose is incorporated as a protective agent before lyophilization. |
Reconstitution | Reconstitute the lyophilized protein in distilled water. The product concentration should not be less than 100 μg/ml. Before opening, centrifuge the tube to collect powder at the bottom. After adding the reconstitution buffer, avoid vortexing or pipetting for mixing. |
Stability & Storage | It 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. |
Shipping | In general, Lyophilized powders are shipping with blue ice. |
