| Expression System | HEK293 Cells |
| Tag | C-6xHis |
| Accession Number | P05112 |
| Amino Acid | His25-Ser153 |
| Construction | His25-Ser153 |
| Protein Purity | Greater than 95% as determined by reducing SDS-PAGE. Greater than 95% as determined by SEC-HPLC.   |
| Endotoxin | < 0.1 ng/µg (1 EU/µg) as determined by LAL test. |
| Formulation | Lyophilized from a solution filtered through a 0.22 μm filter, containing PBS, pH 7.4. |
| 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 | 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 shipped with blue ice, while solutions are shipped with dry ice. |
