| Expression System | HEK293 Cells |
| Tag | Tag Free |
| Construction | A DNA sequence encoding the Influenza A virus (A/Anhui/1/2013(H7N9)) Neuraminidase (translated amino acids of EPI439509) (His36-Leu465) was expressed , the cell lysates are collected, and bio-activity was tested. |
| Endotoxin | Please contact us for more information. |
| Formulation | Lyophilized from a solution filtered through a 0.22 μm filter, containing PBS, 0.6%Triton-100, 6% trehalose 5. 3% mannitol 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. |
| Reconstitution | A Certificate of Analysis (CoA) containing reconstitution instructions is included with the products. Please refer to the CoA for detailed information. |
| 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 shipped with blue ice, while solutions are shipped with dry ice. |
