| Construction | A DNA sequence encoding the human IGFBP5 (NP_000590.1 ) (Met1-Glu272) was expressed with a polyhistidine tag at the C-terminus. Predicted N terminal: Leu 21 |
| Protein Purity | > 95 % as determined by SDS-PAGE. ![]() |
| Molecular Weight | 30 kDa (predicted) |
| Endotoxin | < 1.0 EU/μg of the protein as determined by the LAL method. |
| Formulation | Lyophilized from a solution filtered through a 0.22 μm filter, containing 20 mM Tris, pH 8.0, 300 mM NaCl, 10% glycerol. 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 shipping with blue ice. |
