| Construction | 21-147 aa | 
| Protein Purity | > 90% as determined by SDS-PAGE. | 
| Molecular Weight | 43.9 kDa (predicted) | 
| Endotoxin | < 1.0 EU/μg of the protein as determined by the LAL method. | 
| Formulation | If the delivery form is liquid, the default storage buffer is Tris/PBS-based buffer, 5%-50% glycerol. Note: If you have any special requirement for the glycerol content, please remark when you place the order. If the delivery form is lyophilized powder, the buffer before lyophilization is Tris/PBS-based buffer, 6% Trehalose, pH 8.0. | 
| Reconstitution | Reconstitute the lyophilized protein in sterile deionized 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 shipping with blue ice. Solutions are shipping with dry ice. | 
| Research Background | Thyroid hormone-binding protein. Probably transports thyroxine from the bloodstream to the brain. |
