| 蛋白性状 | Lyophilized powder |
| 缓冲液 | Lyophilized from 0.22 μm filtered solution in 20 mM Tris, 300mM NaCl (pH 8.5). Normally 8% trehalose is added as protectant before lyophilization. |
| 存储 | 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. |
| 运输方式 | In general, Lyophilized powders are shipping with blue ice. Solutions are shipping with dry ice. |
| 研究背景 | Two of the four human FGF8 splice isoforms, FGF8a and FGF8b, are expressed in the mid-hindbrain region during development. Although the only difference between these isoforms is the presence of an additional 11 amino acids at the N terminus of FGF8b, these isoforms possess remarkably different abilities to pattern the midbrain and anterior hindbrain. |
