Sequence: | Gly 49-Met 153 |
Accession: | P18254 |
Storage: | Generally, lyophilized proteins are stable for up to 12 months when stored at -20 to -80°C. Reconstituted protein solution can be stored at 4-8°C for 2-7 days. Aliquots of reconstituted samples are stable at < -20°C for 3 months. |
Shipping: | This product is provided as lyophilized powder which is shipped with ice packs. |
Formulation: | Lyophilized from sterile PBS, pH 7.4. Normally 5 % - 8 % trehalose, mannitol and 0.01% Tween80 are added as protectants before lyophilization. Please refer to the specific buffer information in the printed manual. |
Reconstitution: | Please refer to the printed manual for detailed information. |
Background: | Insulin-like growth factor I (IGF-I or IGF-1), also known as somatomedin C, is the dominant effector of growth hormone and is structurally homologous to proinsulin. IGF-I induces the proliferation, migration, and differentiation of a wide variety of cell types during development and postnatally . IGF-I regulates glucose and fatty acid metabolism, steroid hormone activity, and cartilage and bone metabolism . It plays an important role in muscle regeneration and tumor progression . IGF-I/IGF-1 binds IGF-I R, IGF-II R, and the insulin receptor, although its effects are mediated primarily by IGF-I R . The IGF-I protein associates with IGF binding proteins thereby increasing its plasma half‑life and modulating its interactions with receptors. |
