| Target | Insulin Like Growth Factor 1 (IGF1) |
| Expression | Recombinant |
| Tested Applications | SDS-PAGE |
| Host | E. coli |
| Conjugation | Unconjugated |
| Form | Lyophilized |
| Purity | > 98% (SDS-PAGE and SEC-HPLC) |
| Purification | Purified by proprietary chromatographic techniques. |
| Reconstitution | Reconstitute in sterile 0.4% NaHCO3, pH 8-9, to a concentration of at least 100 µg/ml. This stock solution can be further diluted if required. |
| Storage | Store desiccated at < -18 °C. After reconstitution, store at 4 °C for up to 1 week or aliquot and store at < -18 °C for long term storage. For long term storage, it is recommended to add a carrier protein (0.1% HSA or BSA). Avoid repeated freeze/thaw cycles. |

| Biological Activity | Binding assays of the 125I-Gealthead Seabream IGF1 to Gilthead Seabream or carp (Cyprinus carpio) sera resulted in high specific binding, indicating the existence of one or more IGF-binding proteins. In binding experiments to crude Gilthead Seabream brain homogenate, using human IGF-I as a ligand, the respective IC50 value of hIGF1 was about fourfold lower than that of Gilthead Seabream IGF-1. Recombinant Gilthead Seabream IGF-1 exhibited mitogenic activity in a mouse mammary gland-derived MME-L1 cell line which was approximately 200-fold lower than that of hIGF1. Binding experiments to intact MME-L1 cells suggests that this difference most likely results from a correspondingly lower affinity for IGF1 receptor in these cells. In contrast, the activities of Gilthead Seabream IGF-I and hIGF-I measured by 35S uptake by gill arches from goldfish (Carassius auratus) were identical, indicating that the recombinant Gilthead Seabream IGF-I is biologically active. |
