IGF-I, Salmon

Insulin-like growth factor 1 (IGF-1), also called Somatomedin, is a hormone similar in molecular structure to insulin but has a much higher growth-promoting activity. IGF-1 consists of 70 amino acids in a single chain with three intramolecular disulfide bridges. IGF-1 may be a physiological regulator of [1-14C]-2-deoxy-D-glucose (5DG) transport and glycogen synthesis in osteoblasts. It is able to stimulate glucose transport in bone-derived osteoblastic (PyMS) cells and is effective at much lower concentrations than insulin, not only regarding glycogen and DNA synthesis but also with regard to enhancing glucose uptake. It may also play a role in synapse maturation.

Species Salmon
Protein Construction

Expressed with an N-terminal Met.

IGF-1 (Gly45-Ala114)
Accession # Q02815
Purity ≥ 95% as analyzed by SDS-PAGE
Endotoxin Level < 0.2 EU/μg of protein by gel clotting method
Biological Activity ED50 < 15.0 ng/ml as determined by a dose-response proliferation assay using FDC-P1 cells. Based on the ED50, the calculated specific activity is approximately >6.7 × 104 U/mg. It is recommended to experimentally determine the optimal concentration for each specific application by performing a dose response assay.
Expression System E.coli
Theoretical Molecular Weight 7.7 kDa
Apparent Molecular Weight ~8.0 kDa, on SDS-PAGE under reducing conditions.
Formulation Lyophilized after extensive dialysis against PBS.
Reconstitution It is recommended that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Reconstitute the lyophilized powder in H2O up to 100 μg/ml.
Storage & Stability Upon receiving, the lyophilized product remains stable for 6 months at lower than -70℃. Upon reconstitution, the product is stable for 1 week at 4℃ or for 3 months at -20℃. Avoid repeated freeze-thaw cycles by making single-use aliquots before the solution is stored at -20℃.
