Western blot analysis of human IGF1 was performed by loading the indicated amounts of recombinant human IGF1 protein per well onto a 4-20% Tris-HCl polyacrylamide gel. Proteins were transferred to a PVDF membrane and blocked with StartingBlock (TBS) Blocking Buffer (Product # 37542) for at least 1 hour. The membrane was probed with an IGF1 polyclonal antibody (Product # PA1-130) at a concentration of 1ug/ml overnight at 4C on a rocking platform, washed in TBS-0.1%Tween-20, and probed with a goat anti-rabbit IgG-HRP secondary antibody (Product # 31460) at a dilution of 1:10000 for at least 1 hour. Chemiluminescent detection was performed using SuperSignal West Pico (Product # 34080).

Insulin-like growth factor-1 (IGF1), is structurally and functionally related to insulin but has a much higher growth-promoting activity. A variety of cellular responses are induced by IGF1, including cell proliferation, differentiation, migration, and survival. IGF1 stimulates glucose transport in rat bone-derived osteoblastic (PyMS) cells and is effective at much lower concentrations than insulin, not only regarding glycogen and DNA synthesis but also with regards to enhancing glucose uptake. In the circulation, the IGFs are predominantly bound to binding proteins (IGFBPs) which prolong the half-life of the IGFs and play a role in delivering them to target tissues. Low levels of IGF1 have been linked to Alzheimer's disease.
