Reconstitute with 0.1 mL of distilled water. For long term storage the addition of 0.09% sodium azide is recommended (unless the product will be used for functional studies). Prior to reconstitution, store at 4°C. After reconstitution, store undiluted at -20°C, avoiding freeze/thaw cycles. This antibody may be used in indirect ELISA or as a capture reagent in sandwich ELISA with PA1-86912 as a detection reagent. Rabbit anti Human insulin-likegGrowth factor I antibody recognizes human IGF-I (Insulin-like Growth Factor I), a 70 amino acid secreted mitogenic polypeptide and member of the insulin gene family, produced primarily by the liver.

IGF1 (Insulin-like growth factor-1) 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. Further, IGF1 is a polypeptide growth factor that stimulates the proliferation of a wide range of cell types in muscle, bone, and cartilage tissue. 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 circulation, IGFs are predomitly bound to binding proteins (IGFBPs) which prolong the half-life of the IGFs and play a role in delivering them to target tissues. IGF-I is known as one of the most potent activators of the AKT signaling pathway which is known to be a stimulator of proliferation and an inhibitor of programmed cell death. Moreover, mature human IGF-I is 100% homologous with bovine and porcine proteins. Low levels of IGF1 have been linked to Alzheimer ft.s disease. IGF1 is processed from a precursor, bound by a specific receptor, and secreted. Defects in the IGF1 gene are a cause of insulin-like growth factor 1 deficiency and several transcript variants encoding different isoforms have been found.
