IGF1/IGF-I Protein, Human, Recombinant

IGF I, also known as Mechano Growth Factor, somatomedin-C, IGF-I, and IGF1, is a secreted protein that belongs to the insulin family. The insulin family, comprised of insulin, relaxin, insulin-like growth factors I and II ( IGF-I and IGF-II ), and possibly the beta-subunit of 7S nerve growth factor, represents a group of structurally related polypeptides whose biological functions have diverged. The IGFs, or somatomedins, constitute a class of polypeptides that have a key role in pre-adolescent mammalian growth. IGF-I expression is regulated by GH and mediates postnatal growth, while IGF-II appears to be induced by placental lactogen during prenatal development. IGF1 / IGF-I may be a physiological regulator of [1-14C]-2-deoxy-D-glucose (2DG) transport and glycogen synthesis in osteoblasts. IGF1 / IGF-I 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 about enhancing glucose uptake. Defects in IGF1 / IGF-I are the cause of insulin-like growth factor I deficiency (IGF1 deficiency) which is an autosomal recessive disorder characterized by growth retardation, sensorineural deafness, and mental retardation.

生物活性

1.Measured by its binding ability in a functional ELISA. Immobilized Human IGF1 at 2 μg/ml (100 μl/well) can bind Human IGFBP4 His, the EC50 of Human IGFBP4 His is 10-60 ng/mL. 2. Measured in a serum-free cell proliferation assay using MCF-7 human breast cancer cells. The ED50 for this effect is typically 3.5-14 ng/mL. 3.Human breast cancer organoids were cultured with FGF7, RSPO1, IGF1, EGF, NRG1 Beta 1, NOG. (Routinely tested). 4.Human breast organoids were cultured with IGF1, NRG1 Beta 1. (Routinely tested). 5.Human ovarian organoids were cultured with IGF1, NRG1 Beta 1, RSPO1, EGF, NOG. (Routinely tested).
