Recombinant Mouse IGF-I (Catalog #
791-MG) stimulates cell proliferation in a serum-free assay using the MCF-7 human breast cancer cell line. The ED50 for this effect is 0.4-2 ng/mL.
1 µg/lane of Recombinant Mouse IGF-I was resolved with SDS-PAGE under reducing (R) conditions and visualized by silver staining, showing a single band at 8 kDa.
Background: IGF-I

Insulin-like growth factor I, also known as somatomedin C, is the dominant effector of growth hormone and is structurally homologous to proinsulin. Mouse IGF-I is synthesized as two precursor isoforms with alternate N- and C-terminal propeptides (1). These isoforms are differentially expressed by various tissues (1). The 7.6 kDa mature IGF-I is identical between isoforms and is generated by proteolytic removal of the N- and C-terminal regions. Mature mouse IGF-I shares 94% and 99% aa sequence identity with human and rat IGF-I, respectively (2), and exhibits cross-species activity. It shares 60% aa sequence identity with mature mouse
IGF-II. Circulating IGF-I is produced by hepatocytes, while local IGF-I is produced by many other tissues in which it has paracrine effects (1). IGF-I induces the proliferation, migration, and differentiation of a wide variety of cell types during development and postnatally (3). IGF-I regulates glucose and fatty acid metabolism, steroid hormone activity, and cartilage and bone metabolism (4 - 7). It plays an important role in muscle regeneration and tumor progression (1, 8). IGF-I binds
IGF-I R, IGF-II R, and the insulin receptor, although its effects are mediated primarily by IGF-I R (9). IGF-I association with IGF binding proteins increases its plasma half-life and modulates its interactions with receptors (10).
