Scientific Data

Simple Western View Larger

Detection of Human IGF-I/IGF-1 by Simple WesternTM. Simple Western lane view shows lysates of Recombinant Human IGF-1, loaded at 0.2 mg/mL. A specific band was detected for IGF-I/IGF-1 at approximately 6 kDa (as indicated) using 50 µg/mL of Goat Anti-Human IGF-I/IGF-1 Biotinylated Antigen Affinity-purified Polyclonal Antibody (Catalog # BAF291). This experiment was conducted under reducing conditions and using the 2-40kDa separation system.

Background: IGF-I/IGF-1

Insulin-like growth factor I, also known as somatomedin C, is the dominant effector of growth hormone and is structurally homologous to proinsulin. Human IGF-I/IGF-1 is synthesized as two precursor isoforms with N- and alternate C-terminal propeptides (1). These isoforms are differentially expressed by various tissues (1). The 7.6 kDa mature IGF-I/IGF-1 is identical between isoforms and is generated by proteolytic removal of the N- and C-terminal regions. Mature human IGF-I/IGF-1 shares 94% and 96% aa sequence identity with mouse and rat IGF-I/IGF-1, respectively (2), and exhibits cross-species activity. It shares 64% aa sequence identity with mature human IGF-II/IGF-2. Circulating IGF-I/IGF-1 is produced by hepatocytes, while local IGF-I/IGF-1 is produced by many other tissues in which it has paracrine effects (1). IGF-I/IGF-1 induces the proliferation, migration, and differentiation of a wide variety of cell types during development and postnatally (3). IGF-I/IGF-1 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/IGF-1 association with IGF binding proteins increases its plasma half-life and modulates its interactions with receptors (10).
