ELISA Capture (Matched Antibody Pair)
2-8 µg/mL 

Use in combination with:

Detection Reagent: Mouse IGF-I/IGF-1 Biotinylated Antibody (Catalog # BAF791)

Standard: Recombinant Mouse IGF-I/IGF-1 Protein, CF (Catalog # 791-MG)

Neutralization
Measured by its ability to neutralize IGF‑I-induced proliferation in the MCF‑7 human breast cancer cell line. Karey, K.P. et al. (1988) Cancer Research 48:4083. The Neutralization Dose (ND50) is typically 0.3-1.5 µg/mL in the presence of 15 ng/mL Recombinant Mouse IGF‑I.

Please Note: Optimal dilutions should be determined by each laboratory for each application. General Protocols are available in the Technical Information section on our website.

Cell Proliferation Induced by IGF-I/IGF-1 and Neutralization by Mouse IGF-I/IGF-1 Antibody. Recombinant Mouse IGF-I/IGF-1 (Catalog # 791-MG) stimulates proliferation in the MCF-7 human breast cancer cell line in a dose-dependent manner (orange line). Proliferation elicited by Recombinant Mouse IGF-I/IGF-1 (15 ng/mL) is neutralized (green line) by increasing concentrations of Mouse IGF-I/IGF-1 Monoclonal Antibody (Catalog # MAB791). The ND50is typically 0.3-1.5 µg/mL.

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. Mouse IGF-I/IGF-1 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/IGF-1 is identical between isoforms and is generated by proteolytic removal of the N- and C-terminal regions. Mature mouse IGF-I/IGF-1 shares 94% and 99% amino acid (aa) sequence identity with human and rat IGF-I/IGF-1, respectively (2), and exhibits cross-species activity. It shares 60% aa sequence identity with mature mouse 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/IGF-1 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).
