Mouse IGF-I/IGF-1 Antibody Summary

Species Reactivity
Detects mouse IGF-I/IGF-1 in direct ELISAs and Western blots. In direct ELISAs, approximately 15% cross-reactivity with recombinant human IGF-I/IGF-1 is observed, and less than 2% cross-reactivity with recombinant mouse IGF-II/IGF-2 is observed.
Polyclonal Goat IgG
Antigen Affinity-purified
E. coli-derived recombinant mouse IGF-I/IGF-1
Accession # Q8CAR0
Lyophilized from a 0.2 μm filtered solution in PBS with Trehalose. *Small pack size (SP) is supplied either lyophilized or as a 0.2 µm filtered solution in PBS.
Endotoxin Level
<0.10 EU per 1 μg of the antibody by the LAL method.

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 concen-trations of Goat Anti-Mouse IGF-I/IGF-1 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF791). The ND50 is typically 0.2-1.0 µg/mL.

Immunohistochemistry IGF-I/IGF-1 antibody in Mouse Embryo by Immunohistochemistry (IHC-Fr). View Larger

IGF-I/IGF-1 in Mouse Embryo. IGF-I/IGF-1 was detected in immersion fixed frozen sections of mouse embryo (13 d.p.c.) using Goat Anti-Mouse IGF-I/IGF-1 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF791) at 15 µg/mL overnight at 4 °C. Tissue was stained using the Anti-Goat HRP-DAB Cell & Tissue Staining Kit (brown; Catalog # CTS008) and counterstained with hematoxylin (blue). Lower panel shows a lack of labeling when primary antibodies are omitted and tissue is stained only with secondary antibody followed by incubation with detection reagents. Specific staining was localized to developing brain and muscle cells. View our protocol for Chromogenic IHC Staining of Frozen Tissue Sections.

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 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).
