Scientific Data Images for Human IGF-I/IGF-1 Antibody
IGF-I/IGF-1 in MDA-MB-231 and PC-3 Human Cell Lines.
IGF-I/IGF-1 was detected in immersion fixed MDA-MB-123 human breast cancer cell line (left panel, positive stain) and PC-3 human prostate cancer cell line (right panel, negative stain) using Rat Anti-Human IGF-I/IGF-1 Monoclonal Antibody (Catalog # MAB2913) at 8 µg/mL for 3 hours at room temperature. Cells were stained using the NorthernLights™ 557-conjugated Anti-Rat IgG Secondary Antibody (red; Catalog # NL013) and counterstained with DAPI (blue). Specific staining was localized to cytoplasm.

Background: IGF-I/IGF-1
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).
