目标/特异性 | Detects human and mouse IGF-I R in direct ELISAs and Western blots. In direct ELISAs and Western blots, 25-50% cross-reactivity with recombinant mouse IGF-I R is observed. In direct ELISAs, less than 1% cross-reactivity with recombinant human IGF‑II R is observed. |
使用方法 | Western Blot: 0.1 µg/mL Immunohistochemistry: 5-15 µg/mL 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 0.5-1.5 µg/mL in the presence of 6 ng/mL Recombinant Human IGF‑I. |

背景 | IGF-I receptor is a disulfide-linked heterotetrameric transmembrane protein consisting of two alpha and two beta subunits. Both the alpha and beta subunits are encoded within a single receptor precursor cDNA. The proreceptor polypeptide is proteolytically cleaved and disulfide-linked to yield the mature heterotetrameric receptor. The alpha subunit of IGF-I receptor is extracellular while the beta subunit has an extracellular domain, a transmembrane domain and a cytoplasmic tyrosine kinase domain. The IGF-I receptor is highly expressed in all cell types and tissues. Essentially all of the biological activities of IGF-I and II have been shown to be mediated via IGF-I R. |

Cell Proliferation Induced by IGF‑I and Neutralization by Human IGF‑I R Antibody. Recombinant Human IGF‑I (Catalog # 291-G1) stimulates proliferation in the MCF‑7 human breast cancer cell line in a dose-dependent manner (orange line). Proliferation elicited by Recombinant Human IGF‑I (6 ng/mL) is neutralized (green line) by increasing concentrations of Human IGF-I R Antigen Affinity-purified Polyclonal Antibody (Catalog # AF-305-NA). The ND50 is typically 0.5-1.5 µg/mL. | |
IGF‑I R in Human Placenta. IGF‑I R was detected in immersion fixed paraffin-embedded sections of human placenta (chorionic villi) using 15 µg/mL Human IGF‑I R Antigen Affinity-purified Polyclonal Antibody (Catalog # AF‑305‑NA) overnight at 4 °C. Tissue was stained with the Anti-Goat HRP-DAB Cell & Tissue Staining Kit (brown; Catalog # CTS008) and counterstained with hematoxylin (blue).

IGF-I R in Mouse Embryo. IGF-I R was detected in immersion fixed frozen sections of mouse embryo using Human IGF-I R Antigen Affinity-purified Polyclonal Antibody (Catalog # AF-305-NA) at 10 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 if primary antibodies are omitted and tissue is stained only with secondary antibody followed by incubation with detection reagents.
