目标/特异性 | Detects human IGF-I R in sandwich ELISAs and Western blots. In sandwich ELISAs, less than 0.15% cross-reactivity or interference was observed with recombinant human (rh) IGF-I, rhIGF-II, rhIL-3 R alpha, rhIL-9 R, and rhTGF-beta RII. |
使用方法 | Western Blot: 1 µg/mL ELISA Capture (Matched Antibody Pair): 2-8 µg/mL ELISA Detection (Matched Antibody Pair): 0.1-0.4 µg/mL ELISA Standard : 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. At 11 µg/mL, this antibody will neutralize approximately 50-75% of the bioactivity due to 6 ng/mL Recombinant Human IGF‑I. |

背景 | Insulin-like growth factor I receptor (IGF-I R) 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 R is extracellular while the beta subunit has an extracellular domain, a transmembrane domain and a cytoplasmic tyrosine kinase domain. IGF-I R 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 Mouse Anti-Human IGF-I R Monoclonal Antibody (Catalog # MAB391). At 11 µg/mL, this antibody will neutralize 50-75% rhIGF-1 induced activity. | |
Detection of Human IGF‑I R by Western Blot. Western blot shows lysates of NTera‑2 human testicular embryonic carcinoma cell line, SK‑Mel‑28 human malignant melanoma cell line, and G361 human melanoma cell line. PVDF membrane was probed with 1 µg/mL of Mouse Anti-Human IGF-I R Monoclonal Antibody (Catalog # MAB391) followed by HRP-conjugated Anti-Mouse IgG Secondary Antibody (Catalog # HAF007). A specific band was detected for IGF-I R at approximately 275 kDa (as indicated). This experiment was conducted under non-reducing conditions and using Immunoblot Buffer Group 2. |
