Scientific Data Images for Human/Mouse IGF-I R/IGF1R Antibody

IGF-I R/IGF1R antibody in MCF-7 and HDLM-2 Human Cell Lines by Immunocytochemistry (ICC).

IGF-I R/IGF1R in MCF‑7 and HDLM-2 Human Cell Lines.

IGF-I R/IGF1R was detected in immersion fixed MCF-7 human breast cancer cell line (positive control, left panel) and HDLM-2 human Hodgkin's lymphoma cell line (negative control, right panel) using Goat Anti-Human/Mouse IGF-I R/IGF1R Antigen Affinity-purified Polyclonal Antibody (Catalog # AF-305-NA) at 1.7 µg/mL for 3 hours at room temperature. Cells were stained using the NorthernLights™ 557-conjugated Anti-Goat IgG Secondary Antibody (red; Catalog # NL001) and counterstained with DAPI (blue). Specific staining was localized to plasma membrane. View our protocols for Fluorescent ICC Staining of Cells on Coverslipsand Fluorescent ICC Staining of Non-adherent Cells.
IGF-I R/IGF1R antibody in Mouse Embryo by Immunohistochemistry (IHC-Fr).

IGF-I R/IGF1R in Mouse Embryo.

IGF-I R/IGF1R was detected in immersion fixed frozen sections of mouse embryo using Goat Anti-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.

IGF-I R/IGF1R antibody in Human Placenta by Immunohistochemistry (IHC-P).

IGF-I R/IGF1R in Human Placenta.

IGF-I R/IGF1R was detected in immersion fixed paraffin-embedded sections of human placenta (chorionic villi) using 15 µg/mL Goat Anti-Human IGF-I R/IGF1R 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).

Background: IGF-I R/IGF1R

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.
