Scientific Data Images for Human Fibronectin Antibody

Detection of Fibronectin in HepG2 cells by Flow Cytometry

HepG2 (filled histogram) and Jurkat (open histogram) cells were stained with Mouse Anti-Human Fibronectin Monoclonal Antibody (Catalog # MAB1918, filled histogram) followed by Allophycocyanin-conjugated Anti-Mouse IgG Secondary Antibody (Catalog # F0101B). To facilitate intracellular staining, cells were fixed with Flow Cytometry Fixation Buffer (Catalog # FC004) and permeabilized with Flow Cytometry Permeabilization/Wash Buffer I (Catalog # FC005). View our protocol for Staining Intracellular Molecules.

Detection of Human Fibronectin by Western Blot.

Western blot shows lysates of HepG2 human hepatocellular carcinoma cell line and C6 rat glioma cell line. PVDF membrane was probed with 1 µg/mL of Mouse Anti-Human Fibronectin Monoclonal Antibody (Catalog # MAB1918) followed by HRP-conjugated Anti-Mouse IgG Secondary Antibody (HAF018). A specific band was detected for Fibronectin at approximately 300 kDa (as indicated). This experiment was conducted under reducing conditions and using Western Blot Buffer Group 1.

Detection of Human Fibronectin by Simple WesternTM.

Simple Western shows lysates of Exosome Standards (PC‑3) (NBP2-49856), Exosome Standards (Human Urine) (NBP2-49840) and HepG2 human hepatocellular carcinoma cell line, loaded at 0.5 mg/ml. A specific band was detected for Fibronectin at approximately 290 kDa (as indicated) using 10 µg/mL of Mouse Anti-Human Fibronectin Monoclonal Antibody (Catalog # MAB1918). This experiment was conducted under reducing conditions and using the 66-440kDa separation system.
Fibronectin antibody in HepG2 and Daudi Human Cell Lines by Immunocytochemistry (ICC).

Fibronectin in HepG2 and Daudi Human Cell Lines.

Fibronectin was detected in immersion fixed HepG2 human hepatocellular carcinoma cell line (positive staining; left panel) and Daudi human Burkitt's lymphoma cell line (negative staining; right panel) using Mouse Anti-Human Fibronectin Monoclonal Antibody (Catalog # MAB1918) at 3 µg/mL for 3 hours at room temperature. Cells were stained using the NorthernLights™ 557-conjugated Anti-Mouse IgG Secondary Antibody (red; Catalog # NL007) and counterstained with DAPI (blue). Specific staining was localized to cytoplasm.

Fibronectin antibody in Human Breast Cancer Tissue by Immunohistochemistry (IHC-P).

Fibronectin in Human Breast Cancer Tissue.

Fibronectin was detected in immersion fixed paraffin-embedded sections of human breast cancer tissue using Mouse Anti-Human Fibronectin Monoclonal Antibody (Catalog # MAB1918) at 15 µg/mL overnight at 4 °C. Tissue was stained using the Anti-Mouse HRP-DAB Cell & Tissue Staining Kit (brown; Catalog # CTS002) and counterstained with hematoxylin (blue). Specific staining was localized to connective tissue and fibroblasts. View our protocol for Chromogenic IHC Staining of Paraffin-embedded Tissue Sections.

Detection of Fibronectin by Western Blot

DCN inhibits E-cadherin expression and EGFR pathway activation in IBC.a DCN suppresses E-cadherin expression and EGFR signaling in IBC cells. Expression levels of E-cadherin and EGFR are decreased in DCN-overexpressing MDA-IBC3, SUM190, SUM149, and BCX010 cells; also, the phosphorylation of EGFR (pEGFR) and ERK1/2 (pERK1/2) was suppressed in DCN-overexpressing IBC cell lines. Total ERK1/2 (tERK1/2) remains unchanged. GAPDH served as a loading control. b Treatment of IBC cells with DCN protein (4 or 8 μg/mL) for 2 h suppresses E-cadherin expression and EGFR pathway activation. Tubulin served as a loading control. c and d Western blot validation of E-cadherin and EGFR downregulation in tumor samples obtained from mammary fatpad transplantation of control or DCN-overexpressing MDA-IBC3 (c) or SUM149 (d) cells. e and f Immunohistochemical staining validation of E-cadherin and EGFR downregulation in tumor samples obtained from mammary fatpad transplantation of control or DCN-overexpressing MDA-IBC3 (e) or SUM149 (f) cells. Scale bar: 100 μm. g DCN inhibits EGFR signaling in IBC cells independently of EGF stimulation. DCN-overexpressing and control IBC cell lines were stimulated with 50 ng/mL EGF for the indicated number of hours, and total cell lysates were analyzed by western blotting. Both the total levels and the phosphorylation levels of EGFR and ERK1/2 were detected by western blotting. Tubulin served as a loading control. h DCN-mediated inhibition of E-cadherin does not affect expression of epithelial–mesenchymal transition markers. Cell lysates containing 40 μg of total protein were analyzed by western blotting with anti-E-cadherin, fibronectin, vimentin, and DCN antibodies. GAPDH served as a loading control.

Background: Fibronectin

Fibronectin is an extracellular matrix component that exists in different alternately spliced isoforms. Fibronectin mediates cell adhesion in its insoluble state but not as a soluble molecule. Fibronectins play a role in cell adhesion, migration, differentiation, and specific gene expression.
