Human/Rat Fibronectin Antibody

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 0.1 µg/mL of Sheep Anti-Human/Rat Fibronectin Antigen Affinity-purified Polyclonal Antibody (Catalog # AF1918) followed by HRP-conjugated Anti-Sheep IgG Secondary Antibody (HAF016). 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.

Fibronectin in A549 Human Cell Line.

Fibronectin was detected in immersion fixed A549 human lung carcinoma cell line untreated (top panel) or treated with 10 ng/mL TGF-beta (Catalog # 240-B, lower panel) for 48 hours using Sheep Anti-Human/Rat Fibronectin Antigen Affinity-purified Polyclonal Antibody (Catalog # AF1918) at 10 µg/mL for 3 hours at room temperature. Cells were stained using the NorthernLights™ 557-conjugated Anti-Sheep IgG Secondary Antibody (red; Catalog # NL010) and counterstained with DAPI (blue).

Fibronectin in Human Liver.

Fibronectin was detected in immersion fixed paraffin-embedded sections of human liver using Sheep Anti-Human/Rat Fibronectin Antigen Affinity-purified Polyclonal Antibody (Catalog # AF1918) at 10 µg/mL overnight at 4 °C. Tissue was stained using the Anti-Sheep HRP-DAB Cell & Tissue Staining Kit (brown; Catalog # CTS019) and counterstained with hematoxylin (blue). Specific staining was localized to plasma membranes in hepatocytes. View our protocol for Chromogenic IHC Staining of Paraffin-embedded Tissue Sections.
