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 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 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.

Plasma Fibronectin is a secreted dimeric protein. It is involved in cell adhesion, migration, wound healing, and other cellular processes. Human Fibronectin shares 92% and 90% amino acid sequence homology with bovine and mouse Fibronectin, respectively.
R&D Systems personnel manually curate a database that contains references using R&D Systems products.
The data collected includes not only links to publications in PubMed,
but also provides information about sample types, species, and experimental conditions.
