Product Overview
Clone 26F78 is a rabbit monoclonal antibody that recognizes fibronectin (gene FN1) in human, mouse and rat samples and is validated for flow cytometry, ICC/IF, IHC and Western blot. The predicted molecular weight is 272.3 kDa, and the supplier reports an observed band at about 272 kDa.
Fibronectin (FN1) is a large extracellular matrix glycoprotein that binds integrins, collagen, fibrin and heparin. It exists as a soluble plasma form and as insoluble fibrils in tissues, and it supports cell adhesion, migration, wound healing and embryonic development. Fibronectin is a common matrix marker in studies of fibrosis and tissue repair.

Samples with a confirmed band (WB): human U-87MG cells, human HepG2 cells, rat liver tissue, mouse liver tissue.
Recommended loading (WB): 20–40 µg of total protein per lane.
Conditions in the example images (WB): 5–20% gradient SDS-PAGE under reducing conditions, 30 µg lysate per lane, transfer to nitrocellulose membrane, blocking in 5% non-fat milk, primary antibody at 1:500 overnight at 4 °C, HRP-conjugated secondary antibody at 1:500, ECL detection.
Samples with confirmed staining (IHC): human colorectal adenocarcinoma tissue, human liver cancer tissue.
Recommended antigen retrieval: heat-mediated, in TE buffer (pH 9.0); citrate buffer (pH 6.0) can be used instead.
Conditions in the example images (IHC): heat-mediated antigen retrieval in EDTA buffer (pH 8.0).
Immunogen
Synthetic peptide based on the sequence of human fibronectin.
Reactivity Notes
The supplier lists reactivity with human, mouse and rat. UniProt describes fibronectin as a secreted protein. Tissue expression noted by UniProt (human): Expressed in the inner limiting membrane and around blood vessels in the retina (at protein level). The samples tested by the supplier (listed above) are a practical starting point for positive controls.
