Application Notes
In Western Blot, a band is seen at ~262 kDa representing Fibronectin. The observed molecular weight of the protein may vary from the listed predicted molecular weight due to post translational modifications, post translation cleavages, relative charges, and other experimental factors. In ICC/IF, cytoplasmic staining was observed in HeLa cells. In IHC-P, staining was observed in the cytoplasm and extracellular space of mouse prostate tissue. Antigen retrieval with 10mM sodium citrate buffer (pH 6.0) is recommended. In Simple Western only 10 - 15 uL of the recommended dilution is used per data point. Separated by Size-Wes, Sally Sue/Peggy Sue. The 12-230kDa separation system and EZ Standard Pack 5 are recommended for detecting human Fibronectin using Simple Western.
Please Note: Optimal dilutions of this antibody should be experimentally determined.

Background: Fibronectin

Fibronectin (FN-EDA, FN, fibronectin 1) is a glycoprotein that is involved in cell adhesion as well as cell migration processes such as embryogenesis, wound healing, host defense and metastasis. Fibronectin appears to be an important factor in the ability of cancerous cells to metastasize by inducing matrix metalloproteinases (MMPs). In a study of human laryngeal carcinoma cells, researchers showed that FN-induced expression of MMP-9 increased the DNA binding activity of transcription factors NF-kappa-B, Activator protein-1 and Specificity protein-1 to the promoter region (PMID: 20638438). Additionally, a study of renal cell cancer showed that the mRNA expression of fibronectin 1 was higher in patients with renal cell cancer as compared to patients with healthy kidneys. This disparity in mRNA expression levels could potentially be used to determine the aggressiveness of renal cell cancer as well as indicate the progression of the disease in patients (PMID: 20860816). Furthermore, a knockdown study of endogenous FN in the A431-III cell line showed a significant decrease of the migratory and invasive activity of the cells as well as an inhibition of secreted MMP-9 (PMID: 21036738).
