• 

  Immunocytochemistry/Immunofluorescence: Fibronectin Antibody - BSA Free TA336854 - NIH3T3 cells were fixed in 4% paraformaldehyde for 10 minutes and permeabilized in 0.05% Triton X-100 in PBS for 5 minutes. The cells were incubated with anti- TA336854 at 1 ug/ml overnight at 4C and detected with an anti-rabbit Dylight 488 (Green) at a 1:1000 dilution for 60 minutes. Nuclei were counterstained with DAPI (Blue). Cells were imaged using a 100X objective and digitally deconvolved.

• Background: Fibronectin EDA (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).

• Note: This Fibronectin antibody is useful for Immunocytochemistry/Immunofluorescence, Western Blot, and IHC-paraffin embedded sections. In ICC/IF, cytoplasmic staining was observed in HeLa cells. In Western Blot, a band is seen ~262 kDa representing Fibronectin. In IHC-P, staining was observed in the cytoplasm and extracellular space of mouse prostate tissue. Prior to immunostaining paraffin tissues, antigen retrieval with sodium citrate buffer (pH 6.0) is recommended.
