anti-Fibronectin (EDA), mAb (blocking) (IST-9) (preservative free)

Product description: Monoclonal Antibody. Recognizes an epitope located in the EDA sequence of human cellular fibronectin (FN). Does not detect extracellular FN (plasma FN). Cross-reacts with mouse, rat, monkey, pig, dog, cow and chicken fibronectin EDA (according to literature). Isotype: Mouse IgG1. Clone: IST-9. Applications: ELISA, FUNC (Blocking), ICC, IHC, WB. Liquid. In 20mM sodium phosphate buffer, pH7.6 containing 150mM sodium chloride. Fibronectin is a major component of the extracellular matrix that binds to integrins, cell surfaces and various compounds including collagen, fibrin, heparin, DNA and actin. It occurs in two main forms: plasma and cellular fibronectin. EDA (Extra Domain A)-containing cellular fibronectin (EDA-FN) plays a major role in cell adhesion, growth, migration and differentiation and it is important for processes such as wound healing and embryonic development. It is associated with fibroblast differentiation by increasing alpha-SMA expression, collagen deposition, cell contractility and focal adhesion kinase (FAK) activation. EDA-FN promotes cell spread by interacting with the integrins alpha5-beta1, alpha4-beta1 and alpha9-beta1 and has been shown to promote angiogenesis, lymphangiogenesis and metastasis of colorectal tumors. In transformed or tumor-derived cells the EDA segment is about 10-times higher than in fibronectin from normal fibroblasts and it may therefore be a significant marker for malignancy.
