Beschreibung

Allgemeine Beschreibung

Fibronectin (FN) is an extracellular adhesion molecule and it is involved in many cellular processes, including tissue repair, embryogenesis, blood clotting, and cell migration/adhesion.

Fibronectin exists in two main forms: 1) as an insoluble glycoprotein dimer that serves as a linker in the ECM (extracellular matrix), and; 2) as a soluble disulphide linked dimer found in the plasma (plasma FN). The plasma form is synthesized by hepatocytes, and the ECM form is made by fibroblasts, chondrocytes, endothelial cells, macrophages, as well as certain epithelial cells.

Fibronectin sometimes serves as a general cell adhesion molecule by anchoring cells to collagen or proteoglycan substrates. FN also can serve to organize cellular interaction with the ECM by binding to different components of the extracellular matrix and to membrane-bound FN receptors on cell surfaces. The importance of fibronectin in cell migration events during embryogenesis has been documented in several contexts, e.g.: 1) mesodermal cell migration during gastrulation can be blocked by injection of Arg-Gly-Asp (RGD) tripeptides that block cellular FN receptors (integrins); 2) injection of anti-FN antibodies into chick embryos blocks migration of precardiac cells to the embryonic midline, and; 3) the patterns of FN deposition in developing vertebrate limbs determines the patterns of precartilage cell adhesion to the ECM, thereby specifying limb-specific patterns of chondrogenesis. {D.

Anwendung

Research Category
Zellstruktur

Research Sub Category
ECM-Proteine

Anti-Fibronectin Antibody detects level of Fibronectin & has been published & validated for use in ELISA, IF, RIA, WB, IH(P).

Immunohistochemistry: 1:80 dilution for immunofluorescent staining of fresh frozen bovine skin and liver tissues. Acetone or methyl-carnoy fixation is also reactive.

Immunohistochemistry on paraffin embedded tissues requires light fixation in 2% PFA, 4% formalin (less than 90 minutes), acetone or methyl-carnoy fixation; traditional formalin fixation is not recommended. Antigen retrieval is HIER citrate buffer; detection is via enhanced enzymatic methods only.

Immunoblotting: 1:1000 of 2% deoxycholate + 10% SDS, 6M urea extracted bovine cell cultures (Kinsella, 2000). Antibody demonstates the appropriate twin bands at ~220kDa.

Radioimmunoassay

ELISA

Optimal working dilutions must be determined by end user.
