products description :
Principle of the Assay: This kit was based on sandwich enzyme-linked immune-sorbent assay technology. Anti-Fibronectin polyclonal antibody was pre-coated onto 96-well plates. And the biotin conjugated anti-Fibronectin polyclonal antibody was used as detection antibodies. The standards, test samples and biotin conjugated detection antibody were added to the wells subsequently, and wash with wash buffer. Avidin-Biotin-Peroxidase Complex was added and unbound conjugates were washed away with wash buffer. TMB substrates were used to visualize HRP enzymatic reaction. TMB was catalyzed by HRP to produce a blue color product that changed into yellow after adding acidic stop solution. The density of yellow is proportional to the Fibronectin amount of sample captured in plate. Read the O.D. absorbance at 450nm in a microplate reader, and then the concentration of Fibronectin can be calculated. Background: Fibronectin is a high-molecular weight (~440kDa) glycoprotein of the extracellular matrix, belongs to a family of high molecular weight glycoproteins that are present on cell surfaces, in extracellular fluids, connective tissues, and basement membranes. Two major forms of fibronectin exist: a plasma soluble form and a cellular form. It plays a major role in cell adhesion, growth, migration, and differentiation, and it is important for processes such as wound healing and embryonic development. Fibronectin has been implicated in carcinoma development, and also acts as a potential biomarker for radioresistance.

ncbi summary :
This gene encodes fibronectin, a glycoprotein present in a soluble dimeric form in plasma, and in a dimeric or multimeric form at the cell surface and in extracellular matrix. Fibronectin is involved in cell adhesion and migration processes including embryogenesis, wound healing, blood coagulation, host defense, and metastasis. The gene has three regions subject to alternative splicing, with the potential to produce 20 different transcript variants. However, the full-length nature of some variants has not been determined.

uniprot summary :
Function: Fibronectins bind cell surfaces and various compounds including collagen, fibrin, heparin, DNA, and actin. Fibronectins are involved in cell adhesion, cell motility, opsonization, wound healing, and maintenance of cell shape. Involved in osteoblast compaction through the fibronectin fibrillogenesis cell-mediated matrix assembly process, essential for osteoblast mineralization. Participates in the regulation of type I collagen deposition by osteoblasts. Ref.38 Ref.40 Ref.44 Ref.50Anastellin binds fibronectin and induces fibril formation. This fibronectin polymer, named superfibronectin, exhibits enhanced adhesive properties. Both anastellin and superfibronectin inhibit tumor growth, angiogenesis and metastasis. Anastellin activates p38 MAPK and inhibits lysophospholipid signaling. Ref.38 Ref.40 Ref.44 Ref.50. Subunit structure: Mostly heterodimers or multimers of alternatively spliced variants, connected by 2 disulfide bonds near the carboxyl ends; to a lesser extent homodimers. Interacts with FBLN1, AMBP, TNR, LGALS3BP and COL13A1. Interacts with FBLN7 . By similarity. Interacts with COMP. Interacts with S.aureus fnbA. Interacts with TNR; the interaction inhibits cell adhesion and neurite outgrowth . By similarity. Interacts with FST3. Ref.36 Ref.38 Ref.39 Ref.41 Ref.42 Ref.47. Subcellular location: Secreted extracellular space extracellular matrix. Tissue specificity: Plasma FN (soluble dimeric form) is secreted by hepatocytes. Cellular FN (dimeric or cross-linked multimeric forms), made by fibroblasts, epithelial and other cell types, is deposited as fibrils in the extracellular matrix. Ugl-Y1, Ugl-Y2 and Ugl-Y3 are found in urine. Ref.16 Ref.35. Developmental stage: Ugl-Y1, Ugl-Y2 and Ugl-Y3 are present in the urine from 0 to 17 years of age. Ref.16 Ref.35. Post-translational modification: Sulfated.It is not known whether both or only one of Thr-2064 and Thr-2065 are/is glycosylated. Ref.16 Ref.26 Ref.35 Ref.58Forms covalent cross-links mediated by a transglutaminase, such as F13A or TGM2, between a glutamine and the epsilon-amino group of a lysine residue, forming homopolymers and heteropolymers (e.g. fibrinogen-fibronectin, collagen-fibronectin heteropolymers).Phosphorylation sites are present in the extracellular medium.Proteolytic processing produces the C-terminal NC1 peptide, anastellin. Involvement in disease: Glomerulopathy with fibronectin deposits 2 (GFND2) [MIM:601894]: Genetically heterogeneous autosomal dominant disorder characterized clinically by proteinuria, microscopic hematuria, and hypertension that leads to end-stage renal failure in the second to fifth decade of life.Note: The disease is caused by mutations affecting the gene represented in this entry.
