The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
% SDS-PAGE. Purified from bovine plasma
Additional notesLyophilized bovine Fibronectin although stable at room temperature for 1 week, should be stored desiccated below -18°C. Upon reconstitution Fibronectin should be stored at 4°C between 2-7 days and for future use below -18°C. Please prevent freeze-thaw cycles.

Preparation and Storage
Stability and Storage
Shipped at 4°C. Store at -20°C. Store under desiccating conditions.
pH: 7.50 Constituents: 0.79% Tris HCl, 0.58% Sodium chloride
ReconstitutionPurified Cow Fibronectin has a tendency to form insoluble aggregates upon reconstitution. We suggest to reconstitute the 1mg Fibronectin with a chaotropic agent such as urea at room temperature at a concentration of 0.2mg/ml using sterile water.
Let stand 1-2 hours.
Upon reconstitution ab125170 should be stored at 4°C between 2-7 days and for future use below -18°C. Please prevent freeze-thaw cycles.

FunctionFibronectins 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. Anastellin 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.
Tissue specificityPlasma 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.
Involvement in diseaseGlomerulopathy with fibronectin deposits 2
Developmental stageUgl-Y1, Ugl-Y2 and Ugl-Y3 are present in the urine from 0 to 17 years of age.
Post-translational modificationsSulfated. It is not known whether both or only one of Thr-2064 and Thr-2065 are/is glycosylated. Forms 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). Phosphorylated by FAM20C in the extracellular medium. Proteolytic processing produces the C-terminal NC1 peptide, anastellin.
