  • 功能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.
    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.
  • 组织特异性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.
  • 疾病相关Glomerulopathy with fibronectin deposits 2
  • 序列相似性Contains 12 fibronectin type-I domains.
    Contains 2 fibronectin type-II domains.
    Contains 16 fibronectin type-III domains.
  • 发展阶段Ugl-Y1, Ugl-Y2 and Ugl-Y3 are present in the urine from 0 to 17 years of age.
  • 翻译后修饰Sulfated.
    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.

Anti-Fibronectin antibody [Fn-3] 图像

  • ICC/IF image of ab18265 stained HeLa cells. The cells were 4% formaldehyde fixed (10 min) and then incubated in 1%BSA / 10% normal goat serum / 0.3M glycine in 0.1% PBS-Tween for 1h to permeabilise the cells and block non-specific protein-protein interactions. The cells were then incubated with the antibody (ab18265, 1µg/ml) overnight at +4°C. The secondary antibody (green) was Alexa Fluor® 488 goat anti-mouse IgG (H+L) used at a 1/1000 dilution for 1h. Alexa Fluor® 594 WGA was used to label plasma membranes (red) at a 1/200 dilution for 1h. DAPI was used to stain the cell nuclei (blue) at a concentration of 1.43µM.

  • ab18265 staining Fibronectin in BAE cells by Immunocytochemistry/ Immunofluorescence. The cells were fixed in paraformaldehyde, permeabilised in Triton X-100 and then blocked using 1% serum for 30 minutes at 24°C. Samples were then incubated with primary antibody at 1/500 for 1 hour at 24°C. The secondary antibody used was a goat polyclonal conjugated to Alexa Fluor® 546 used at a 1/1000 dilution.

Thank you for your enquiry. The Fn-3 clone recognizes a determinant on cellular but not plasma fibronectin. I am assuming this is the EDB region, although this is not explicitly stated in the reference I have. I will send this reference to you in ...
