  • 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.
    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 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.
  • Involvement in disease

    Glomerulopathy with fibronectin deposits 2
  • Sequence similarities

    Contains 12 fibronectin type-I domains.
    Contains 2 fibronectin type-II domains.
    Contains 16 fibronectin type-III domains.
  • Developmental stage

    Ugl-Y1, Ugl-Y2 and Ugl-Y3 are present in the urine from 0 to 17 years of age.
  • Post-translational

    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.

When transferring large proteins precipitation or incomplete transfer of the high MW protein can occur. I have included some tips about large protein transfer from our Western Blot guide below and have links this as well. I hope this is of help to you. Note on transfer of large and small proteins The balance of SDS and methanol in the transfer buffer, protein size, and gel percentage can affect transfer efficiency. The following modifications will encourage efficient transfer. Large proteins (>100 kD) For large proteins, transfer out of the gel may be very slow, just as they run slowly within the gel during separation. If blotting a large protein, be sure to run your samples in a low-concentration gel, 8% or less. These will be very fragile, so handle carefully. Large proteins will tend to precipitate in the gel, hindering transfer. Adding SDS to a final concentration of 0.1% in the transfer buffer will discourage this. Methanol tends to remove SDS from proteins, so reducing the methanol percentage to 10% or less will also guard against precipitation. Lowering methanol in the transfer buffer also promotes swelling of the gel, allowing large proteins to transfer more easily. Methanol is only necessary if using nitrocellulose. If using PVDF, methanol can be removed from the transfer buffer altogether, and is only needed to activate the PVDF before assembling the gel/membrane sandwich. Choose wet transfer overnight at 4°C instead of semi-dry transfer. The following reference discusses a gel and buffer system that allows transfer of proteins as large as 500 kD: Bolt and Mahoney, High-efficiency blotting of proteins of diverse sizes following sodium dodecyl sulfate–polyacrylamide, gel electrophoresis. Analytical Biochemistry 247, 185–192 (1997). http://(https://www.abcam.com/index.html?pageconfig=resource&rid=11404)

The doublet when using serum may be result of mild proteolysis or incomplete reduction. I would recommend making sure protease inhibitors are added to your lysis buffer directly before use and heat your samples in laemmli buffer for 20 minutes at 72C.

Vielen Dank für diese weiteren Informationen.
Es tut mir Leid, dass Sie Probleme mit diesem Antikörper hatten. Wie am Telefon besprochen, habe ich eine kostenlose Ersatzlieferung für Sie in Auftrag gegeben. Sie hat die Referenznummer 123456 und sollte morgen bei Ihnen ankommen.
Ich kann die Blots bezüglich der KO Mäuse gut gebrauchen: Das gibt mir den Rückhalt gegenüber dem Labor nicht nur das betroffene Lot zurück zurufen, sondern dass die Lots in Produktion noch einmal genauer angeschaut werden!
Ich wünsche Ihnen viel Erfolg mit Ihren Projekten. Bitte melden Sie sich wieder bei uns, falls es weitere Fragen oder Probleme gibt.

Unfortunately the discount code is only applicable before purchasing the antibodies to be tested. The discount code is not applicable neither for testing the isotype control as it has already been tested with Flow Cytometry, and therefore is not eligible for our antibody evaluation program (Abreview). However, you can still send us the results obtained from testing both primaries with Flow Cytometry and submit them in the form of an Abreview and earn 120 Abpoints exchangeable for rewards. If an image is submitted as well you’ll get 100 extra Abpoints. To find out more about our Abpoints, please refer to the next link: https://www.abcam.com/index.html?pageconfig=loyalty_about&viapagetrap=abpoints Just for your information I would like you to encourage having a look at our Flow Cytometry protocols online, where you could find useful information about the Flow Cytometry protocol as well as helpful tips: https://www.abcam.com/index.html?pageconfig=popular_protocols I hope this information was helpful. Please do not hesitate to contact us if you need further advice or information.

We have not tested this specifically. I would assume it detects both but not familiar with the research of how you would be able to distinguish the plasma and cellular forms (by cell type?).

Thank you for your enquiry. I would recommend that you aliquot your antibodies and only dilute when you are ready to use the antibody. Also, I would recommend that you dilute them into PBS, not TBS. Unfortunately, we do not have a protocol specifically for dilutions. Do be careful about how much you aliquot though, because you want to avoid doing a lot of freezing and thawing of the same aliquot. So try to aliquot enough for one use. I hope this information helps, please do not hesitate to contact us if you need any more advice or information.

Thank you for your enquiry. First, let me direct you a very informative website about IHC called IHC World. The web address is www.ihcworld.com. You can search that website for streptavidin, and then click on the Immunohistochemistry Introduction link. From there you can read about the different methods including the ABC and LSAB(involves streptavidin) methods. Here is what the site says about the streptavidin method: Streptavidin, derived from streptococcus avidini, is a recent innovation for substitution of avidin. The streptavidin molecule is uncharged relative to animal tissue, unlike avidin which has an isoelectric point of 10, and therefore electrostatic binding to tissue is eliminated. In addition, streptavidin does not contain carbohydrate groups which might bind to tissue lectins, resulting in some background staining. LSAB is technically similar to standard ABC method. The first layer is unlabeled primary antibody. The second layer is biotinylated secondary antibody. The third layer is Enzyme-Streptavidin conjugates (HRP-Streptavidin or AP-Streptavidin) to replace the complex of avidin-biotin peroxidase. The enzyme is then visualized by application of the substrate chromogen solutions to produce different colorimetric end products. The third layer can also be Fluorescent dye-Streptavidin such as FITC-Streptavidin if fluorescence labeling is preferred. A recent report suggests that LSAB method is about 5 to 10 times more sensitive than standard ABC method. I hope this information helps, please do not hesitate to contact us if you need any more advice or information.
