Overview

  • Product name

    Anti-Transferrin Receptor antibody [B349 (DF1513)]
    See all Transferrin Receptor primary antibodies

  • Description

    Mouse monoclonal [B349 (DF1513)] to Transferrin Receptor

  • Host species

    Mouse

  • Specificity

    This antibody reacts with the transferrin receptor, a 180-190 kD transmembrane glycoprotein which exists as a 95 kD homodimer with interchain disulfide bond. The specificity of these antibodies, as demonstrated by immunoprecipitation, are equivalent to OKT9, B3/25 and BerT9. This antibody reacts with many proliferating cells in both normal and neoplastic tissues. It also reacts with renal tubular epithelium, islets of Langerhans, scattered cells in the anterior pituitary, hepatocytes and most tissue macrophages.

  • Species reactivity

    Reacts with: Human

  • Immunogen

    Cell line KG1.

  • Positive control

    • Tonsil.

  • General notes


    This antibody is an indicator of proliferation activity. It also has prognostic significance when typing tumors, such as leukemias and lymphomas.

Properties

Target

  • Function

    Cellular uptake of iron occurs via receptor-mediated endocytosis of ligand-occupied transferrin receptor into specialized endosomes. Endosomal acidification leads to iron release. The apotransferrin-receptor complex is then recycled to the cell surface with a return to neutral pH and the concomitant loss of affinity of apotransferrin for its receptor. Transferrin receptor is necessary for development of erythrocytes and the nervous system (By similarity). A second ligand, the heditary hemochromatosis protein HFE, competes for binding with transferrin for an overlapping C-terminal binding site. Positively regulates T and B cell proliferation through iron uptake (PubMed:26642240).
    (Microbial infection) Acts as a receptor for new-world arenaviruses: Guanarito, Junin and Machupo virus.

  • Involvement in disease

    Immunodeficiency 46

  • Sequence similarities

    Belongs to the peptidase M28 family. M28B subfamily.
    Contains 1 PA (protease associated) domain.

  • Post-translational
    modifications

    N- and O-glycosylated, phosphorylated and palmitoylated. The serum form is only glycosylated.
    Proteolytically cleaved on Arg-100 to produce the soluble serum form (sTfR).
    Palmitoylated on both Cys-62 and Cys-67. Cys-62 seems to be the major site of palmitoylation.

    Question

    3T3 lysates were negative in western blotting but so were 293 cells. We need an antibody positive for human transferrin receptor and negative for mouse.

    Question

    Would these products
    (ab1086, ab84036, ab9179, ab8598) detect Trf1 and Trf2?

    Read More
    Answer

    Thank you for your enquiry.

    We have not tested these products (ab1086, ab84036, ab9179) for cross reactivity with Trf2. However, based on immunogen sequence (ClustalW analysis, Score 23.0), we do not expect to see any cross reactivity whatsoever. However, there might be a possibility that ab8598 could react but we do not supporting data.

    I hope this information will help settle any concerns that you may have.

    Question

    I recently ordered the Anti-Transferrin Receptor antibody [B349 (DF1513)] (ab8598) from you. I have used it at 1:100, in 1% Milk TBST at 4 oC overnight followed by a secondary anti mouse HRP antibody 1:3000. I got no signal from the antidody, a few weak bands but nothing that I think was specific. Are there any specific conditions that this antibody should be usedunderso I canget it working a little better? Any information will be very much appreciated.

    Read More
    Answer

    Thank you for your inquiry.


    We have confirmedTFR expression in Hep G2, HEL 92.1.7 and TF-1 whole cell lysates using thefollowing conditions:

    Load 50 ug of total protein
    Blocking with 5% milk TBST for one hour at room temperature
    Primary: 1:100 incubate for one hour at room temperature with 5% milk TBST
    Secondary: in-house secondarygoat anti-mouse IgG-HRP: at 1:3000. Incubate for 45 minutes
    10% gelPVDF membranes

    If the above does not help, I can help if you provide more detail on the protocol:

    1. What samples are you testing?
    2. How much protein were you loading?
    3. What did you do for the blocking step?
    4. Have you confirmed the secondary has been performing?
    5. Did you run a loading control?
    6. Did you load a positive control?

    I hope this information helps. Please contact us with any other questions.

    Question

    I spoke to you today about the Anti-transferrin receptor antibody (ab1086) that did not work for my cell line (Jurkat). I would like to thank you for offering to send us a replacement.  I would be interested in trying the western blot again with ab8598 (the antibody that you recommended, which seems to have worked quite well with a number of cell lines).   Please let me know if you need any further information from me.

    Answer

    Thanks for following up with me. I would be happy to send you a vial of ab8598. I will just need to locate your initial order for ab1086 to process your request. Do you have the purchase order number or Abcam order reference number associated with the purchase of ab1086? Thanks!

    Answer

    Further to contact with the source of this antibody I have determined that this antibody does not perform well by western blotting. Given that this antibody was detailed as working by western blotting on our datasheets I would like to firstly apolagise and secondly offer you a credit note to the value of one vial of this antibody. Please e-mail me details of your original purchase including the order number and date of purchase and I will arrange for our accounts team to raise you the credit.

    Answer

    Thank you for your enquiry. I am sorry to hear that you have been having difficulties with this antibody. I have read your technical questionnaire and I have a few comments. Whilst we recommend that our customers use a tonsil preparation as a positive control I have performed a brief search of the literature and it appears that the use of Caco-2 cells is quite standard for the studying of Transferrin Receptor expression. I would like to recommend that you quantitate the mass of protein that you are loading onto the gel; presently there is no way of determining the mass of protein loaded per well. This will provide a better idea of whether the antibody is capable of detecting its target by immunoblotting. It would also help if you ponceau stain your membrane following transfer. This will enable you to determine the integrity of the protein and the success of transfer. Alternatively a parallel loading control western blot would serve to confirm the integrity and transfer of your samples. I will submit your question regarding the antibody only targeting the native form of this protein to the lab and get back to you shortly. I appreciate your patience.
