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.

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
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.

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.

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.
