Target

  • Function

    Lineage-specific cytokine affecting the proliferation and maturation of megakaryocytes from their committed progenitor cells. It acts at a late stage of megakaryocyte development. It may be the major physiological regulator of circulating platelets.

  • Involvement in disease

    Defects in THPO are a cause of essential thrombocythemia (ET) [MIM:187950]. ET is inherited as an autosomal dominant trait which is characterized by elevated platelet levels due to sustained proliferation of megakaryocytes, and frequently lead to thrombotic and haemorrhagic complications.

  • Sequence similarities

    Belongs to the EPO/TPO family.

  • Domain

    Two-domain structure with an erythropoietin-like N-terminal and a Ser/Pro/Thr-rich C-terminal.

  • Cellular localization

    Secreted.

    Question

    we transafected and transfecting every week cMPL ( Receptor of Thrombopietin ) and put rTHPO into the cell culture to find out the bindung way. But the Problem ist that all the antobodys which we tried from you are not working in this way!

    Answer

    Thank you for your reply. If I am understanding your assay correctly, your cells are overexpressing a thrombopoietin receptor and you are incubating the cell culture with recombinant thrombopoietin to measure the binding efficacy. What type of recombinant thrombopoietin are you using? It would be very helpful if you could let me know the manufacturer and the catalog number. Have you tried a dot blot or WB with the recombinant protein to see if it is recognized by these antibodies? If you are able to detect the recombinant protein by itsself, there may be an issue with the receptor. I hope this helps, please let me know if you need any additional information or assistance.

    Question

    my cells are overexpressing a thrombopoietin receptor and we are incubating the cell culture with recombinant thrombopoietin to measure different things.

    Recombinant Human Thrombopoietin
    http://www.rndsystems.com/pdf/288-tp.pdf
    25 µg
    RundD Systems

    I trieted my cells with TPO and i have done a lot of WB with other antibodies and they are all fine,.

    But the antibodies which i bought from you do not function in WB; IF and FACS in my/ our hands.

    Read More
    Answer

    Thank you for your reply. I would still recommend checking if the antibodies bind to the recombinant protein in a dot blot assay. Because thrombopoietin is a secreted protein, it is very possible that it may be washed away from your cells during the staining process. If you are not satisfied with these antibodies, I will be more than happy to offer you a refund or a credit. Please let me know how you would like to proceed and I will be happy to help you further.

    Question

    I know that your company send me the details how to refund on off the antibodys. But I can’t do it via this way because it doesn’t fit with our computers here.

    Answer ur question:

    1) WB, high background, now Bands in the Western Blot

    IF, high background and none specific Binding

    FACS, only background but now speciffic binding

    2) Antibody dilutions

    ab93909 2µg/ml to 10µg/ml FACS, IF and WB

    ab128487 1: 50 bis 1:125 FACS, IF and WB

    3) 20µg of Protein been loaded tot he WB like all off my WB looks like

    4) I tried my old protocoll which I send u last time, we fixed the cells and +/-permeabilisation I tried too

    5) The second antiboys are perfect because i use them for other IF, WB and FACS too and there they are looking perfect

    Answer

    Thank you for your reply and the additional information.

    Regarding the refund, you would need to let your purchasing department know the information I had sent and they then should contact us so that the refund can be issued to you. I'm certain there is a way this can be arranged after your institution gets in touch with us.

    Regarding the other 2 antibodies:
    Your protocol in general looked fine and the antibody dilution used are more concentrated than the suggested range.

    You mentioned that you used Hela cells and I am wondering - since 3 anti-thrombopoietin antibodies seem not to be working - if this protein is expressed in Hela cells.

    It is mainly present in megakaryocytes and megakaryocytes-derived cells.
    http://www.proteinatlas.org/ENSG00000090534
    http://www.uniprot.org/uniprot/P40225

    The protein was shown to be present also in MCF7 cells, liver tissue, HepG2 cells.
    What other cell types have you tried, besides Hela cells? Would you be able to try any of the positive controls?

    I look forward to hear back from you and help you further.

    Question

    the answer to your question:
    The problems are not solved.
    All 3 antibodys which I bought sre not function in our hands.
    Teh andtibodys are:
    Ab128487
    Ab93909
    Ab40664
    My collegues and I checked them all 3 in 3 different methods.
    Western Blotting, FACS and IF
    We've been using Hela cells
    Protocolls from the WB, IF and FACS i put in a word file for you.
    I am not happy about this situation but I can't change the situation.

    Answer

    Thank you for contacting us.
    I am sorry to hear that these antibodies do not work as expected.

    According to the records in our system, the purchase of ab40664 has already been refunded and the case has been discussed and resolved.

    As for ab93909 and ab128487 I have a few more questions, if you don't mind:

    1) What is the actual problem you have encountered (e.g. no bands in WB, high background in ICC/IF etc)?
    I just wanted to mention that ab93909 has not been tested in FACS and ab128487 has not been tested in ICC/IF, but a discount code was issued to you for trying the latter antibody in ICC/IF.

    2) What antibody dilutions were used?

    3) How much protein was loaded onto the gel for WB analysis?

    4) For flow cytometry, did you try fixing and permeabilizing the cells?

    5) How well are the secondary antibodies working with other primary antibodies?


    I look forward to hear back from you and assist you further.
