      Question

      Product code: 91651

      Inquiry: To whom it may concern, I am looking for an antibody againt TK-1 for paraffin embedded mouse tumour tissue and was wondering whether you had any recommendations on positive and negative control tissue. I am specifically asking as the only information about positive control tissue I found is the human tonsil which is not applicable in mice . Many thanks for your help! Regards, Kathrin

      Answer

      Thank you for your enquiry.

      I'm sorry to confirm this antibody is not tested in IHC on paraffin sections (IHC-P). All tested species and applications covered by the 6 month guarantee are listed on the individual datasheets. These are updated as soon as we have any new information.

      The antibody has also been tested unsuccessfully in mouse, as stated on the datasheet. Therefore, regrettably this is not the most suitable antibody for your experiments.

      I can suggest one of the following two, tested in IHC-P and mouse, would be more suitable and will be covered by our 6 month guarantee in this application and species. I can recommend to review the online datasheets for further details:

      ab59271 Anti-Thymidine Kinase 1 antibody
      Tested in: IHC-P, WB, ELISA
      Rabbit polyclonal
      Reacts with:Human, Mouse
      https://www.abcam.com/index.html?datasheet=59271 (or use the following: https://www.abcam.com/index.html?datasheet=59271).

      ab76495 2563-1 Anti-Thymidine Kinase 1 antibody [EPR3193]
      Tested in: Flow Cyt, IP, WB, ICC/IF, IHC-P
      Rabbit monoclonal
      Reacts with: Human, Mouse
      https://www.abcam.com/index.html?datasheet=76495 (or use the following: https://www.abcam.com/index.html?datasheet=76495).

      According to the EST expression profile on the Unigen database link on the datasheet, in mouse the Tk1 protein is expressed quite highly in lymph node and several other tissues.
      http://www.ncbi.nlm.nih.gov/UniGene/ESTProfileViewer.cgi?uglist=Mm.2661

      I can therefore recommend to consider lymph node as a positive control tissue. You may wish to do some further literature searching for more information.

      Question

      I will be grateful if you could please answer my question regarding the 2x Anti-Thymidine Kinase 1 antibody which you show on your website.
      In particular, can you please let me know what is the difference between the rabbit monoclonal Anti-Thymidine Kinase [EPR3193] (ab76495), and the rabbit monoclonal Anti-Thymidine Kinase [EPR3194] (ab91651) one.
      I wish to use the Ab for immunohistochemistry on mouse tumor slices, but am unsure what the difference between the above 2 are.
      Thank you for attending to this email. I look forward to hearing from you.

      Answer

      Thank you for contacting Abcam.

      The main difference between ab76495 and ab91651 is that they will have different epitope recognition sites.

      Also for ab76495, we guarantee it to react with mouse and human tissue in the following applications, ICC/IF, WB, IP, IHC-P, Flow Cyt. Whereas ab91651 will react with human tissue but not mouse and rat and will work in the following applications WB, Flow Cyt, ICC/IF. Therefore ab91651 would not work for you since you wish to use the antibody on mouse sections.

      If there is anything else I can help you with, or if you need further selecting the most appropriate antibody for your experiments, please let me know.

      Question

      Dear Tech Support Team, Kindly advise which of the following will specificaly recognize Thymidine Kinase 1 and will not cross react with Thymidine Kinase 2. ab76495 ab57757 ab91651

      Read More
      Answer

      Thank you very much for your enquiry. Based on the immunogen sequences both Thymidine Kinase 1 (TK1) antibodies ab76495 and ab91651 are specific for TK1 and will not recognise TK2: The immunogen sequence for ab76495 is a peptide near the N-terminus (amino acids a-b) of human TK1 (SwissProt P04183), whereas ab91651 has its immunogen located at the C-terminus (amino acids y-z). These sequences do not share any homology with TK2. The TK1 antibody ab57757 has not been tested for a potential cross-reactivity with TK2. However, the immunogen is the full-length human TK1 which reveals no significant sequence similarity with human TK2 (SwissProt O00142). We therefore would not expect this antibody to cross-react with TK2. I hope this information is helpful to you. Please do not hesitate to contact us if you need any more advice or information.
