• Product name

    Anti-Phosphothreonine-Proline antibody
  • Description

    Rabbit polyclonal to Phosphothreonine-Proline
  • Host species

  • Specificity

    This antibody specifically reacts to proteins containing phosphothreonine-proline motifs, it also reacts to the phosphoserine-proline motif to a similar degree (pT-P and pS-P motif). The antibody does not react to phosphothreonine, phosphoserine or phosphotyrosine. The antibody will selectively recognize the phosphothreonine-proline motif of MBP, which is the site of phosphorylation by ERK1/ERK2.
  • Tested applications

    Suitable for: ELISA, WB, IPmore details
  • Species reactivity

    Reacts with: Species independent
  • Immunogen

    Chemical/ Small Molecule: TpP conjugated to KLH.

  • Positive control

    • WB: Mouse brain lysate ELISA: Phosvitin or casein
  • General notes

    The antigen is based on N-acetyl-pT-K-pY-NH2. The pT-X-pY sequence is considered to be the motif for some active MAPKs.

Thank you for your reply.

Kate is currently not in the office but I will try to help with your enquiry as best I can. If you were to test this antibody in IF you would be eligible to take part in the Abtrial testing program.

The way that this program works it that you would purchase ab9344 as normal, test the antibody in IF and let us know of the results through an Abreview (no matter whether positive or negative) you would then be eligible to claim the value of ab9344 off any product in our catalogue. More information on this offer can be found here:


Please note that the antibody to be tested must be purchased, tested, the Abreview submitted and the free product claimed within a 4 month period.

If you would be interested in participating in this scheme please do let me know as a discount code needs to be issued prior to the purchase of ab9344.

I hope this information has been of help. If you require any further information please do not hesitate to contact us again.

Thank you for contacting Abcam. The antibody ab9344 is guaranteed to work in ELISAs and so would most probably work in the application that you intend to use it for, however you would have to work out the exact condition for you experiment, but I think it should be ok. If there is anything else I can help you with, please let me kn

Thank you for contacting us. We have anti glycine or anti- proline antibodies in our catalogue. The catalogue numbers are ab9344, ab9345, ab37067, ab9442 and ab37087. We unfortunately do not have antibodies available specifically raised against proline-glycine-proline short peptide. I would like to recommend checking the Biocompare website which has an excellent antibody search facility that includes many suppliers. The links are: www.biocompare.com http://www.biocompare.com/ProductCategories/2045/Antibodies.html Elastin proteins also have repeating units of proline and glycine residues. So probably monoclonal antibodies against part of Elastin will be helpful e.g. ab97963 and ab51599. Although these do not exactly match however it will help to widen your search. I hope this information is nevertheless helpful to you. Please do not hesitate to contact me if you have any further questions in this regard.
