Application Abreviews Notes
WB Use at an assay dependent concentration. Detects a band of approximately 52 kDa (predicted molecular weight: 47 kDa).
IHC-P 1/50. Perform heat mediated antigen retrieval before commencing with IHC staining protocol.


  • Function
    High affinity receptor for activated thrombin coupled to G proteins that stimulate phosphoinositide hydrolysis. May play a role in platelets activation and in vascular development.
  • Tissue specificity
    Platelets and vascular endothelial cells.
  • Sequence similarities
    Belongs to the G-protein coupled receptor 1 family.
  • Post-translational
    A proteolytic cleavage generates a new N-terminus that functions as a tethered ligand.
    Phosphorylated; probably mediating desensitization prior to the uncoupling and internalization of the receptor.
  • Cellular localization
    Cell membrane.

  • Anti-PAR1/Thrombin Receptor antibody (ab32611) at 1 µg/ml + Human Platelet (Human adult normal cell line) Whole Cell Lysate at 10 µg

    Goat polyclonal to Rabbit IgG - H&L - Pre-Adsorbed (HRP) at 1/3000 dilution

    Developed using the ECL technique.

    Performed under reducing conditions.

    Predicted band size: 47 kDa
    Observed band size: 52 kDa
    why is the actual band size different from the predicted?
    Additional bands at: 87 kDa. We are unsure as to the identity of these extra bands.

    Exposure time: 12 minutes

    PAR1/Thrombin Receptor  contains a number of potential glycosylation sites (SwissProt) which may explain its migration at a higher molecular weight than predicted.

Thank you for contacting us in regards to the Anti-Thrombin Receptor antibody (ab32611) and sorry for the late reply.

As discussed over the phone, I have enquired as to whether we are able to provide the immunising peptide used to raise the antibody ab32611. Unfortunately, this is something we are not able to do.

I am sorry that I could not be of more help in this instance. If you have any further questions, please do not hesitate to ask.

Thank you for contacting us.

The Uniprot http://www.uniprot.org/uniprot/P25116 database shows, the active part of protein "human Proteinase-activated receptor 1" has amino acid sequence between 42-425, so antibodies specific to this region would be recognising the active form of protein. Based on this assumption ab32611 would be the best choice.

I hope this information is helpful to you. Please do not hesitate to contact us if you need any more advice or information.
