Properties

Applications

Our Abpromise guarantee covers the use of ab8217 in the following tested applications.

The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.

Application Abreviews Notes
IHC-P Use at an assay dependent concentration. Antigen retrieval is not essential but may optimise staining.
WB Use at an assay dependent concentration. Cross reacts with an intracellular 60 kDa protein of unknown identity like other anti-CD45RA MAbs.
Flow Cyt Use a concentration of 1 - 4 µg/ml.

ab170192 - Mouse monoclonal IgG2b, is suitable for use as an isotype control with this antibody.

 
IP Use at an assay dependent concentration.

Target

  • Function
    Protein tyrosine-protein phosphatase required for T-cell activation through the antigen receptor. Acts as a positive regulator of T-cell coactivation upon binding to DPP4. The first PTPase domain has enzymatic activity, while the second one seems to affect the substrate specificity of the first one. Upon T-cell activation, recruits and dephosphorylates SKAP1 and FYN. Dephosphorylates LYN, and thereby modulates LYN activity.
  • Involvement in disease
    Severe combined immunodeficiency autosomal recessive T-cell-negative/B-cell-positive/NK-cell-positive
    Multiple sclerosis
  • Sequence similarities
    Belongs to the protein-tyrosine phosphatase family. Receptor class 1/6 subfamily.
    Contains 2 fibronectin type-III domains.
    Contains 2 tyrosine-protein phosphatase domains.
  • Domain
    The first PTPase domain interacts with SKAP1.
  • Post-translational
    modifications
    Heavily N- and O-glycosylated.
  • Cellular localization
    Membrane. Membrane raft. Colocalized with DPP4 in membrane rafts.

    ab8217 CD45RA antibody [MEM-56] ab27290 CD45RA antibody [B-C15] (FITC) ab30476 CD45RA antibody [F8-11-13] ab38439 CD45RA antibody [LT45-M5] What epitopes do these antibodies recognize; do they recognize glycosylated dependent epitopes?

    Thank you for your patience in this matter. In regards to ab30476 (CD45RA antibody [F8-11-13] (Biotin)), the originator does not know which epitope this antibody is recognizing. However, information available in the literature suggests that it reco...
