Application Abreviews Notes
WB 1/500 - 1/1000. Predicted molecular weight: 62 kDa.
ELISA Use at an assay dependent concentration. Detection limit for recombinant tagged EAAT2 is approximately 0.03ng/ml.
IHC-P Use a concentration of 10 µg/ml. Perform heat mediated antigen retrieval with citrate buffer pH 6 before commencing with IHC staining protocol.


  • Function
    Transports L-glutamate and also L- and D-aspartate. Essential for terminating the postsynaptic action of glutamate by rapidly removing released glutamate from the synaptic cleft. Acts as a symport by cotransporting sodium.
  • Sequence similarities
    Belongs to the sodium:dicarboxylate (SDF) symporter (TC 2.A.23) family. SLC1A2 subfamily.

Anti-EAAT2 antibody images

  • IHC image of EAAT2 staining in Human normal cerebral cortex formalin fixed paraffin embedded tissue section, performed on a Leica Bond™ system using the standard protocol F. The section was pre-treated using heat mediated antigen retrieval with sodium citrate buffer (pH6, epitope retrieval solution 1) for 20 mins. The section was then incubated with ab77039, 10µg/ml, for 15 mins at room temperature and detected using an HRP conjugated compact polymer system. DAB was used as the chromogen. The section was then counterstained with haematoxylin and mounted with DPX.


    For other IHC staining systems (automated and non-automated) customers should optimize variable parameters such as antigen retrieval conditions, primary antibody concentration and antibody incubation times.

  • Anti-EAAT2 antibody (ab77039) at 1/500 dilution + recombinant tagged EAAT2 (the immunogen) at 0.2 µg/ml

    goat anti-mouse IgG (H&L)-HRP conjugate at 1/5000 dilution

    Predicted band size : 62 kDa
    Observed band size : 35 kDa (why is the actual band size different from the predicted?)
  • Anti-EAAT2 antibody (ab77039) at 1/500 dilution + HeLa cell lysate expressing EAAT2 at 25 µg

    goat anti-mouse IgG (H&L)-HRP conjugate at 1/2500 dilution

    Predicted band size : 62 kDa
    Observed band size : 70 kDa (why is the actual band size different from the predicted?)
    Additional bands at : 45 kDa,50 kDa. We are unsure as to the identity of these extra bands.
