  • IHC image of VAPA 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 ab96584, 1µg/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.

  • All lanes : Anti-VAPA antibody (ab96584) at 1/1000 dilution (12% SDS PAGE)

    Lane 1 : H1299 whole cell lysate
    Lane 2 : NIH3T3 whole cell lysate

    Lysates/proteins at 30 µg per lane.
