Application Abreviews Notes
  • Application notes
    IHC-P: Use at a concentration of 5 µg/ml.
    WB: Use at a concentration of 1 µg/ml. Detects a band of approximately 50 kDa (predicted molecular weight: 45 kDa).

    Not yet tested in other applications.
    Optimal dilutions/concentrations should be determined by the end user.
  • Target

    • Function

      Ligand-gated ion channel with relatively high calcium permeability. Binding to ATP mediates synaptic transmission between neurons and from neurons to smooth muscle. Seems to be linked to apoptosis, by increasing the intracellular concentration of calcium in the presence of ATP, leading to programmed cell death.
    • Sequence similarities

      Belongs to the P2X receptor family.

      Developed using the ECL technique.

      Performed under reducing conditions.

      Predicted band size: 45 kDa
      Observed band size: 50 kDa
      why is the actual band size different from the predicted?
      Additional bands at: 58 kDa. We are unsure as to the identity of these extra bands.

      Exposure time: 2 minutes

      P2X1 contains a number of potential glycosylation sites (SwissProt) which may explain its migration at a higher molecular weight than predicted. Furthermore, the 50 kDa band observed is comparable to the molecular weight seen with other commercially available antibodies to P2X1.
    • IHC image of ab74058 staining in Human Hippocampus formalin fixed paraffin embedded tissue section, performed on a Leica BondTM 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 ab74058, 5µg/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.
