Application Abreviews Notes
  • Application notes
    IHC-P: Use at a concentration of 1 µg/ml. Perform heat mediated antigen retrieval before commencing with IHC staining protocol.
    WB: 1/1000 when using colorimetric substrates such as BCIP/NBT, and 1/5000 for chemiluminescent substrates. Predicted molecular weight: 46 kDa. Dilution optimised using Chromogenic detection.

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

    • Function

      Inhibits urokinase-type plasminogen activator. The monocyte derived PAI-2 is distinct from the endothelial cell-derived PAI-1.
    • Sequence similarities

      Belongs to the serpin family. Ov-serpin subfamily.
    • Post-translational

      The signal sequence is not cleaved.
    • Cellular localization

      Cytoplasm. Secreted > extracellular space.

    • Ab47742 staining human normal temporal lobe. Staining is localized to the cytoplasm.
      Left panel: with primary antibody at 1 ug/ml. Right panel: isotype control.
      Sections were stained using an automated system DAKO Autostainer Plus , at room temperature. Sections were rehydrated and antigen retrieved with the Dako 3-in-1 AR buffer EDTA pH 9.0 in a DAKO PT Link. Slides were peroxidase blocked in 3% H2O2 in methanol for 10 minutes. They were then blocked with Dako Protein block for 10 minutes (containing casein 0.25% in PBS), then incubated with primary antibody for 20 minutes, and detected with Dako Envision Flex amplification kit for 30 minutes. Colorimetric detection was completed with diaminobenzidine for 5 minutes. Slides were counterstained with Haematoxylin and coverslipped under DePeX. Please note that for manual staining we recommend to optimize the primary antibody concentration and incubation time (overnight incubation), and amplification may be required.
    • Anti-SerpinB2/PAI-2 antibody (ab47742) at 1 µg/ml + Human placenta tissue lysate - total protein (ab29745) 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: 46 kDa
      Observed band size: 49 kDa
      why is the actual band size different from the predicted?
      Additional bands at: 72 kDa. We are unsure as to the identity of these extra bands.

      Exposure time: 1 minute

      SerpinB2/PAI-2 contains a number of potential glycosylation sites (SwissProt) which may explain its migration at a higher molecular weight than predicted.
