Our Abpromise guarantee covers the use of ab49405 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 a concentration of 0.1 µg/ml. Recommended use at a low concentration otherwise high background staining may be observed
WB Use a concentration of 1 µg/ml. Detects a band of approximately 45 kDa (predicted molecular weight: 45 kDa).
ICC/IF 1/250.


  • FunctionRequired for the transition into meiosis for both female and male germ cells. In female germ cells, required for premeiotic DNA replication and subsequent events in meiotic prophase.
  • Tissue specificityExpressed specifically in testis.
  • Post-translational

  • Anti-Stra8 antibody (ab49405) at 1 µg/ml + Brain (Mouse) Tissue Lysate at 10 µg

    Goat polyclonal to Rabbit IgG - H&L - Pre-Adsorbed (HRP) at 1/3000 dilution

    Performed under reducing conditions.

    Predicted band size : 45 kDa
    Observed band size : 45 kDa
    Additional bands at : 55 kDa,85 kDa. We are unsure as to the identity of these extra bands.
  • All lanes : Anti-Stra8 antibody (ab49405) at 1 µg/ml

    Lane 1 : CHO overexpressing Mouse Stra8 lysate
    Lane 2 : CHO Negative Control Lysate

    Lysates/proteins at 1 µl per lane.

    Goat Anti-Rabbit IgG H&L (HRP) (ab97051) at 1/10000 dilution
    Developed using the ECL technique

    Performed under reducing conditions.

    Predicted band size : 45 kDa
    Observed band size : 60 kDa (why is the actual band size different from the predicted?)

    Exposure time : 1 minute

    Ab49405 recognizes tagged overexpressed Stra8 protein which has an expected molecular weight of 60 kDa.

  • IHC image of Stra8 staining in mouse testis formalin fixed paraffin embedded tissue section, performed on a Leica BondTM system using the standard protocol B. 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 ab49405, 0.1µg/ml, for 15 mins at room temperature. A goat anti-rabbit biotinylated secondary antibody was used to detect the primary, and visualized using an HRP conjugated ABC 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.
