  • IHC image of OMA1 staining in human normal kidney 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 ab154949, 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.

  • All lanes : Anti-OMA1 antibody (ab154949) at 1 µg/ml

    Lane 1 : Human heart tissue lysate - total protein (ab29431)
    Lane 2 : Heart (Mouse) Tissue Lysate
    Lane 3 : Heart (Rat) Tissue Lysate

    Lysates/proteins at 25 µg per lane.

    All lanes : Goat Anti-Rabbit IgG H&L (HRP) (ab97051) at 1/50000 dilution

    Developed using the ECL technique.

    Performed under reducing conditions.

    Predicted band size: 60 kDa
    Observed band size: 58 kDa (why is the actual band size different from the predicted?)
    Additional bands at: 82 kDa (possible non-specific binding)

    Exposure time: 90 seconds

    The band observed at 58 kDa could potentially be a cleaved form of OMA1 due to the presence of a 13 amino acid transit peptide.

    This blot was produced using a 4-12% Bis-tris gel under the MOPS buffer system. The gel was run at 200V for 50 minutes before being transferred onto a Nitrocellulose membrane at 30V for 70 minutes. The membrane was then blocked for an hour using 2% Bovine Serum Albumin before being incubated with ab154949 overnight at 4°C. Antibody binding was detected using an anti-rabbit antibody conjugated to HRP, and visualised using ECL development solution ab133406
