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

    Performed under reducing conditions.

    Predicted band size : 35 kDa
    Observed band size : 35 kDa
    Additional bands at : 148 kDa,42 kDa,71 kDa. We are unsure as to the identity of these extra bands.

    Exposure time : 8 minutes

    This blot was produced using a 10% 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 5% Bovine Serum Albumin before being incubated with ab125236 overnight at 4°C. Antibody binding was detected using an anti-rabbit antibody conjugated to HRP, and visualised using ECL development solution.
