  • Anti-BRN3B / POU4F2 antibody (ab128849) at 1 µg/ml + Rat Retina Tissue Lysate at 25 µg

    Goat Anti-Rabbit IgG H&L (HRP) (ab97051) at 1/10000 dilution

    Developed using the ECL technique.

    Performed under reducing conditions.

    Predicted band size: 43 kDa
    Observed band size: 43 kDa
    Additional bands at: 23 kDa (possible non-specific binding), 53 kDa (possible non-specific binding)

    Exposure time: 4 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 ab128849 overnight at 4°C. Antibody binding was detected using an anti-rabbit antibody conjugated to HRP, and visualised using ECL development solution.
