  • Anti-Placental lactogen antibody (ab15554) at 1/100 dilution + Human recombinant hPL at 0.1 µg

    HRP conjugated donkey anti-rabbit IgG
    developed using the ECL technique

    Performed under reducing conditions.

    Predicted band size : 25 kDa
    Observed band size : 25 kDa
    Additional bands at : 10 kDa,14 kDa,45 kDa. We are unsure as to the identity of these extra bands.

    Exposure time : 5 minutes

  • ab15554 at 1/200 staining human BeWo (placenta choriocarcinoma) cells by ICC/IF. The cells were paraformaldehyde fixed and blocked with BSA prior to incubation with the antibody for 30 minutes. A rhodamine conjugated goat anti-rabbit antibody was used as the secondary. The left hand panel of the image shows DAPI counterstain.

  • Anti-Placental lactogen antibody (ab15554) at 1/25 dilution + Human placenta lysate

    Predicted band size : 25 kDa
    Observed band size : 23 kDa (why is the actual band size different from the predicted?)
