  • 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?)
