Donkey Anti-Sheep IgG H&L (HRP) images

  • IHC image of Histone H3 staining in Human normal colon formalin fixed paraffin embedded tissue section*. The section was pre-treated using pressure cooker heat mediated antigen retrieval with sodium citrate buffer (pH6) for 30mins. The section was incubated with ab128012, 10µg/ml overnight at +4°C. An HRP-conjugated secondary (Ab6900, 1/1000 dilution) was used for 1hr at room temperature. The section was counterstained with haematoxylin and mounted with DPX.

    The inset negative control image is taken from an identical assay without primary antibody.

  • Ab6900 was used at dilution 1/20000 with the primary antibody ab30524 in WB. See the review on ab30524.
