Immunohistochemistry-Paraffin: H.O.H.(TM) (Human on Human) Immunodetection Kit [HOH-3000-NB] - Serial sections of human kidney (FFPE). Left image shows strong, specific staining (brown) using human anti-cytokeratin primary antibody and detected with HOH-3000. Right image is a negative control showing absence of staining (no background) with the omission of just the primary antibody in the HOH-3000 assay. Both sections counterstained with hematoxylin (blue nuclei).
