RPS20 / Ribosomal Protein S20 Antibody - Immunohistochemical analysis of RPS20 staining in human lung cancer formalin fixed paraffin embedded tissue section. The section was pre-treated using heat mediated antigen retrieval with sodium citrate buffer (pH 6.0). The section was then incubated with the antibody at room temperature and detected using an HRP polymer system. DAB was used as the chromogen. The section was then counterstained with hematoxylin and mounted with DPX.
