  Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded sections) - Anti-CD4 antibody [RM1013] (ab288724)

  Immunohistochemical analysis of paraffin-embedded Human tonsil tissue labelling CD4 with ab288724 at 1/1000 (0.55 μg/ml) followed by a ready to use LeicaDS9800 (Bond™ Polymer Refine Detection). Positive staining on the human tonsil. The section was incubated with ab288724 for 30 mins at room temperature. The immunostaining was performed on a Leica Biosystems BOND^® RX instrument. Counterstained with Hematoxylin.
  

  Secondary antibody only control: Secondary antibody is a ready to use LeicaDS9800 (Bond™ Polymer Refine Detection).

  Immunohistochemistry (Frozen sections) - Anti-CD4 antibody [RM1013] (ab288724)

  IHC image of CD4 staining in a section of frozen human tonsil* performed on a Leica Biosystems BOND^® RX instrument using the standard protocol. The section was fixed in 10% paraformaldehyde (10 min) prior to staining. The section was incubated with ab288724, 0.5 ug/ml, for 15 mins at room temperature and detected using an HRP conjugated compact polymer system. DAB was used as the chromogen. The section was then counterstained with haematoxylin and mounted with DPX. The inset secondary-only control image is taken from an identical assay without primary antibody.
  

  For other IHC staining systems (automated and non-automated) customers should optimize variable parameters such as antigen retrieval conditions, primary antibody concentration and antibody incubation times.
