  Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded sections) - Anti-CD31 antibody [RM1006] (ab281583)

  IHC image of ab281583 staining CD31 in mouse lung formalin fixed paraffin embedded tissue sections, performed on a Leica Biosystems BOND® RX instrument. The section was pre-treated using heat mediated antigen retrieval using Bond™ Epitope Retrieval Solution 2 (pH 9.0) for 20 minutes. The section was then incubated with ab281583 at 1:4000 dilution (0.116 μg/ml) for 30 mins at room temperature and detected using an HRP conjugated compact polymer system (Bond™ Polymer Refine Detection). DAB was used as the chromogen. Positive staining was obtained on blood vessels in mouse lung. The section was then counterstained with haematoxylin and mounted with DPX. No primary antibody was used in the secondary only control (shown on the inset).
  

  
  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.

Heat mediated antigen retrieval was conducted for 32min with DISCOVERY cell conditioning solution (CC1) 100°C, pH8.5. ab281583 anti-CD31 was incubated at 37°C for 16min.

  Sections were counterstained is with Hematoxylin II. Image inset shows absence of staining in secondary antibody only control.

  Customers are encouraged to optimise antigen retrieval conditions, antibody concentration, incubation times and temperature for best results in their own IHC assay workflow (automated and manual)
