  Multiplex immunohistochemistry - Anti-Pancreatic Polypeptide antibody [EPR22853-61] (ab255827)

  Multiplex immunohistochemistry (Formalin/PFA-fixed paraffin-embedded sections) analysis of rat pancreas tissue.
  

  Panel A: Merged staining of anti-Pancreatic Polypeptide (ab255827, green), anti-Somatostatin 28 (Anti-Somatostatin 28 antibody [EPR3359(2)] ab111912, red) and DAPI (blue).

  Panel B: Anti-Pancreatic Polypeptide (green) stained on PP cells in rat pancreas islet.

  Panel C: Anti-Somatostatin 28 (red) stained on delta cells in rat pancreas islet.

  Panel D: Nuclear counter stain, DAPI (blue).

  Key protocol steps: The section was incubated in two rounds of staining with ab255827 (1/20000 dilution) and Anti-Somatostatin 28 antibody [EPR3359(2)] ab111912 (1/2000 dilution) for 30 mins at room temperature. Each round was followed by tyramide signal amplification with the appropriate fluorophore. Heat mediated antigen retrieval was used (Tris-EDTA buffer (pH 9.0, epitope retrieval solution 2) for 20 mins after every round of antibody/fluorophore staining.

  The immunostaining was performed on a Leica Biosystems BOND® RX instrument.

  A ready-to-use anti-Rabbit and Mouse Polymer HRP was used as a secondary.

  Fluorescence multiplex immunohistochemical analysis of the rat pancreas (Formalin/PFA-fixed paraffin-embedded sections).

  Panel A: merged staining of anti-SV2A (yellow; Opal™520), anti-GIP (magenta; Opal™570) and anti-Pancreatic Polypeptide (green; Opal™690) on rat pancreas.
  
  Panel B: anti-SV2A staining predominantly the beta cells in mouse pancreas islet.
  
  Panel C: anti-GIP staining the alpha cells in rat pancreas islet.
  
  Panel D: anti-Pancreatic Polypeptide staining the PP cells in rat pancreas islet.

  Nuclear DNA was labelled with DAPI (shown in blue). The section was incubated in three rounds of staining: in the order of Anti-SV2A antibody [EPR23500-32] ab254351 at 1/1000 dilution (0.48 μg/ml), Anti-GIP antibody [EPR20410] - BSA and Azide free ab271989 at 1/4000 dilution (0.25 μg/ml) and ab255827 at 1/10000 dilution (0.05 μg/ml) for 30 mins at room temperature. Each round was followed by a separate fluorescent tyramide signal amplification system.

  The immunostaining was performed on a Leica Biosystems BOND® RX instrument with an Opal™ 4-color kit. Image acquisition was performed with Leica SP8 confocal microscope.

  Heat mediated antigen retrieval with Tris-EDTA buffer (pH 9.0, epitope retrieval solution2) for 20 mins.
