  • Image acquisition with NIS-ELEMENTS (Nikon).
• Tissue: mouse heart
• • Obtain mouse heart mouse and wash it with PBS.
  • Fix tissue in 15ml falcon tube with 4% PFA ON at 4°C.
  • Wash the fixed heart with water.
  • Embed tissue in paraffin.
  • Cut the tissue using a microtrom and put it into slides.
  • Desparaffinize the tissue in the slide (from xylene to water).

  • Wash tissue 2x for 5min with PBS 0.1% triton.
  • Incubate tissue with secondary goat anti-rabbit AF488 antibody (Invitrogen, A11008, 1911238) diluted 1:200 in PBS 1% BSA solution for 1h at RT.
  • Wash cells 2x for 5min with PBS.
  • Wash tissue 2x for 3min with PBS 0.1% triton.
  • Wash tissue 2x for 3min with PBS.
  • DAPI counterstain for 5min at RT.

  • Image acquisition with NIS-ELEMENTS (Nikon).

Notes:

ABIN1386389 did not label recombinantly expressed PKP2-FLAG in transfected HL1 cells. A hypothesis could be that antibody recognizes the murine protein in mouse heart samples but not the human sequence of the vector (transfected HL1).

Background: Plakophilins 1, 2, 3 and 4 (PKP1-4) influence development and participate in linking cadherins to cytoskeletal intermediate filaments. Plakophilins 1-4 contain arm-repeat (armadillo) domains, and localize to nuclei and cell desmosomes (cell-cell junctions found in suprabasal layers of stratifying epithelia that undergo mechanical stress). Plakophilin-1 mediates increases in desmosomal protein content, desmosome assembly, and regulation of cell migration. Plakophilin-2 is important for desmosome assembly and is an essential morphogenic factor and architectural component of the heart. Plakophilin-3 plays a role in both desmosome-dependent adhesion and signaling pathways. Plakophilin-4 is a component of desmosomal adhesion plaques that regulates junctional plaque organization and cadherin function.
