Any body doing MI in mice and staining heart slices with tetrazolium at @37°C?

Most often I am facing problem, heart slices distort / contract in tetrazolium incubation @37°C. Staining itself has no problem, but the tissue structure.

Briefly:

  • Heart is harvested from mouse
  • To have smooth cutting / slices, heart is wrapped in plastic bag (sealed) in -20°C for around 20-25min, it becomes semi solid.
  • Slicing of heart (1mm thick) - At this point slices are flat and smooth
  • Incubate slices in pre-warmed tetrazolium at 37°C at hot plate / heating pad for 20 minutes
  • (this step distorts the tissue structure (not any more flat)
  • Incubate in Pre-warmed 10% formalin for 20min on heating pad.
  • Photos.
  • Can any body suggest the remedy for this.

    Note: This does not matter whether MI was performed or not.
