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 mouseTo 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 smoothIncubate 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.
