Hi,
    Don't use a microwave. At least an hour in a 60 degree oven should do the
trick. Enzymatic predigestion for antigen retrieval is usually harsh. If
you are
using this try something different. 3% H2O2 is also harsh on many tissues try
.03% for a longer time. If any tissue has survived your heating steps these
suggestions may help keep it on the slides.
Good Luck
