[Histonet] formalin fixed mouse ears-help
Since you did not say what your processing schedule is for these ears, I
suspect infiltration in paraffin is not very good so extend the time there
and use a vacuum. This still denser tissue even though it appears very
thin, and those layers can be a problem. Try at least three changes under
vacuum. Hopefully you have vacuum and pressure on your processor, and
don't add heat to the processing solvents, these are skinny dry tissues to
4. Lower the temperature of the water bath and don't over soak a trimmed
block on ice water.
Nothing is silly or simple if you are having problems. Good luck
