I have worked with animal tissues for well over 18 years and I agree
with other previous posters here, that your problem is most likely the
fixation at 4oC.

Subject: [Histonet] mouse heart chatter upon sectioning...
Whenever I process (whole)mouse hearts, the tissue chatters upon
sectioning. The tissue is usually fixed overnight in 10%nbf at 4C
before processed. I tried different processing times. The last time I
processed hearts, I processed them for 5 hours total no vaccum. Should
I decrease the processing time even lower than that? I am afraid of
underprocessing. I have to section the entire heart from top to bottom,
so I really need some advice.
(open system) Processor Set Up:
1 - fix (if tissue fixed overnight, skip #1 & #2 stations)
2 - fix
3 - 70%
4 - 80%
5 & 6 - 95%
7 & 8 - 100%
9 & 10- Xylene Sub. - Clear-rite
11 & 12-Paraffin stations
