Hi Michelle,

I worked for a company called WARD'S Natural Science in Rochester, NY; they produce/provide science education materials.  I can't say I ever produced the internal ear slide myself, but I can recall others in the department working on something similar.  I would give them a call at 1-800-962-2660 and ask to speak with a tech or supervisor in the microscope slides department.  Even if they don't normally carry what you're looking for, I am sure they would be happy to try and provide you with what you want.

I hope you find what you're looking for!  Best of luck.

Wow that is going to be a tuff one, back in the day I tried to cut
Petris pyramid from the inter ear and was told it was the
densest/hardest bone in
the body and it sure seemed to be. Even decalcified we had to embed it
in plastic and use permanent tungsten carbide D profile knives to cut
any sections. I am not at the university anymore so can't access those
slides or I would try to help you out.

Hello! please see below inquiry from a colleague. Thanks! Atoska


Our histology class is looking for replacements for old Turtox (Guinea
Pig) Internal Ear, cochlea slides and was wondering if anyone knew a
company who supplied these slides or tissue blocks? I don't think it has
to be guinea pig but I haven't been able to locate internal ear slides
from any species. Any help would be appreciated. Thanks!

Yep that is what I do, I use the plastic containers I get salad or other
stuff in I would throw away, fill it and freeze it, I add some water to
it and put the blocks on the frozen tray and they get cold and hydrated
at the
same time.

we use something like this:

E=1&highlight=414004-256

we keep several sizes in the freezer, depending on�how many blocks we
need to cut.� The nice thing is that it is cheap and you can hydrate
your blocks
at the same time you are chilling them.

Oh my, I agree with Liz, your samples are way too thick and your process
is way too short. Even for 3-4mm thickness bone I fix for 24-72 hours
and then
decal in 5% formic acid usually overnight on a platform shaker. I assume
RDO decals a lot faster but not that fast, I do not use RDO because I
think the formic acid which may be slower better preserves the antigens
for IHC.

Subject: SPAM-LOW: RE: [Histonet] Canine bone sectioning trouble

Overall your fixation, decalcification and processing cycle is too
short. The sample size is really big, why do you need it so thick? I
would first of all let the samples fix longer 24 to 48 hours or I would
trim them so that they are about 3-5 mm in thickness. Either way I like
fixing bone samples for 24 to 48 hours. I'm not that accustomed to
using RDO decal it is hydrochloric acid based and is quicker but even
bone that size would take a while to decal. We normally use a formic
acid based decal and a sample size that large my take up to 2 weeks to
decal. Also to process a sample that size I would be at 4 to 6 hours a
station. We frequently process porcine and goat knees in 2 x 3 blocks
the samples are quite thick about a cm in thickness and we will process
them at 4 to 6 hours a station.

My recommendation would be to decal the larger cube of bone for a period
of time until you can section through it. I would then cut a 3-4 mm
thick piece off the cube and process it at 1 hour per station.

Subject: [Histonet] Canine bone sectioning trouble

Hello out there...

We are having trouble sectioning canine bone. The samples are bone
marrow cubes approximately 2cm thick and 1in wide. They were fixed for
15 hours in 10% NBF and decaled for 30 - 45 mins in RDO rapid
decalcifier. They were faced in and then surface decaled again for
about 30 mins. When sectioned, much of the marrow was missing and the
bone was torn and shredded. We thought that maybe the samples had not
been fixed sufficiently so refixed overnight in 10% NBF again. The
samples were then reprocessed as they had been originally. The
processing schedule used was: 70% EtOH 30mins, 80% EtOH 30mins, 95% EtOH
x 2, 30mins each, 100% EtOH x 2, 30 mins each, xylene x 2, 45 mins each,
paraffin x 4, 40 mins each. Again they were faced in and decaled for
another 30 mins or so. This time as soon as the sections are placed on
the water bath (38 degrees) they explode and/or come apart so severely
sections can almost not be picked up. If sections are even obtainable
they are of horrible quality. Does anyone have any suggestions? Thank
you so much in advance!

I do not bake my unstained slides for IHC controls and store them at
4dc. I
bake them just before use. They do last longer this way but Richard is
right, there is no telling because it all depends on the fixation,
target protein stability and storage conditions. It is always a good
idea to cut
fresh sections if the stored unstained sections do not perform as
expected.

We bake our unstains at 60 degrees C. for 30 minutes prior to filing at
RT. There is no set rule for stability. It all depends on fixation, the
nature of the protein target, and storage conditions. I've seen
absolutely spectacular immunoreactivity on unstained slides stored at RT
for 20 years
(and longer) and I've seen reduced immunoreactivity in unstained slides
stored for as little as 4 weeks. We will always attempt to stain
unstained slides when available; however, if the lesion or tumor is
negative, and
there is no internal control, you better cut fresh sections.

are they good for to use for immunohistochemistry.
