To work with these kinds of specimens, for years and years in hospital used
Goody curler paper (sorry I don't know anything about hairdressers curling
hair but they can be had at drugstore/department store where they sell hair
products). Get 500 or so for a couple of dollars.
Wet them in the fixative. Mentally divide the paper into thirds each way so
you have a mental image of 9 square areas in a 3x3 array. Carefully put
your fragments or shavings or small biopsies in center area. Using forceps,
fold up the bottom third. Fold down top third. Fold in left hand and right
hand thirds to end up with square that fits in cassette and won't unfold.
When processed, while unfolding you know where those bits are. Either in
the center area or the single area folded over top of it.
It silly, its dirt cheap, its not high-tech, its not cool or sophisticated,
but for us in my lab, we never would loose any bits or pieces. Maybe we
were lucky with the set-up but if I put 8 minute fragments of a gastric
biopsy in, I felt confident and always could locate those 8 fragments easily
for embedding. Bags I'd have trouble in creases and corners and even too
with mesh cassettes. Processed well and any problem I thought might have
(like getting paper shreds into block for bad sectioning), just never
happened.
I still think those Goody curl papers are the best. I've never had them
fail to give me back every single bit of irreplaceable tissue I put in. And
pretty economically.

Dear All,
We wish to do a double immunostain for CD34 and active caspase 3 on
paraformaldehyde fixed mouse tissues. The cd34 primary is rat monoclonal
anti cd34 The caspase 3 primary is a rabbit polyclonal antibody.
We would like to use the Dako Envision G/2 kit for double staining, however
this kit is for mouse or rabbit primaries only. When we do a single stain
for cd34, we use a Rabbit anti Rat IgG as a linking antibody between the
primary and secondary antibody (Dako Envision plus kit for rabbit
primaries) and this works well on our tissues in our experience.
My question is: Can I add this linking antibody step to the method and
still use the Envision G/2 kit?
Does anyone have any experience with this sort of thing or any different
ideas on doing double staining using these particular antibodies?
All ideas and comment appreciated as always.
Cathy

Hello!
I'm looking for a marker for lymphatic endothelium, which should have
wide species cross-reactivity, and works with paraffin-embedded,
formalin-fixed sections.
Chemicon/Upstate seems to have several promising products (two monos and
one polyclonal) but there's little information available on these.
Anyone have experience on these or other suitable antibodies?
With best regards,
Mikael Niku

To those of you who received the questionnaire and have not answered it

Dear Mr. or Ms
We are working in a small lab from Canarias Island (Spain). We work with
goat brain with manual procedure, our problems are several in the
processing:
1. We obtain very dry blocks, when we try to cut with the microtome,
the tissues are fragile and it is impossible to obtain the correct
tissue.
2. When "we get proper block" (we can cut better the tissue), then we
try to put in the float, the tissue appears like a white colour in the
slide. After when we finish the stain process (hematoxyline-eosina and
kluver barrera both of them) the tissues are not attached on the glass
slides.
I explain you in fast way our protocol:
1. Fixation: the whole brain is embedded in Formol 10% (1 week
minimum)
2. Dehydration: 80: etanol 30 minutes; 96: 30 min x 2 times; 100 : 30
min x 5 times; xylene 1 hour x 2 times
3. Tissue embedding in paraffin. In cassetes with pure paraffin all
night- Only 1 step other times 2 changes in paraffin 1 hour
4. Cut with microtome at 8 um, slide with polylisine.
5. Stain process (Hematoxyline-Eosine and kluver barrera)
Thank a lot!!

We have the Peloris rapid tissue processor. It is xylene free but does
not use microwaves. It uses isopropyl alcohol after the reagent alcohol
to remove all traces of water and then goes straight to the paraffin
from there. Amazingly, and contrary to everything we have been taught,
this works!
It processes small biopsies in approximately 1 hour. Shave biopsies
take approximately 2 hours and the larger specimens 4 to 6 hours. We
find the processing to be at least equal to routine processing and in
many cases, superior to it. Because it does not use xylene, the tissues
are not hard and brittle as they can sometimes be with routine
processing.
It has two separate retorts which can run two separate runs at the same
time. We are able to process our specimens throughout the day instead
of everything being processed at night as in the past. It has greatly
improved our TAT.
The Peloris tracks the number of blocks run and, based on this, tells
you when to change the various solutions. As a result, we have saved a
significant amount of money on reagents.
We are extremely happy with ours.

Greetings Leila
If you are fixing the whole brain by immersion the interior morphology
won't be very good. I suggest cutting the brain into 1 cm slices and
fixing these for 1-2 weeks. You will be able to see enough of the
anatomy to know the order of the slices.
If you must process the brain whole you will need to fix by vascular
perfusion to see much (any) of the interior anatomy and your processing
will have to be much longer.
The rest of your schedule does not allow enough time for dehydration,
especially on a whole brain. The tissue does not stick to the slides
because it was not properly dehydrated so the paraffin does not infiltrate.
On the other hand, all night in hot paraffin is too long and produces
brittle tissue.
I suggest the following for 1 cm slices, not a whole goat brain.
After fixation, wash in water for several hours or overnight.
50% ethanol 1-2 hours. Agitation of the tissue duringhis and subsequent
steps is highly desirable.
70% ethanol 1-2 hours.
95% ethanol 1 hour.
100% ethanol 2 changes 1 hour each.
1:1 mix of 100% ethanol:xylene 1 hour.
Xylene, 2 changes 1 hour each.

We use a fair amount of the biopsy bags and one can purchase them for
half the price that was quoted in the last histo-net. We purchase ours
from Thermo Fisher and still get them for $205.64 for 1000 bags. We do
not use the blue sponges due to the fact that we noticed reagent
carryover in our processor which compromised our quality of tissue
processing. Also, we have found that if one does not make certain the
mesh cassettes are "submerged" in formalin a piece of tissue may stick
to the top of the cassette or in a corner and not get proper processing.
That is why for now we have been utilizing the nylon bags and fine them
easy and efficient to use.

I've seen a protocol for isopropanol-processing with an IPA-temperature
about 74 degrees. That is near the boilingpoint and means rather a boiling
out of the tissue than acting as intermedium. Similar protocols are found
with the microwave-techniques. I think there is no principal difference in
reaching the temperature.
What I'm a little confused about is the fact, that usually recommended
temperatures for tissueprocessing don't raise above 62 degrees. So how does
this influence staining, ihc-staining etc.?
What are the temperatures in your protocol?
What does the community think about this issue?

Betreff: [Histonet] Peloris Processor
We have the Peloris rapid tissue processor. It is xylene free but does
not use microwaves. It uses isopropyl alcohol after the reagent alcohol
to remove all traces of water and then goes straight to the paraffin
>from there. Amazingly, and contrary to everything we have been taught,
this works!
It processes small biopsies in approximately 1 hour. Shave biopsies
take approximately 2 hours and the larger specimens 4 to 6 hours. We
find the processing to be at least equal to routine processing and in
many cases, superior to it. Because it does not use xylene, the tissues
are not hard and brittle as they can sometimes be with routine
processing.
It has two separate retorts which can run two separate runs at the same
time. We are able to process our specimens throughout the day instead
of everything being processed at night as in the past. It has greatly
improved our TAT.
The Peloris tracks the number of blocks run and, based on this, tells
you when to change the various solutions. As a result, we have saved a
significant amount of money on reagents.
We are extremely happy with ours.

In the past, we have disposed of paraffin trimmings in regular trash and
old or broken, stained and unstained slides in non-biohazard glass
disposal unless they are from a suspected CJD case. We are reviewing
this procedure and cannot find documentation to support our policy, in
fact we have found some indication that TB may still be viable. What is
everyone else doing for disposal of their paraffin debris and slides for
disposal?
Thanks for your input!
