Hi,	

I've heard rumors that there are systems for doing automated paraffin embedding AND that they orient tissue correctly.  Could someone (vendor, customer, anyone) please point me in the right direction?

Thank you!

My lab is FINALLY getting a Shandon Excelsior Tissue Processor.  I was wondering if anyone had any good protocols for the machine that would be great for mouse tissue...mainly the GI trac and liver and kidneys.

Thanks for all of your help!

Ya'll are right, this is a mess!

So, wouldn't this essentially mean that according to CLIA, since CAP is an acceptable private agency, they are giving the ok for CAP's decision on this?

Hi Vince, Sorry to take so long in getting back to you but things here
have been very busy. By CLIA's guidelines it sounds as though CAP has
removed themselves as an "acceptable" private accreditation when they
loosened the restrictions on grossing.  CLIA's database may not list
grossing but CLIA did publish a guideline to clarify their position:
This is the CLIA '88 guideline for high complexity testing personnel-
CLIA '88 493.1489
"On or before April 24 1995 (I) be a high school graduate or equivalent;
and (b) have documentation of training appropriate for the test
performed before analyzing patient specimens"...After that date it
requires an associate degree in a biological or chemical science or
medical laboratory technology -or- qualify as a medical technologist
with a bachelor's degree from an accredited institution -or- earned a
bachelor's degree in a chemical, physical, biologic or clinical
laboratory science.

A few years ago CLIA put out this interpretive guideline, (printed
below), to clear up the question of grossing.  As you see, it references
493.1498 (the above "high complexity guideline").  They basically sum up
that if you examine/describe the tissue for record noting color weight
or measurement then it is grossing and falls under 493.1498.  Tissue
processing as CAP calls it involves noting size and other
characteristics and qualifies as grossing under CLIA.

The new federal register CLIA interpretive guidelines appendix C subpart
M effective April 24, 2003 states in section 493.1461(e) "In the case if
gross examinations, the technical supervisor may delegate to individuals
qualified under 493.1498 the responsibility for the physical
examination/description, including color, weight, measurement, and other
characteristics of the tissue; or other mechanical procedures for which
a specific written protocol has been developed."

I hope this helps.  I don't know which side will budge first but I have
heard whisperings of CLIA doing something in the near future but what
ever it is it will probably only muddy the water further.  All I can say
is that CLIA is what happens when a government bureaucracy gets involved
with healthcare.

We actually use Acetone to deplasticise MMA sections. Only takes 2

In my experience, xylene is a rather poor solvent for PMMA.  It works
much faster at 60 degrees, but don't try heating flammable solvents in
your oven unless you are certain it is certified explosion-proof (most
paraffin ovens are not).  Even then, unless you have the oven in or at
least next to a fume hood, you'll get a lot of xylene vapors in the air
as a result of heating it.  I deplasticise PMMA with 2-methoxyethyl
acetate, which only takes a couple of hours at room temperature.  This
has a rather strong though not unpleasant odor, and should be used in
the hood.

And in return:

 

A surgeon, pathologist, physician, psychiatrist and radiologist go duck
hunting out on a pond.

 

As the first duck flies over head, the psychiatrist takes aim, ....but
doesn't fire.

"What the hell happened?" demands the surgeon (they're known for their
retiring manner)

"Well, says the psychiatrist, I know its a duck, and YOU know its a duck
- but does the duck know its a duck?"

 

The second bird flies over head, and the physician takes aim.....but
doesn't fire.

"What now???" roars the surgeon.

 

Well, says the physician, in a recent article I read in the New England
Journal of Medicine, 12% of ducks are actually 

Terns, and they're a protected species....

 

The third duck flies over, and the radiologist takes aim......then
paddles the boat further into the pond, then takes aim, then paddles
back a bit, then takes a further aim....and by this time the duck has
gone.

"Jesus wept!" explodes the surgeon, what the f*** were you doing?

 

Well, says the radiologist - every time I took aim, I realised that I
needed another view.

 

After lunch, they re-group for more hunting.

This time the surgeon gets out his double barrelled, gold plated
bazooka, blows his duck whistle - and as a flock of birds swarm over
head, he fires randomly and enthusiastically into the air. Objects rain
out of the sky. When he had finally finished blasting away to the
heavens - he turned to the pathologist and said: "row over to all those
bodies, and tell me if any of them was a duck"

We are currently retrieving animal tissue in a pressure cooker with a program of 125 degrees for 30 secs.  This protocol was taken from biocare but I'm sure this is for human tissue. Most of the tissue is retrieved with Biocare's Reveal (pH 6.0).  We are receiving some background staining of our negative controls whereas if we did not retrieve them, there is none.  We were staining for KI-67 which is a nuclear stain. I am using a tonsil for the control. The negative control showed some sporatic cytoplasmic staining on the Universal negative control from biocare as well as deionized water. Since then we have taken the temperature down to 115 degrees and increased the time to 25 minutes.  It seems to have decreased the cytoplasmic staining but there is still some lingering.  Anyone out there have any ideas??? I'm sure there is a better protocol for retrieving animal tissues. It has to be a time and temperature thing!

There are many who prefer the pressure cooker because of the low incubation period but I personally did not like it because of background issues as you describe and because some tissues peel-off the slides (too much heat).
  Because of that I ended using a HIER step in a buffer (citrate or EDTA depending on the pH) initially heated to boliling temperature in a microwave oven and the actual HIER to take place in a steamer during 20 minutes + 20 minutes out of the steamer. All problems were resolved this way. Give it a try.

You don't say what detection system you are using....However, if  you are 
using a Biotin-avidin/streptavidin detection, the background  may be due to the 
exposure of endogenous biotin by HIER.  You may need  to incorporate an 
appropriate blocking agent/system

You probably don't even need to get up to boiling for ki-67.  Try 30
minutes at 95 C in your pressure cooker.  Even on a "negative" control
you're bound to see something stain positive for ki-67, since it's a
proliferation marker... although it shouldn't be cytoplasmic.  I'm just
guessing there's got to be a cell or two in the tissue that's dividing.

control from biocare as well as deionized water. Since then we have
taken the temperature down to 115 degrees and increased the time to 25
minutes.  It seems to have decreased the cytoplasmic staining but there
is still some lingering.  Anyone out there have any ideas??? I'm sure
there is a better protocol for retrieving animal tissues. It has to be a
time and temperature thing!

Hi,	

I've heard rumors that there are systems for doing automated paraffin embedding AND that they orient tissue correctly.  Could someone (vendor, customer, anyone) please point me in the right direction?

Thank you!

This embedding instrument is manufactured by Sakura. It is not that the instrument orients the tissue, that is done when the tissues are placed in the cassette and held in place by a plastic frame that will be sectioned along with the tissue when the block is prepared. To function ideally it requires a special type of cassette and cassette holder (that is used alsao by the Sakura Xpress microwave tissue processor).

Can anybody tell me if there is another company besides Biocare that
offers an antibody cocktail with P504S, HMW CK, and p63? Does anybody
use the Biocare antibody detection system? I'd appreciate some feedback.
Thanks.

Hi,
  Ki67 staining in both human and mouse tissue in our lab works 
very well. We use steamer method 30min in Citra buffer.
