[Histonet] 11. plant anatomy - sectioning problems (yvan lindekens)

[Downs, Heather M.]

 If possible and you can use resins, try Spurr's.  It was specifically designed
to use with plants and vegetables, and you can cut as thin as 1 micron.  The
resin is easy to use, is less toxic that epon, and has great penetration.

In case anyone wants the HT and HTL exam statistics for July-Dec 2006.

If you want information on other categories or other years, go to:
http://www.ascp.org/Certification/ForProgramDirectors/default.aspx

Couple of notes first:
- Range of scores is easiest question 100 to hardest question 999. Same with
practical exam score numbers.
- Minimul score of 400 degree of difficulty is required to pass each part.
- Both the practical (PRAC) and the multiple choice questions (MCQ) must be
passed, in order to pass the complete (COMP) exam. However, each candidates
has 5 tries, so they may pass one part one year, and try again the next year
- which is why the numbers don't match up.
- NAACLS is the National Accrediting Agency for Clinical Laboratory
Sciences. It is the agency that accredits HT and HTL programs. ASCP records
the number of NAACLS students taking the exam for the first time.
- The other category on the website is Total # Taking Exam. This would be
NAACLS students taking it for the first time, repeating NAACLS students, OJT
(on the job training) candidates taking it for the first time, and OJT
candidates repeating the exam.
- The "Non-NAACLS" category is one I extrapolated. It is the total # minus
the NAACLS first timers. That leave the OJT first timers, OJT repeaters, and
NAACLS repeaters (small number).

Hi all.  I am asking this question on behalf of a colleague.  She wishes to
measure rat uterine smooth muscle cell volume over gestation and would like to
have a marker that would delinate the smooth muscle plasma membrane.  I have
looked at some of my Masson trichrome-stained mouse placental sections and this
*might* be helpful for her; however, I was thinking one of you might know of a
good lectin or antibody marker.  Like I said, she works on rat tissue, but I
wouldn't mind receiving some advice on mouse uterine smooth muscle cell markers,
too.
 
Thanks a bunch!

What about alpha smooth muscle actin, most anti-human SMA antibodies will
cross react with rodent.  If she is planning on both rat and mouse tissues
then I would choose a rabbit antibody to smooth muscle actin.  The one that
we use works in both rat and mouse, its from abcam ab5694.

Along those same lines mouse anti-SMAalpha clone 1A4 works very well 
for SMC in mouse and human. To avoid having to use a MOM kit I use 
the EPOS version from DAKO which is VERY pricey but worth every penny 
for the gorgeous and clean result in mouse tissues (it can also be 
diluted and doesn't need to be used neat as  recommended by 
manufacturer).

Hi all,

I'm trying to cut some plant samples but I have lots
of problems with the samples containing even the
smallest amount of wood (f.e. young white deadnettle
stems - Lamium album L.).

A thickness of 15 micron is the thinnest I can get,
without the ribbon scattering longitudaly after only a
few sections. Whiping the blade with a cloth moisted
with some xylene solves the problem, but only for
another 2 or 3 sections... I use a Leica-Jung Autocut
1140 and Feather S/R/N 35 blades.

Cutting at veeeeeeryyyyy looooow speed gives slightly
better results but still not good enough!

When sectioned on a sliding microtome(Reichert-Jung
Hn-40, Feather S/R/N 35 blades, declination angle +/-
130°), the sections are okay, but I would like to use
a rotary. 

Samples were fixed in AFA, processed by hand using an
ETOH/IPA/xylene protocol. On the other hand I
processed some samples using a tert. butyl alcohol
schedule. There's hardly any difference between the
two regarding sectioning properties...

By the way: is there something as a "standard
thickness" for plantanatomical sections? 

Thanks in advance for every suggestion!

Yvan.

Hello, Histonetters
I am taking a census: what stain do you/your pathologists prefer to
demonstrate H. Pylori?
How many of you do IHC?
How many do special stains, and if so, which one?
I do a Steiner here, which is time consuming, even in the microwave,
and seems to give variable results in staining intensity, so I'd like
your opinion as to what stain you prefer.
Thank you,

We do Genta - actually a modified Genta. We have the Artisan - so we do a
Warthin Starry and add the rest off line. No IHC.

I am replying on behalf of my technologists to say that their
pathologist likes ipox, though usually does with an H & E.
He asks for it when there is an appearance which suggests H. pylori
should be there but can't see it, or when he sees organisms but they are
not typical shape. (H. pylori occasionally has a coccal form).

One of the girls did a project comparing 6 or 7 stains and the best was
ipox,as one would expect. The next best was Giema, in that it gave the
best staining against background light staining, most consistently.
Silver stains were pretty hopeless. Tol. Blue easily overstained, and
others were too laborious.

Hello, Histonetters
I am taking a census: what stain do you/your pathologists prefer to
demonstrate H. Pylori?
How many of you do IHC?
How many do special stains, and if so, which one?
I do a Steiner here, which is time consuming, even in the microwave, and
seems to give variable results in staining intensity, so I'd like your
opinion as to what stain you prefer.
Thank you,

Hi
 
I would like to purchase a microwave to use in our  ICC lab for antigen
retrieval, can anyone recommend a reliable laboratory microwave???( at
present we have a old household Sanyo model but would like to buy a new
one where we can accurately measure the internal temperature).
 
Thanks

Hello Delores and everyone else,

We use IHC for the demonstration of H pylori. I don't get caught up in the 
argument of IHC vs. special stains. If our doctors like IHC, that's fine 
with me. Job security says it all.
I use Dako's rabbit polyclonal antibody at 1:100, pretreat with Brigati's 
stable pepsin, and detect with a biotin/streptavidin system. I like AEC, 
but sometimes use DAB as the chromogen.

After taking a couple years off from Histonet.... I'm back

Hi Yvan,
The procedure we followed is listed below.  We had pretty good results as
far as sectioning went.  We are staining with safranin and fast green or
hematoxylin and safranin.  Neither comes out as bright as I would like to
see it.  I would welcome any suggestions you have for staining.

Processing Plant Tissues for Paraffin Sections
 
On January 5 and 6, 2007 various plant organs were collected in the SJU
Greenhouse.  They were fixed in FAA and kept in this solution until February
13 and 14, 2007.
 
The composition of  FAA is as follows:
         95% ethanol                            50 cc
         glacial acetic acid                    5 cc

Dehydration and clearing was carried out according to the following
schedule:
 
1.  Jar #1: 30:50:20 water:alcohol:tert-butyl-alcohol
 
2.  Jar #2: 15:50:35 water:alcohol:tert-butyl-alcohol for 1 hour.
 
3. Jar #3: 25:75 alcohol:tert-butyl-alcohol for 1 hour.
 
4.  Jar #4: 100% Tert-butyl-alcohol for 1 hour.
 
5.  Jar #5:  100% Tert-butyl-alcohol for 1 hour.
 
6.  Jar #6: 100% Tert-butyl-alcohol + paraffin chips, ON at 45oC.
 
7.  Jar #7: Pure paraffin 30 min, 60oC under vacuum
 
8.  Jar #8: Pure paraffin in 60oC oven 1hr.
 
9.  Jar #9: Third change of pure paraffin in 60oC oven 1hr.
 
10. Embed.

A current project is cutting slides to check for fluorescein expression.
The first time I did this, I was asked to air-dry the slides and mount
with aqueous medium; as you can expect, the coverage was "iffy" at best
with lifting of the coverslip, etc.  Is there any reason I could not dry
these in a 60 degree oven as usual, then deparaffinize and coverslip out
of xylene?  Would this process compromise the results? Help? Thanks!

It depends on the clinical history. Some GI bx's are accessioned and H 
pylori is prospectively ordered. Other IHC requests come in as a direct 
order from the attending pathologist or resident in training.

Sara,

Try it, but keep sections in the dark to avoid photobleaching.  Fluorescein 
should survive deparaffinization and then coverslipping.  Putting in an 
extra xylene to ensure good paraffin removal before putting a coverglass on 
may be of help.  We have some who do that here but they are requesting 
thick sections ~ 10 um or so.  I generally just air dry at RT in a dark 
place.  If you want to know the effects of temperature on FITC, contact 
Molecular Probes technical services, they will know about this also.

However, if the tissues are fixed with formalin, you may be battling 
autofluorescence.  At 08:48 AM 4/13/2007, you wrote:
