[Histonet] RE: Glass vs Tape coverslippers

There is little question that if all things being equal, glass would be the preferred option for coverslipping. Some glass coverslippers today have addressed the main advantages that tape has had over glass, speed and wet slides. 

The Medite RCM7000 (Meisei Promounter) has the ability to coverslip at a rate of 450 slides/hr. It also has a slide drying fan that produces touch dry slides, eliminating the messy wet slide issue that has historically been associated with glass coverslipping.  

Anyone that has gone back to slides years after being coverslipped with tape would be familiar with the deteriorating nature of tape coverslipping over time.

I was demoing coverslippers and didn't tell the pathologists. Thought I'd see if they could tell the difference. One of our pathologists made us remove the tape from her entire days workload and recoverslip them by hand. Oh well.....

Gary, We did find that plastic was no good for cytology specimens - at least
the lumpy ones - it wouldn't form a flat surface. For thin-prep it worked
great. I think the quality is OK for routine histology. In our lab we did
testing in the lab and when satisfied it was working well we switched over
without telling the pathologists. About two weeks later the Chief
Pathologist asked me when we would start using the plastic coverslips!

Plastic is no substitute for glass.  Just because one doesn't "see" a
difference doesn't mean there isn't a difference.  Whether the difference
makes a real difference in outcomes is another story.

ASTM specs for cover glasses apply to glass, not to tape.  The higher the
numerical aperture of an objective, and the better the objective quality
(i.e., achromat, fluorite, apochromat -- plan and non-plan), the more likely
that one will see imaging differences when tape is used.  Of course, using
glass doesn't ensure good quality.

Practical stuff like mounting medium and cover glass thickness, clean
lenses, and Kohler illumination also play a real role.  Image quality can't
be better than the weakest link.

The specs are relative to the impact of the physical and optical properties
of glass on light as it passes through the mounting medium and glass through
the objective.  For this reason, it's not nice to fool Mother Nature and use
plastic.

We have a tape coverslipper, and we love it.  It is fast and we have had
very few problems with it.  Our pathologists have no problem reading the
slides, and as far as I know, there's never been a problem photographing a
slide.  We did demo the glass coverslippers when we were first looking for a
new coverslipper, and there were too many problems with slides sticking
together, air bubbles, and it was just all-around not as "user friendly."

Hello again,
 
I'm looking for opinions on the subject of glass coverslippers versus tape  
coverslipping.  I have the opportunity to decide on a system.  My only  
experience has been with tape coverslipping.  I understand machines  that
glass 
coverslip are slower than tape systems. Is the refractive index  better with
glass 
coverslips under the microscope?  Opinions pros/cons are  appreciated.

Thanks, Gail, you're right.  Does FA-11 work on FFPE tissue and do 
you need HIER?  Serotec doesn't say.

Thanks,
Sharon

   Pam and all,
   Too  many  people forget  or ignore the fact that some individuals who
   are  experts  in the field of histotechnology are not employed in just
   clinical  or research laboratories.  If one is involved with a company
   doing  technical  research  and  development of a product destined for
   histoland,    then  they  are  should  be  very  welcome  to  comment.
   Knowledge  should  not  be  smothered (flames!)   I don't see you as a
   salesperson,  but  a valuable resource providing me with information I
   can choose to use or not.  All part of the learning experience.
   Complaints = delete button.

I completely agree with Gayle! This list is invaluable to most of us

Especially the archives!  Quite often a topic is of no interest to me at the
present time yet a week later, I have to stain for that certain CD antibody
that I remember was discussed in detail the prior week.

I use the archives several times a week and if all responses were private,
there would be no archives!

Here is a puzzle.  In order to streamline the IHC workload, I have had the
techs organize the slides in vertical racks that can be used for dewaxing,
heat retrieval, and quenching (meth/px), instead of the old way of dewaxing
in one set of racks, switching to other racks for retrieval, and then into
coplin jars for quenching.  Sounds great.  We ended up with an unusual
vertical staining pattern with central staining of the tissues, but both
edges that corresponded with the edges of the slide racks had no staining.
The slides were heated at 60 deg. overnight.  Slides that did not require
heat retrieval were not affected, therefore it was not a dewaxing problem.
All slides lay flat for application of antibodies and detection system.  I
know of another site that vertically handles their slides, and they do not
get this artefact, the only difference between them and us is quenching
before retrieval vs after.  Any suggestions?  We went back to the old way,
and the artefact is gone, nothing changed except the position (vertical vs
horizontal) of the slides.  Looking forward to scientific explanations,
inquiring minds want to know.

Hi I have searched the archives and found a lot of discussion of BRDU, but 
no answer to the question if there is a protocol out there for 
formaldehyde-fixed, vibratome-cut, free floating sections.  Actually we 
could mount them on slides as well, I just don't want to do the whole 
paraffin embedding thing.
Also is it really necessary to have thin sections if you are going to use 
pepsin and acid, etc. ??

We could probably cut as thin as 20 um, but would prefer to use 40 or 60 um.

We will be doing this in pregnant ferrets (E36, gestation is ~42 days) and 
examining the brains at ages P0-P15.

Thanks very much for any help!!

Has anyone used the antibody to ID-2?  We purchased it from Santa Cruz 
Biotech.  They had some recommendations for western blot, but none for 
immunohistochemistry.
Our goal is simply to label the superficial layers of ferret visual 
cortex.  But on our first try using 1:50, 1:100, and 1:200 primary 
dilutions - it didn't work at all.
We were wondering if we need to do some antigen revealing step.  Or perhaps 
it will not be found this caudal?

Anyone know of any antibodies that label a specific layer in visual 
cortex?  I've heard that the otx1 antibody is not working well right 
now.  We are going to get RORbeta to attempt to stain layer IV, but again - 
no specific protocol for it.

Thanks very much for any help!

Amy,
	I have a new carousal waiting to be installed as we speak. I have 2 XT's,
the oldest one since February of this year. I've had 8 different heating
pads go bad on three different occasions since February. Most of the time,
we place our control on the same slide as the patient, so if the control
worked, there is no question that everything worked okay. If the control is
negative, then we repeat the slide on the newer machine.
	In all fairness to Vetnana, they have responded well to our phone calls and
emails. I think this is an issue that they are trying to work on in house.

Hi Kimberle,
   I've done quite a bit of vibratome sectioning and free floating
staining.  It's quite challenging!  Two ways I can think of that might
help you.  One would be to use the Shandon coverplate system.  The
sections would be floated onto slides and then the coverplate carefully
placed on to the slide.  It then fits into a holder and it gravity feeds
the reagents over the slide.  It uses a very small amount of reagent. 
The other way is to handle the free floating sections in netwells or you
can make your own using open cassettes and small petri dishes.  The most
important steps would be making sure the rinsing steps were sufficient. 
The netwell/petri dish method would use a much greater amount of
reagent.  Hope this helps.  Sarah

Is anyone looking for H. pylori control tissue?  We just had a partial

Baowei & All,

If you don't want to deal with large amounts of grief, I would encourage you
to respond privately.  Due to threats of calls to my employer, lawsuits,
profanity, constant flaming of every response I post and attaining my own
little histonet stalker (you know who you are), I keep 99% of all my
responses private.  There are a number of people & vendors on this
listserver that revel in tearing down the posts of others rather than
creating helpful or insightful posts themselves.  It is not a bad thing for
you to post privately to avoid these problems.

I actually used to post publicly up to the point that I was dealing with
personal attacks more than I was gleaning useful information from the
histonet.  Engaging in those types of interactions was too time consuming,
draining & enfuriating.  Expressing one's own view is nice and, yes, it
should be OK, but it isn't.  I see no value in "shaming" someone into
posting publicly.  If you don't want to...don't.

The funny thing is that I'll be getting flamed for this post which is
whining about being flamed...isn't it ironic?

Just My OPINION,

Dana,

There was heaps written about this on Histonet previously, look in the
archives.
We found that the problem was associated with the Plus slides when used in
conjunction with an EDTA buffer as the material used to coat the slides is a
calcium salt and the EDTA was affecting the coating by chelating the
calcium!!!

Hi Everyone!

I was recommended to try the Masson's Trichrome stainings on the slides of uterine tissue that I have been collecting (Previously I had only performed Hematoxylin & Eosin stains). This is a new method to our lab and thus far, staining has not gone well. Although my sections contain a significant amount of muscle, I have only been able to see the aniline blue stain. On a couple of the slides, there was a slight dark purple coloration on the epithelial lining. 

I have noticed upon comparing the protocol we received to others found on the internet that ours lacks the step in which  the slides are placed in Bouin's fluid. There was also no specification in our protocol for the type of hematoxylin, so we had been using the same hematoxylin (Harris's modified with acetic acid) that we use in our H & E stainings. I was wondering if any of these might have led to the stainings not going as planned. The tissue sections also looked slightly brittle, perhaps due to a harsher stain. I am wondering if this has anything to do with my fixation process in which I use a 4% paraformaldehyde/PBS mixture, ethanol and xylene steps, as well as embedding the tissues in paraffin. 

Is Bouin's a crucial step, would I have better staining with a different tissue fixation, or should I be looking in a different direction? Any suggestions would be very much appreciated!
Thanks!

I believe how the NSH Control bank works is that you let NSH control block
coordinator know what you are willing to share. You then hang onto the
blocks, and if anyone contacts NSH asking for a specific control, they
receive a list of the people willing to share. That person then calls
someone on the list, asks for the control, and the person with the control
sends it out.

Below is the NSH control bank person, if I remember correctly.

hello
Do you know which fixative can i use for intracellular immunostaining for FACS ?
We use saponine 0.1 % for permeabilisation.
Thank you for your help

I was wondering if there is(are) any immunohistochemical antibodies or
special stains besides Hale's Colloidal Iron for the differentiation of
Oncocytoma and Chromophobe in kidney?  I am not able to make the dialysised
(sp?) iron needed for the Hale's but would like to offer my pathologist an
alternate.  Any suggestions?

Amber,

Don't know where you got your protocol but I would suggest ANY of the standerd Histology books.  As for an answer to your problems.

1- mordent in either Boin's fluid or saturated picric acid for 60 min. at 60oC (there are other time, temp.'s and concentrations if one looks them up).  The method simply will not work without the modent.

2- use Weigert's Iron Hematoxylin as the nuclear stain.

Dear Histonet members,
staining of snap frozen muscle tissue for cytochrome oxidase (COX) using 
diaminobenzidine (DAB) works nicely in our laboratory.
We would be happy to know, however,  if anybody is aware of an 
non-carcinogenic alternative method to visualize cytochrome oxidase 
activity.
Thank you very much for your help

Amber,

Below is a modified version of the original Masson's Trichrome which I
have successfully used for over 40 years.  Instead of using
Woodstain-Scarlet, which I don't think is available anymore, substitute
Crocein Scarlet which Sigma sells. 

Masson's Trichrome (Modified)    

Post-fix in Bouin's fixative overnight if primary fixation was not done
using Bouin's

1. Bring sections to water and wash for 5 - 10 minutes.
2. Stain nuclei for 15 minutes in Weigert's iron hematoxylin
3. Wash for 5 - 10 minutes in running water and rinse in 1% acetic acid.
4. Place slides in Woodstain Scarlet-Acid Fuchsin mixture for 5 minutes.
5. Rinse briefly in 1% acetic acid and differentiate in 5%
phosphomolybdic acid.  Differentiate to the point where collagen and
ground substances are pale pink to colorless, usually about 30 seconds
to 2 minutes. 6. Rinse in 1% acetic acid. 7. Place for 15 - 20 seconds
in the Aniline Blue solution (Aniline Blue - Woodstain Scarlet - Acid
Fuchsin mixture). 8. Place for a quick rinse in 1% acetic acid. 9.
Dehydrate in four changes of alcohol. 10. Clear in xylene and mount in
permount.

Preparation of Staining Solutions:

Weigert's Hematoxylin:
Solution A:
29% ferric chloride - 4 ml
Distilled water     - 95 ml
Conc. HCl           - 1 ml
Solution B:
Hematoxylin - 1 gm
95% ethanol - 100 ml
For use, mix equal parts of solutions A and B.  Use fresh each time

Woodstain Scarlet-Acid Fuchsin:  prepare a 1% solution of Woodstain
Scarlet NS and a 1% solution of Acid Fuchsin (C.I. no 692).  Mix 8 parts
of Woodstain Scarlet solution with 2 parts of Acid Fuchsin solution and
add 1ml acetic acid to 99ml of the mixed dye solution.  

Aniline blue:  To 85ml of 1% acetic acid add 5ml of a saturated solution
of Aniline Blue (C.I. no 707) and 10ml of the above Woodstain
Scarlet-Acid Fuchsin mixture.
