Annette,
When we had our Ventana NexEs we antigen retrieved in a pressure
cooker....put two coplin jars with Cell Marque Trilogy in the cooker, place
your slides in one of them and leave in pressure cooker 10 minutes after it
reaches pressure.  Relieve the steam from the cooker, remove the lid and
place the slides in the other coplin jar of Trilogy for 10 minutes then
rinse in APK was and place on the machine, 32 minute antibody time, 
with amplification.

Hi Histonetters,

To clarify my question of the other day:  is it true that Masson's trichrome
could potentially stain fibronectin and/or smooth muscle actin, especially
if it is being overexpressed?  Is there a histochemical stain for
fibronectin?  We have already successfully done IHC,but are trying to
reconcile data obtained with a few different approaches.  We are mostly
working in lung.

Thanks to those who have already provided ideas!

Does anyone have an extra Fisher 166MP or 166A.  Mine is beyond repair and
would like to find a working unit.  Please email directly.   Hope the sales
reps do not call, the budget does not allow for new units at this time.

Dear Histonetters,

It's nice to be back with Histosearch after a short break. 

Well, I am facing problem with PCN staining of urinary bladder of rat. We 
are using Zymed PCNA staining kit for the same. I am getting non specific 
staining where even the nucleus of the muscle layers are also staining. We 
are retrieving the antigen by heating the sections in Citrate buffer. But 
we are not having this problem in the intestines of same control animals. 
Does anybody have experience of PCNA staining with U. bladder so that they 
can advise me about this problem. Ofcourse we have increased the blocking 
time with serum upto 30 minutes unsuccessfully.


Thanks in advance.

No modification is needed. Neither does it stain the Actinomyces. Rather,
the club shaped ends of the filaments, being an antigen-antibody complex -
known as Splendore-Hoeppli phenomenon - are stained red. They are not
necessarily present.

Be most grateful if anyone out there can recommend antibodies against those 
two proteins, that work in mouse pwx sections. I have got Chemicon's p75 ( 
MAB 390). The p75 is the low affinity neurotrophin receptor. I have searched

but I obviously am reluctant to buy unless confirmed that they work in pwax.

Thank you

(ITALY)

I would like to thank for your answers at my question about snail.
I also think to do something pleasant and to raise the scientific contents
of someone answers by sending them an Italian recipe on snails with garlic.
Sorry in Italy we use the olive oil. Butter is very dangerous for the heart,
the arteries ( just like the cigarettes smoke) and it also gets fat.
I am afraid but the recipe is in Italian.
But I'm sure if you enter a good Italian restaurant they can cook it.
But...remember... do not forget to bring with you the snails!

With my Best Regard

LUMACHE CON L'AGLIO (SNAILS WITH GARLIC)

INGREDIENTI PER 4 PERSONE

1Kg di lumache già spurgate (appena pulite vi consiglio di metterle per più
di 2 ore al sole in un contenitore con abbondante sale sui bordi, le lumache
infatti attirate dal sole e dal sale escono tutte fuori)
4 spicchi di aglio (GARLIC)
1 mazzetto di prezzemolo
olio extravergine di oliva (OLIVE OIL)
sale 
pepe

Lessate le lumache per 15 minuti, schiumando con un mestolo forato
("schiumarola" appunto).
A fine cottura, sciacquatele, rimettetele in tegame con acqua pulita
leggermente salata e cuocete per altri 15 minuti.
A questo punto, sgocciolatele (conservate però un po' d'acqua di cottura) e
trasferitele in una casseruola, dove avete fatto soffriggere per poco tempo
l'aglio, il prezzemolo e il pepe, cuocete per pochi minuti e aggiustate di
sale, irrorate con l'acqua di cottura e servite in una zuppiera con del
prezzemolo fresco.

E adesso inizia lo spasso....
buon appetito

We antigen retrieve our synaptophysin in Citrate Buffer  ph6.0 in a steamer.
We set the steamer with the citrate in it for 70 minutes, at 20 minutes left
we add the slides. After it steams for the final 20 minutes we let it cool
for 20 minutes. We add amplifier and blocker too. Is your primary dilution
correct?

Dear Phil (and others),

All this talk of ripping open snail shells, injecting with MgCl2 and 
heaven forbid, fixing alive! Does anyone else out there have to work 
within the constraints of an Animal Care Committee? 

Some of you might be interested to hear that in a an academic 
setting, all procedures carried out on research animals (be it 
crustacean, fish, avian or mammalian) have to be approved under 
guidelines for ethical and humane use and care of animals for 
research. For instance, while I have no objection to boiling my 
lobsters alive at home, at work, lobsters must me properly 
anesthetized prior to humane euthanasia! It's a strange world we 
work in by times!
Cheers!
Greg

For what it is worth, we were once sited by CLIA for lack of adequate
tracking documentation for sending blocks and slides outside of our
facility. We sent them via regular first class US mail and the block was
never received at the other facility. 

It is our understanding that there should be a written policy regarding how
these will be send, i.e. FedEx with tracking numbers etc., and how to follow
up to ensure that materials were received at the other facility and a
mechanism to ensure materials are returned.

Greg,

Yep, we've got an Animal Care Committee here at Univ. Wisconsin, and 
all the rest. They -- and most such entities in the US -- just don't 
care about anything that doesn't have a backbone.
Besides, MgCl2 and cooling *are* anesthesia for snails, as well as 
some crustiaceans at least (my own critters, if a I had a job doing 
critters, instead of running microscopes for biomedical types). 
MS-222 might work on aquatic snails, but not on land ones.
CO2/CO might work on Pulmonates, come to think of it (land snails are 
Pulmonates).
I have to agree with anesthetizing lobsters before dropping them in 
the boiling water, though -- I've never believed that they don't feel 
the boiling.

Hi Carrie:

    While Masson's might (or might not) stain fibronectin and actin, no 
one (ie. reviewers of your work) will believe that it is specific 
without rigorous testing. If the results with Masson's do not agree with 
IHC, I cannot believe that anyone would throw out the IHC result in 
favor of the Masson's result.

Annette,

We retrieve our Synaptophysin in a decloaker for 2" in either our home made
citrate buffer or Biocare's Bull's Eye and then stain on the NexES for 32".
Ours isn't real intense either.  Try decloaking for 3-4".  This should help.

I used to use soda water to temporarily put Gammarus,a small

twitching. I was told it was the CO2 that did it. Had to be careful 
not to overdo it and kill them, as I needed to recover them.

          As for lobster , I put them in the freezer for about 20 min or 
so til they hardly move , and then plunge them in boiling water 
head first. They supposedly die before waking up , so the theory 
goes. Makes me feel a little better and I don't lift the lid  :-).

               Lobster goes well with garlic and butter too,

Hello,

I would like to devise a quantitative graded scale for IHC results which
would provide more info than just +/- staining.
I have a reference where  IHC staining intensity was rated (from pale pink
to dark red) using alkaline phosphatase/Vector-Red, however we are using
Envision+/AEC which seems to be an all or nothing (red or no red) chromogen
with no gradation. We just received ImagePro image analysis software, so
this may be another route to try.  Thanks in advance for any comments or
suggestions you may have.

Gammarus! One of my favorite critters -- did a lot of work on them at 
Memorial in St. John's NF. I didn't try soda water, but, yes it 
should work fine, and I agree, the CO2 should be what does the job.
Lobster with garlic and butter ... mmm ... amazing how much lobster 
is left over to be "disposed of" when doing EM on the sinus gland.

Hi Carla,
I certainly may be corrected by others on this but I personally don't 
think you will obtain statistically valid data by grading intensity of the 
reaction between cells or fields or sections. There is just so much 
room for subjectivity and for that matter, variability between runs or 
perhaps even between slides within runs!

What you may want to try is calculating a ratio of positive to 
negative (perhaps pos. cells vs. neg. cells in a given area). For 
instance: place a grid with 50 or 100 intersects on the computer 
monitor, choose a microscopic field (in a random or systematic- 
random manner), and then at each intersect decide whether the 
reaction at that point is positive or negative. If at any particular 
intersect you have trouble to decide whether it is  pos or neg, have 
a system that does not permit subjectivity, such as: for such points 
where the call could go either way, look at the space imediately to 
the left of the y-axis and above the x-axis and then make your 
decision. Determination of the number of fields you need to sample 
in order to obtain statistically valid data is very important and a 
matter for a statistician to explain and/or determine for you (which I 
most definately am not) unless you happen to have that training 
yourself.

Another idea would be to have the image analysis software either 
measure the area of or count the number of pixels in a given area 
(field) that are "this red or redder". This involves choosing a 
relatively arbitrational threshold for the degree of redness that is to 
be measured or counted and applying the exact same setting to all 
other fields and sections in the study. My personal experience 
(using Bioquant NOVA) has been this sounds great in theory but 
was very difficult to pull off! The good old-fashioned counting was 
much more reliable and for that matter, easier to defend in 
presentation or publication. 

I am eager to hear other ideas or methods that might also work! 
Good luck.
Greg

Hi Carla,
I certainly may be corrected by others on this but I personally don't 
think you will obtain statistically valid data by grading intensity of the 
reaction between cells or fields or sections. There is just so much 
room for subjectivity and for that matter, variability between runs or 
perhaps even between slides within runs!

What you may want to try is calculating a ratio of positive to 
negative (perhaps pos. cells vs. neg. cells in a given area). For 
instance: place a grid with 50 or 100 intersects on the computer 
monitor, choose a microscopic field (in a random or systematic- 
random manner), and then at each intersect decide whether the 
reaction at that point is positive or negative. If at any particular 
intersect you have trouble to decide whether it is  pos or neg, have 
a system that does not permit subjectivity, such as: for such points 
where the call could go either way, look at the space imediately to 
the left of the y-axis and above the x-axis and then make your 
decision. Determination of the number of fields you need to sample 
in order to obtain statistically valid data is very important and a 
matter for a statistician to explain and/or determine for you (which I 
most definately am not) unless you happen to have that training 
yourself.

Another idea would be to have the image analysis software either 
measure the area of or count the number of pixels in a given area 
(field) that are "this red or redder". This involves choosing a 
relatively arbitrational threshold for the degree of redness that is to 
be measured or counted and applying the exact same setting to all 
other fields and sections in the study. My personal experience 
(using Bioquant NOVA) has been this sounds great in theory but 
was very difficult to pull off! The good old-fashioned counting was 
much more reliable and for that matter, easier to defend in 
presentation or publication. 

I am eager to hear other ideas or methods that might also work! 
Good luck.
Greg

Massimo, 
      I am sorry that you do not often have the pleasure of eating 
lobster. If you are ever in Prince Edward Island , Canada , then I 
will feed you lobster. You might find it an interesting comparison 
with the Mediterranean lobster which has a different flavour and 
texture.

       Thank you for the recipe for escargot; I love them and always 
wanted to know how to cook them. I sent the recipe to my 
daughter who plans on going to Italy next summer on an 
archaeological dig and she sent me back a rough translation, 
which you can find in the attachment.  

                                       Bon Appetit,
       
                                                      Margaret
