Does anyone use agar in a procedure to prepare cell blocks from cytology material? I am interested in such a procedure as a method to help eliminate/reduce "floaters" in cell block preparations?

That is how I do VK, I put it in the window for 20 min or so. I do a
special H&E counterstain on mine, using an aqueous eosin. The eosin will
light up the osteoid by fluorescing under uv light. We use this with a
image analysis system to measure total area, calcified bone area (light
scope, from the black silver stain) osteoid seam thickness (fluorescent
scope using the eosin fluorescent property, everything else will be dark
except the osteoid seams) if you labeled the bone with a fluorchrome you can
just look at an unstained section to measure area between two labels.

James,
Try this: once the sections are brought to water, 5% silver nitrate in
either bright sunlight or a 60-100 watt incandescent light bulb for 30 min
(check for browning of the control tissue adjust time as needed). Rinse well
in distilled water. 5% Sodium Thiosulfate for 1 min. Rinse and counterstain
with nuclear fast red or whatever you think would look cool :-). Dehydrate,
clear and coverslip the slides.
Of course, as with any silver stain use acid cleaned glassware and gloves
unless you like watching your fingers turn black in the sunlight. Really
well decalcified tissue usually has the Calcium washed out. Try a calcified
breast or something that wasn't decalcified. This causes microtomists to
curse a lot, but it makes great VonKossa controls.
Have fun,
Amos

Hello everyone,
Does anyone have a good Von Kossa stain protocol that they would not mind
sharing, on animal bone tissue (femur/tibia) that has been embedded in GMA
or MMA (sections are between 5 and 10 ?m thick)? I would appreciate it
greatly. Thank you much.

Hi!
Can someone tell me the right pH for eosin y 1% aqueous solution?
The one I made from powder has pH 6.3. Is this OK? The commercial one we
usually buy is a bit lower (5.7).

Hello,
I have been using Gomori`s Aldehyde Fuchsin to stain human skin for
elastin. The stain works fine and is clear and specific. I am using
light green as a counterstain. My problem is that once stained, the
slides have an excess granular purple "dotted" appearance upon the
entire surface of the slide. This is not limited to the tissue position
upon the slide, but across the clear glass too. We have tried using both
superfrost plus charged slides and uncharged slides but the problem
still is present. This precipitate is spoiling an otherwise great stain.
Does anyone have any idea about what this is and how it could be
prevented? (Our next guess would be to re-filter the fuchsin solution
prior to use every time)
Many thanks

no - thats the really cool thing - think about it...
its that part of the bone which is usually quite hard but softens with
stewing/cooking and could be bitten off and chewed (if desired)
no demineralisation has taken place yet it is soft enough to slice with a
blade and once processed it cuts like butter on the microtome
i also have an amazing source of GMS control for fungus - an old mildewed
orange!!!
same process applies - slice off a piece, process and embed - stains on PAS
and GMS!!!
quite stunning
a pal of mine says that fish liver makes and amazing Oil red 'O' QC but have
not yet tried that one
i also hunt for liver QC material here in a country which does not do
autopsies - we trot off to the local butcher with a small jar of formalin
and pop a small slice of fresh beef liver into the formalin - am sure that
other liver would work just as wekk
some may argue that it is animal tissue but in my opinion it it not the
tissue but the glycogen we need to demo - so its not an issue - my Paths are
happy so im happy

The eosin should be acidic and you get to that point adding 1% aq. sol. of acetic acid to you prepared solution, at a rate of 1 mL acetic/100 mL of eosin solution.

If you are having a hard time with a pathologist regarding the use of B5,
get your safety people involved. They will take care of it. We stopped
using B5 a very long time ago. We use formalin for all our lymph nodes and
bone marrows. No one should be using B5 and manufacturers should stop

How many still use B5 fixative? And for those who do not, what do you use as
a replacement? One of our pathologists is insistent on using B5, and we'd

Hi all,
I have a problem and think I have figured out a solution to it but
need some expert advise.
I'm using biotinylated GS isolectin to stain frozen brain sections for
microglia. The GS isolectin is working very well but the
avadin-fluourophore is binding to the endogenous biotin in the tissue
causing a lot of back ground. I'm thinking of fist blocking the
sections by incubating it with unlabled avidin and then following it
with another blocking step with unlabled biotin so that all the
endogenous biotin is bound to avidin and the un-endogenous biotin
bound sites of the avidin are then bound to unlabled biotin. This
would then be followed by the GS Isolectin incubation etc...
Can anyone suggest a reasonable starting concentration for the first
biotin and avidin blocking steps? Do you think this will work at all?
Kind regards

Why not use an avidin-biotin blocking kit (like those from Vector or Dako for example). They work well, are optiimized already and aren't that expensive.

Subject: [Histonet] getting rid of biotin-avidin background
Hi all,
I have a problem and think I have figured out a solution to it but
need some expert advise.
I'm using biotinylated GS isolectin to stain frozen brain sections for
microglia. The GS isolectin is working very well but the
avadin-fluourophore is binding to the endogenous biotin in the tissue
causing a lot of back ground. I'm thinking of fist blocking the
sections by incubating it with unlabled avidin and then following it
with another blocking step with unlabled biotin so that all the
endogenous biotin is bound to avidin and the un-endogenous biotin
bound sites of the avidin are then bound to unlabled biotin. This
would then be followed by the GS Isolectin incubation etc...
Can anyone suggest a reasonable starting concentration for the first
biotin and avidin blocking steps? Do you think this will work at all?
Kind regards

You shouldn't use secret mixtures, but Mollifex
isn't (or isn't quite) a secret formulation. BDH
made it following a publication by J. R. Baker
(1941) A fluid for softening tissues embedded in
paraffin wax. Quart. J. Microsc. Sci. 61:75.
Bakers experiments led him to the composition:
Glycerol 10
60% ethyl alcohol: 90
(parts by volume).
A more recent paper is by Maria Wynnchuk (1992)
in J. Histotechnol. 15(4): 321-323. She used
a mixture called Horne's modification of Baker's
solution:
95% ethanol 9520 ml
Glycerol 320 ml
Acetone 80 ml
Liquid phenol 80 ml
(I guess that the "liquid phenol" is an 80%
solution in water, not solid phenol that has
been melted by heating.) 10 litres of softening
solution seems a lot to make up! I wonder
how long it lasts for.
Wynnchuk states that this mixture is better
than Baker's original and that Mollifex, which
contains a "phenol derivative" is just as good.
Anything here for Messrs Sue, Grabbit and Runne?

Fisher, which is exactly what we need but they break very easily.
What we like about these is
-when the time runs out and the alarm beeps for one minute the sound stops
but the timer continues to count up until you stop it
-you DON'T enter the time by pushing the buttons a certain number of times
(ie, push minute button 30 times for 30 minutes)
-they run on one AAA battery
-the time display is pretty big
-they have a magnet on the back

B5, Schaudinn's, SUSA, Helly's, and Zenker's fixatives contain mercury (II) ions, which are VERY poisonous. Sewage bacteria convert mercury (II) to methyl mercury, which is very, very poisonous. (For a shocking example of mercury toxicity, see the photo essay MINAMATA by W. Eugene Smith.) When these fixatives are used, the fixative and the first washing must be given to a waste disposal company that can recycle it.
B5 substitutes substitute a less poisonous ion, usually zinc (II), for mercury. These substitutes contain other things that are more poisonous than zinc. I store them as if they were purely the most poisonous component and give them to a waste disposal company twice a year.

If you are having a hard time with a pathologist regarding the use of B5,
get your safety people involved. They will take care of it. We stopped
using B5 a very long time ago. We use formalin for all our lymph nodes and
bone marrows. No one should be using B5 and manufacturers should stop

How many still use B5 fixative? And for those who do not, what do you use as
a replacement? One of our pathologists is insistent on using B5, and we'd
