Re: [Histonet] PAS-diastase staining

2015-05-31 Thread Linda Prasad (SCHN)
We have been making our own diastase solution for years now. Works extremely 
well. The diastase is very easy to make in house. Here is the protocol for 
making your own diastase

Principle:  
The enzyme solution is applied to one of two sections of the tissue (preferably 
consecutive sections) and then both are stained by the PAS method.  The 
presence and relative amount of glycogen in the sections can be determined by 
examining the extent of loss of staining in the enzyme treated section as 
compared with the untreated section.

This amylase reagent has a long shelf life and uses an incubation time of 10 
minutes at room temperature. It is suitable for formalin and Brazil’s fixed 
paraffin sections as well as air-dried and ethanol fixed frozen sections.

Controls:   Liver containing glycogen

Reagents:   
1.  Amylase Reagent
Warning: Harmful, contains azide – see MSDS
Alpha Amylase from Bacillus Subtilis (Sigma Cat No 10070,)  1g
Oxoid PBS Tablets (Cat No BR14a)1 tablet
Distilled water 100ml
Sodium Azide0.1g
This solution, once prepared is stored at 4oC when not in use. A recycled 
antibody dropper bottle (often used in commercial immunoperoxidase kits) is 
useful for storage and application.

2.  PAS Reagents (see PAS Stain)
Warning: Suspected Carcinogen – see MSDS
 

Procedure:

1.  Dewax and hydrate paraffin sections, hydrate frozen sections.
2.  For amylase digestion, place slides on a rack, cover sections with 
amylase solution and allow to incubate for 10 minutes at room temperature.
3.  Wash slides well in water.
4.  Place slides in 1% periodic acid 10 minutes.
5.  Wash slides well in water.
6.  Rinse slides in distilled water.
7.  Place in Schiff’s reagent 10 minutes.
8.  Rinse slides in distilled water and then wash slides in tap water 3 
minutes.
9.  Counterstain slides with haematoxylin, differentiate and blue.
10. Dehydrate, clear and mount.

Results: 
•   Glycogen is extracted and so loss of PAS positive staining will occur 
in the enzyme treated section.

•   Mucopolysaccharides are not extracted and so staining will be the same 
in both sections.

Re: [Histonet] Plasma/thrombin clot for cell block

2015-05-06 Thread Linda Prasad (SCHN)
Hi Cheryl

This is the technique we use.

Thromboplastin Cell Block method

Principle:

The Thromboplastin cell block is very gentle on cells and allows a wide range 
of routine immunohistochemical stains to be done.
Plasma, treated with EDTA, is mixed with the specimen in the presence of 
thromboplastin and calcium ions to form a cell clot.
This method is not suitable for cells fixed in formalin or specimens of bile 
fluid (bile enzymes prevent clot formation)

Solutions:

1.  Normal Plasma, containing EDTA , use out of date plasma obtained from 
Blood Bank. Freeze in 2ml aliquots. This plasma has been tested for known 
viruses and is considered safe.

2.  Thromboplastin, use out of date thromboplastin obtained from 
Haematology.

3.  1% calcium chloride

4.  10% formalin

Method:

1.  Spin fluid using a centrifuge.
2.  Decant off supernatant
3.  Resuspend pellet in 3 drops of plasma.
4.  Add 3 drops of thromboplastin, mix
5.  Add 3 drops of Calcium Chloride, mix gently
6.  Allow to stand undisturbed for 15-20 minutes
7.  Add 5-8ml 10% formalin and allow to fix
8.  Place in a labelled tissue cassette and process as usual.

RE: [Histonet] Bouin's, formic acid & and sirius red staining

2015-04-15 Thread Linda Prasad (SCHN)
Hi Tryrone
A Mass Trichrome stain will stain up the collagen in the diseased kidney. If 
the tissue has already been fixed in Bouin's Solution you can omit the picric 
acid step. Another good stain is the Curtis's Van Gieson Stain. Ive sent you 
the protocol for botht he stains. Hope it helps.   

Masson Trichrome

Principal
This method depends on the special action of phosphomolybdic acid when combined 
with red aniline dye. The acid lifts the colour first from the collagen and 
only later from the cytoplasm. The differentiation is stopped at the point 
where the Collagen only is colourless, and then another aniline dye (light 
green) is added to stain the collagen

Reagents:   

1.  Ponceau Acid Fuchsin 
Warning: Suspected Carcinogen – see MSDS
Acid fuchsin (Sigma Aldrich CI 42685) 0.1g
Ponceau de xylidene (CI 16150)  1g  
Distilled Water 99ml
When dissolved, add 1ml Glacial Acetic Acid

2.  Light Green
Warning: Suspected Carcinogen – see MSDS
Light green (CI 42095)  2g  
Glacial Acetic acid   2ml
Distilled water 98ml

3.  Weigert's Iron Haematoxylin or Celestine Blue/Haematoxylin

4.  1% Phosphomolybdic Acid
Phosphomolybdic acid5g
Distilled water 500ml
 

Procedure:  

1.  Bring sections to distilled water.  
2.  Celestine blue  10 minute.
3.  Wash well in water.
4.  Harris' haematoxylin10 minutes.
5.  Differentiate and blue  
6.  Ponceau acid fuchsin solution   10min
7.  Quick rinse in tap water
8.  1% Phosphomolybdic acid 5min
9.  Do not rinse in water
10. Light green solution2min 
11. Rinse excess stain rapidly in water.
12. Dehydrate, clear & mount

Results:  
Collagen, mucin green
Muscle, Fibrin  red
Nuclei  purple

Curtis's Van Gieson Stain

Principle:
This solution is based on the same formula as Van Gieson with the exception of 
the use of Ponceau S rather than acid fuschin. Glacial Acetic Acid is used 
rather than hydrochloric acid to sharpen the staining results.

Reagents: 

1.  1% aqueous Ponceau S 
Ponceau S (CI 27195)0.5g
Distilled water 50ml

2.  Curtis’s Van Gieson
1% aqueous Ponceau S10ml
Saturated aqueous picric acid   90ml
Glacial Acetic Acid 1.5ml

3.   Celestine Blue – Haematoxylin procedure

Procedure:
1.  Dewax and hydrate sections.
2.  Celestine blue 5 minute wash.
3.  Wash well in water.
4.  Harris' haematoxylin 5 minutes.
5.  Wash in water and blue (do not differentiate).
6.  Curtis Van Gieson stain 10 minutes (do not wash).
7.  Rinse in absolute alcohol 
8.  Dehydrate, clear and mount.

Hello,

Some questions regarding Bouin's solution.

I was told, back when I was doing my PhD and new very little, that I should fix 
my fish in Bouin's as it will decalsify the bones. Well, Bouin's fixed fish 
were easier to cut than PFA fixed fish... but I read today that by adding 
formic acid the decalsification is better. (I must confess, that after Buoin's 
fixation I still had to soak the tissue face in some dilute nitric acid now and 
then...) Another reference said that the formaldehyde should be replaced with 
formic acid. So which is it: add formic acid or replace formaldehyde? And if 
the former, how much do you add?

Second question: a colleague and I want to stain for collagen in diseased 
kidneys. The fixative of choice for soft tissue is Bouin's... But the staining 
protocol called for a solution of picric acid and sirius red. Is the picric 
acid needed if I haven't washed the picric acid from the Bouin's fixation out 
of the tissue? I was told once that the picric acid was for contrast... Is

The mast cells are meant to turn purple. It’s a metachromatic stain. So the tol 
blue stains the tissue blue and the mast cells purple.

Mast cell granules  Purple
Acid Mucosubstance  Purple
Nuclei  Blue

Mast cells are rich in heparin. This allows them to be stained via acid 
mucopolysaccharide and metachromatic staining techniques. Churukian and Schenk 
developed this metachromatic dye-technique to reduce the excessive background 
staining that is common with metachromatic dye techniques.

I used strawberries for a fungal control. Worked really good.

How about mushrooms?  Has anyone had any success using mushrooms as a GMS 
fungus control?

Usually we do the DiPAS stain on muscle frozen section. Air dried for 10 
minutes. Don't use any fixatives :)

Greetings,


I am looking for fixatives that others are using in their labs 
for the PASD stain on fresh frozen muscle tissue. Currently we are fixing in 
10% NBF. Thanks in advance for any info on this.
