BI LE - HALL'S BI LI RUBI N STAI N
PURPOSE: Bilirubin is the principal bile pigment, and is a normal product
of red cell degradation. Excessive amounts of bile pigment in the liver may
be found in cases of hepatic or extrahepatic biliary obstruction.
PRI NCI PLE: The oxidizing action of Fouchet's reagent converts the bile
pigment to green biliverdin (if it has been transported to the liver and
reduced, it is referred to as bilirubin.). Colors range from olive green to
emerald green, depending on the concentration of bile pigment present.
CONTROL: Tissue with a known positive control, an obstructed bile duct.
Coverslip slide with Permount, the fast drying media leeches out the
staining reaction.
FI XATI VE: 10% formalin
TECHNI QUE: Cut paraffin sections 4m.
EQUI PMENT: Balance, weigh boats, acid cleaned glassware.
REAGENTS:
10% Ferri c Chl ori de:
Ferric chloride 0.5 gm
Dist illed wat er 5.0 ml
Make FRESH.
CAUTI ON: Avoi d contact and i nhal ati on.
Van Gi eson's Sol uti on:
1% Acid fuchsin 1.0 ml
Picric acid, saturated 45.0 ml
Mix well, stable for 2 WEEKS.
CAUTI ON: Avoi d contact and i nhal ati on.
Fouchet's Reagent:
Trichloracetic acid 12.5 gm
Dist illed wat er 50.0 ml
Mix well, then add:
10% ferric chloride 5.0 ml
Make FRESH discard after use.
CAUTI ON: Corrosi ve, avoi d contact and
i nhal ati on. Can cause burns.

SAFETY: Wear gloves, goggles and lab coat. Avoid contact and inhalation.
Ferric chloride; causes GI distress when ingested. Solution reacts with
metal.
Trichloracetic acid; Corrosive to skin, can cause burns. Can cause damage
to the respiratory system on inhalation.
Picric acid; Toxic by skin exposure. Can become explosive when dry.
PROCEDURE:
1. Deparaffinize and hydrate to distilled water.
2. Fouchet's reagent, 5 minutes.
3. Rinse in tap water, followed by distilled water.
4. Van Gieson's solution, 3-5 minutes.
5. Rinse in dist illed.
6. Dehydrate, clear, and mount in PERMOUNT, or the coverslipper.
RESULTS:
Bile pigment: green
Muscle and cell cytoplasm: yellow
Collagen: red
