Aoyama’s Fluid
Formula
Material | Amount | |
---|---|---|
Cadmium chloride | 10 | g |
Strong formalin | 150 | mL |
Distilled water | 850 | mL |
Description
The formula specifies that the strong formalin should be neutralized. Using a freshly purchased solution may avoid this, but if it does not, neutralize by layering the strong formalin over calcium carbonate (marble chips or crushed oyster shells) overnight in a loosely covered container under a fume hood.
This fixative is useful for the Golgi apparatus and general morphology. Average-sized pieces should be fixed within 4 to 12 hours. There is no special after-treatment.
Safety Note
Prior to handling any chemical, consult the Safety Data Sheet (SDS) for proper handling and safety precautions.
