| Purpose |
It is used to stain the transparent and unstained capsules of microorganisms using the negative staining method. |
| Working Principle
|
The negative staining method allows the visualization of the usually transparent and non-staining capsules of many organisms, most notably Cryptococcus neoformans. Nigrosin consists of a suspension of fine carbon particles. These form a dark background against which the capsules are clearly visible as a result of the displacement of the carbon particles. |
| Warnings, Precautions, Recommendations
|
May cause sensitization by skin contact. Wear protective gloves/protective clothing/eye protection/face protection. |
