Negative Stain Test Nigrosin Stain Smear

What is this test?

The negative stain is particularly useful for determining cell size and arrangement. Nigrosin is an acidic stain. This means that the stain readily gives up a hydrogen ion and becomes negatively charged. Since the surface of most bacterial cells is negatively charged, the cell surface repels the stain.

Test Preparation

No special preparation is needed for Negative Stain Test Nigrosin Stain Smear. Inform your doctor if you are on any medications or have any underlying medical conditions or allergies before undergoing Negative Stain Test Nigrosin Stain Smear. Your doctor depending on your condition will give specific instructions.
