A drop of eosin, four drops of nigrosin and a small drop of semen are placed on a clean, grease free slide. Mix the semen first with eosin and then immediately with nigrosin stain. The mixture is taken on the edge of a slide and pulled across the top of another slide leaving a smear ( click here to view picture ).

The nigrosin component of the stain is used as a counterstain to ease visualization of the unstained live spermatozoa. This stain is also widely used to assess the morphologic characteristics of the spermatozoa. Preparations are made by depositing one drop of the supravital eosin-nigrosin stain on a prewarmed slide.

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. The glass of the slide will stain, but the bacterial cells will not.

Nigrosin is a simple and indirect stain used for determining bacterial morphology. The shapes and sizes of the organisms are seen as color-free outlines against the dark background. An advantage of using this method is that prior fixation by heat is not needed, so the organisms are seen in more lifelike shapes. The stain is a suspension of carbon, found in India ink or nigrosin. The carbon particles are negatively-charged, as is the cell membrane.
