Pap Stain Kit

Principle of Pap Stain

The principle of pap stain is to clearly distinguish between basophilic and acidophilic cell components and obtain a detailed chromatin pattern. The HealthSky Papanicolaou Stain Kit consists of the Hematoxylin Stain and the EA/OG Stain. Hematoxylin dyes attach to sulfate groups on the DNA, stains the nucleus. Eosin (referred to as EA) and Orange G (referred to as OG) are cytoplasmic stains, the combination of EA/OG give the subtle range of green, blue, and pink hues to the cell cytoplasm.
