EA-36, -50, -65 and Modified EA are ready-to-use cytoplasmic counterstains used for gynecological and non-gynecological cytology specimens. These products contain common dyes and reagent solvents used in traditional EA formulations. A well-preserved or fixed slide with adequate exposure to 95% alcohol or a commercial spray fixative is highly recommended for optimal staining results. Cellular results are traditional as well, with basal or intermediate cells staining a blue-green hue and surface cells staining a pink-red hue. This multicolored effect is due to dye uptake by various cells and their affinities for the specific dyes.EA 50 is used in conjunction with OG-6 for the staining of gynecological specimens. It will provide a very traditional staining result with common staining hues and intensities. EA-50 can also be used for non-gynecological specimens however, although EA-65 is recommended.
A single chemical agent, dye or solution intended for the artificial colouration of specific target tissue structures, intra/extracellular elements and/or infectious microorganisms, in a clinical specimen, for their subsequent visualization, examination, identification and/or differentiation.
