Enjoy strict quality control of raw materials and finished product and a high quality product every time with the Epredia™ Eosin-Y Alcoholic, Eosin-Y with Phloxine, and Eosin-Y Saturated Staining Solutions.
- Strict quality control of raw materials and finished product ensures a high quality product every time
- Eosin-Y Alcoholic produces three distinct color variations enhancing differentiation between muscle, red blood cells, and connective tissue
- Eosin-Y w/Phloxine yields a brighter reddish hue and a more dramatic differentiation of cytoplasmic color than Eosin-Y Alcoholic
- Eosin-Y Saturated is a very intense and rapid counterstain that can be used to make working solutions of Eosin-Y
Epredia™ Eosin-Y Alcoholic is an alcoholic, acidified counterstain. This product will stain cytoplasmic components three distinct color hues. Muscle, red blood cells and connective tissue all stain various shades of red and pink. Epredia™ Eosin-Y Alcoholic will provide a clear contrast between the cytoplasm and nuclei of the cell. No dilution is necessary for this product as it is ready for use. The pH of this Eosin product is between 4.8 and 5.2. Typical staining times are 30-90 seconds.
Epredia™ Eosin-Y w/ Phloxine is an alcoholic, acidified counterstain. Phloxine B has been added to brighten the cytoplasmic stain and give a more intense red color to the connective tissue, especially muscle. Inclusion bodies are better demonstrated by the inclusion of phloxine-B. Some pathologists prefer the look and range of cytoplasmic colors it provides. No dilution is necessary and it is ready for use. (see Cat. No. 84000-102, 84000-104)
Epredia™ Eosin-Y Saturated is an alcohol based, rapid cytoplasmic stain. It does not contain glacial acetic acid, so its pH is much higher (neutral) than other eosin-y alcoholic counterstains. This stain will provide intensities similar to other commercially available eosin-y products. Thermo Scientific Eosin-Y Saturated can be used as is or diluted for use. If the product is diluted, it is recommended to dilute with 70% alcohol to the desired strength. (see Cat. No. 84000-106)
