Eosin Y 0.5%, Buy Histological Stains solutions for Histology, Cytology, Microbiology, Hematology Biology Lab from TriStains at Dawnscientific.
Eosin Y, or Eosin Yellowish, or Acid Red 87, is a synthetic dye which belongs to the xanthene class. Eosin Y is usually dissolved in water or some alcohol to obtain a 0.5% solution. This lower concentration is typically used in histology and cytology to improve the contrast of certain cellular components, especially when combined with other stains like hematoxylin.
Applications of Eosin Y 0.5%
Key Features of Eosin Y 0.5%
General Description
Eosin Y 0.5% is a highly recognized histological stain and a xanthene type. It is used predominantly in Hematoxylin and Eosin (H&E) staining protocols in biological microscopy. This self-marking stain increases contrast in cells and tissues imaging, making it more beneficial for applications in the cell, tissue and biological science.
A synthetic water-soluble dye, Eosin Y 0.5%, is used as a prominent counterstain in cytological and histological staining. This product is rather brilliant pink in color and increases the contrast when cellular components are used with various dyes like hematoxylin that are used in microscopy.
Eosin Y 0.5% has been specifically designed for advanced histopathology laboratories and biological research labs. It is quite pink to red in coloration, which provides optimal visibility for cellular components when used in combination with other dyes.
Eosin Y 0.5% can be purchased directly from Dawn Scientific, which sells the product through its trusted brand TriStains. These divisions offer a wide range of histological stains and dyes for use in histology, cytology, microbiology, hematology, and cell biology.

TriStains Eosin Y 0.5% is primarily used as a counterstain in Hematoxylin & Eosin (H&E) staining, helping visualize cytoplasm, connective tissue, and extracellular matrix in histology and cytology samples.
It is supplied as a 0.5% (w/v) Eosin Y solution, a standard working concentration widely used for routine histological staining and microscopy.
Eosin Y (also known as Acid Red 87) is a xanthene-based synthetic dye derived from fluorescein, commonly used for staining cellular proteins and cytoplasmic components.
It is widely used in:
Eosin Y produces pink to red coloration, which provides strong contrast against hematoxylin-stained nuclei (blue/purple), enhancing cellular detail visibility under a microscope.
It delivers bright, uniform, and high-contrast staining, ensuring consistent differentiation of cytoplasmic structures and excellent reproducibility across staining batches.
TriStains Eosin Y 0.5% is typically an aqueous-based staining solution containing:
This ensures optimal tissue penetration and staining consistency.
TriStains Eosin Y 0.5% is commonly available in:
Larger bulk packaging may also be available for institutional and diagnostic laboratories.
Yes, it is specifically designed for routine histology and diagnostic laboratory use, especially in high-throughput H&E staining systems where consistent staining quality is required.
Because it provides an optimal balance of intensity and contrast, allowing clear differentiation of:
This makes tissue morphology easier to interpret in diagnostic microscopy.
