Description

Eosin Y Certified CAS: 17372-87-1 | MF: C20H6Br4Na2O5 | MW: 691.85, Buy now for reliable and reproducible results from Tristains.

Eosin Y Certified (CAS No. 17372-87-1) is a reddish-orange, water-soluble dye, that has a characteristic reddish-brown color. It is a certified dye derived chemically by Eosin B, with a molecular formula C20H6Br4Na2O5, and also goes by other names like Acid Red 87, Bromofluorescein, Eosin Yellowish and Solvent Red 43. Eosin Y Certified is commonly used in Hematoxylin and Eosin (H&E) staining protocols as a counterstain. The certified grade is a standardized, high-purity composition that can be used reliably in histology, cytology, biology, and other scientific applications.

Applications

  • Approved Counterstain in Histological Procedures: Eosin Y Certified is widely used as counterstain in H&E staining, in which it can be applied to amplify cellular and tissue structure by giving it high contrast.
  • Counterstain in Standard Staining Techniques: Often used in combination with hematoxylin, Eosin Y Certified is a stain of cytoplasmic components and extracellular structures, which enhances microscopic differentiation.
  • Use in Cytology: Eosin Y Certified is used as a nonspecific stain in cytology and cell biology to help in protein metabolism research and outline key components of the cell to examine morphologically.

Key features

  • Certified Quality Assurance: Produced under rigorous quality control standards and tested to be pure, guaranteeing reliable performance in laboratory staining use.
  • Accuracy in Microscopic Tissue Analysis: Facilitates proper cyto-biological and histological analysis of tissue sections.
  • Multi-purpose Staining: It has good staining characteristics making it compatible with many histology and microscopy methods.

General Description

Eosin Y Certified (CAS No. 17372-87-1) is a certified histological stain and cytological dye that has been characterized by the color of reddish-orange and a molecular structure of C20H6Br4Na2O5. It is also known as Bromofluorescein, Eosin Yellowish and Acid Red 87. Certification denotes that the dye is of known standard compositions, consistency and functionality to be utilized in purpose of research as well as diagnostic use. Eosin Y Certified is a derivative of Eosin B and it is mainly used as a counterstain in the Hematoxylin and Eosin (H&E) staining, which is one of the most widespread staining procedures in microscopy and histopathology.

Eosin Y Certified can be used in analytical biology, histology, microbiology, and cytology methods because of its chemical properties of protection and stability of stain. TriStains also offers certified histological dyes and stains that are supposed to perform to laboratory standards. The price on Eosin Y Certified varies according to the size of the package and the quantity ordered. There is a variety of packages and a discount on buying in large quantities. To obtain the pricing and ordering details, contact the authorized sales team or refer to the official product listings.

TECHNICAL INFORMATION
Alternate Names 2′,4′,5′,7′-Tetrabromofluorescein; Acid Red 87
Application Eosin Y sodium salt is a red fluorescent dye from the xanthene family
CAS Number 17372-87-1
Molecular Weight 691.85
Molecular Formula: C20H6Br4O5•2Na

For Research Use Only. Not Intended for Diagnostic or Therapeutic Use.
* Refer to Certificate of Analysis for lot specific data (including water content).

Eosin Y, a red xanthene dye, has been noted to reduce the affinity of Mg2+-ATPase for ATP and increase the enzyme affinity for Mg2+ at concentrations of 10-50 μM. At higher concentrations near 100 μM the affinity for Mg2+-ATPase for the ion-activator has been shown to be reduced. This compound has also been reported to be a photosensitizer that works as a molecular photoelectrode via catalyzation of the visible-light-driven electron-transfer reaction. Eosin Y has been used to stain structures such as muscle, cytoplasm, and collagen. This agent also enhances fluorescent quenching abilities by forming a complex with polyvinulpyrrolidone.
