Depending on user requirements and personal preferences, it can be used for the preparation of the commonly used aqueous or alcoholic Eosin Y staining solutions. This staining solution will mostly be used for routine staining in the hematoxylin-eosin staining process (H&E). The H&E staining process is the most frequently used staining method for histological material. Due to the hematoxylin solution, the nuclei will appear blue to dark violet in color and the Eosin Y solution will stain the cytoplasma and intercellular substances red-orange.
As the Eosin Y dye belongs to the portfolio of Certistain® dyes, it is chemically analyzed according to strict specifications before release (CE marked and IVD product) and a high staining quality, with reliable staining results is guaranteed.产品信息 CAS号 17372-87-1 EC号 241-409-6 Hill配方 C₂₀H₆Br₄Na₂O₅ Molar Mass 691.86 g/mol HS代码 3204 12 00 结构配方图像 理化信息 熔点 295 - 296 °C pH值 9.2 (10 g/l, H₂O, 20 °C) 容积密度 710 kg/m³ 溶解度 300 g/l (20 °C) 毒性学信息 LD 50口服 LD50 Rat > 2000 mg/kg GHS安全信息 储存类别 10 - 13 其它液体及固体 WGK WGK 2 水危害 一次性 3
