Eosin is the name of several fluorescent acidic compounds which bind to and form salts with basic, or eosinophilic, compounds like proteins containing amino acid residues such as arginine and lysine, and stains them dark red or pink as a result of the actions of bromine on eosin.

2024年4月26日 · Eosinophils are white blood cells that play an essential role in the immune system, specifically in fighting diseases and infections. A high eosinophil level, for example, can indicate a range of...

苏木精 — 伊红染色法 ( hematoxylin-eosin staining ) ，简称HE染色法 ，石蜡切片技术里常用的染色法之一 。 苏木精染液为碱性 ，主要使细胞核内的染色质与胞质内的核酸着紫蓝色 ；伊红为酸性染料 ，主要使细胞质和细胞外基质中的成分着红色 。

伊红（Eosin）是一种酸性染料，能染色细胞质、胶原蛋白及肌肉纤维，使之能在显微镜下观察到。 伊红的名称是由其发明者、 化学家 海因里希·卡罗 以兒時好友安娜·彼得斯（Anna Peters）的外号“ 厄俄斯 ”（Eos）命名的。

Eosin is a fluorescent, xanthene dye which binds to salts with eosinophilic compounds containing positive charges. It is the most suitable stain to combine with an alum hematoxylin to demonstrate the general histological architecture of tissues.

Eosin YS dye is an organic sodium salt that is 2',4',5',7'-tetrabromofluorescein in which the carboxy group and the phenolic hydroxy group have been deprotonated and the resulting charge is neutralised by two sodium ions. It has a role as a fluorochrome and a histological dye.

2025年2月21日 · The Hematoxylin and Eosin (H&E) staining protocol is a standard procedure in histology and pathology laboratories, providing essential contrast for tissue examination under a microscope. This step-by-step guide outlines the entire process, from tissue preparation to slide mounting, ensuring high-quality and reproducible results.

伊红(eosin)是一种化学合成的酸性染料，在水中解离成带负电荷的阴离子，可以和蛋白质氨基上带正电荷的阳离子结合，从而使细胞胞浆染成不同程度的红色或粉红色，与苏木素染色液染色形成的蓝色细胞核形成鲜明对比，从而使苏木素伊红(HE)染色成为病理组织 ...

eosin， 英语 单词，主要用作为名词，意为曙红（鲜红色的染料）。 N a red crystalline water-insoluble derivative of fluorescein. Its soluble salts are used as dyes. Formula: C20H8Br4O5 曙红 (Also called bromeosin) [1] A coronal section of a human brain is stained with hematoxylin and eosin. 人脑冠部经过苏木精和曙红染色。

它是一种荧光染料，常用于生物学和组织学领域作为染色剂，尤其是在显微镜下观察细胞和组织结构。 Eosin的制法通常通过合成路线来实现，一般从蒽醌类化合物出发，通过一系列反应合成得到。 常见的合成路线包括从2-氨基-1,4-二羧基酚酮经过多步反应合成而得。 安全信息：Eosin一般认为是相对安全的化合物。 当处理氨基酸的高浓度溶液时，避免接触皮肤和眼睛。 应注意避免吸入其粉尘，及时清洗残留在皮肤上的Eosin。 在使用过程中应遵守好实验室安全操作规范。 最后 …
