别名: 伊红 Y 二钠盐;四溴荧光黄;曙红Y;曙红微黄;酸性红87;水溶伊红;朝红;四溴荧光素二钠;曙红钠盐;2′,4′,5′,7′-四溴荧光素二钠盐;Red No. 22

CAS号: 17372-87-1

分子式: C₂₀H₆Br₄Na₂O₅

介绍: 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.

用途: 用作生物染色剂。也用作吸附指示剂，用于沉淀滴定测定Br-、I-、SCN-、MoO 、Ag＋等。用作显色剂，用于荧光光度法测定Ag＋、Pb2＋、Mn2＋、Zn2＋等。

特定比重: 1.015

贮存: 密封保存。

敏感性: 对湿度敏感

可溶性: 易溶于水，稍溶于醇，不溶于醚，浓的水溶液为深棕红色，其稀溶液（1：501）为黄红色显绿色荧光，醇溶液有很强的绿色荧光。

温馨提示：不可用于临床ZL。
