General description

荧光素(游离酸 CI 45350)是一种呫吨染料。荧光素(游离酸)分子可分为两部分。一部分含有呫吨基团,其可充当荧光团,而另一部分带有苯基团,其是荧光控制基团。

Application

荧光素(游离酸)已用作视网膜成像中的染色剂。
荧光素(游离酸)被广泛用作许多活细胞和组织的荧光染色和跟踪。它也适合作为研究胆管运动的标志物。临床应用包括评估眼表和描绘缺乏血脑屏障的脑区域,以实现准确的恶性胶质瘤手术切除。荧光素血管造影有助于研究视网膜血液供应的变化。荧光素还可以作为一种生理示踪剂来表征鲑鱼的肠通透性(Schep 等,1998),并用于房水流量的荧光光度法测量。它被广泛用作量子产量标准。
