一般說明

钙黄绿素-AM，也称钙黄绿素-乙酰甲酯，是一种不发射荧光的分子，在细胞内酯酶的作用下会转化为阴离子荧光形式。在实验过程中它可以使黏附细胞连续成像。 钙黄绿素-AM是一种必不可少的染料，可在保持细胞膜完整的情况下将钙黄绿素引入活细胞。 钙黄绿素-AM中发射荧光的部分位于细胞间隙，在以酯酶依赖型关系在细胞中捕获，之后显示出细胞中的细胞毒性活性。

應用

钙黄绿素-AM是一种细胞活力染料，也可作为多药外排性转运体（multidrug efflux transporter）的中性底物。在癌症研究中，它可用作多药耐药蛋白MRP的中性底物。 用于测定人红细胞活力和老化的荧光测试法是以钙黄绿素-AM为探针。
钙黄绿素的非荧光细胞渗透衍生物，水解后发出荧光。 用作多药耐药蛋白MRP的中性底物；用于肿瘤研究。
