Application

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。

General description

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。

Calcein-acetoxymethylester (calcein-AM) is a non-fluorescent, cell permeant compound, which is converted by intracellular esterases into calcein, an anionic fluorescent form. It is used in microscopy and fluorometry and provides both morphological and functional information of viable cells. In this study
