一般說明
5(6)-羧基荧光素，也称为5(6)-FAM，是一种荧光示踪剂，可作为5-羧基荧光素和6-羧基荧光素异构体的混合物。5(6)-羧基荧光素的荧光是由它的杂蒽部分决定的。 5(6)-羧基荧光素有两个特性:
- 它有两个波长的最大吸光度（465 和 490nm）。
- 它的荧光发射在 515nm处（最大）随 pH 值的变化而增大，生理范围为 6-7.4。
應用
5(6)-羧基荧光素在体内用于肿瘤细胞和正常细胞的表征。它标记通过n -羟基琥珀酰亚胺（NHS）酯介导衍生化衍生的蛋白质。 5(6)-羧基荧光素适用于检测细胞活力，同时开发体外驱虫药试验。

We evaluated four different fluoroprobes to determine their capabilities and limitations in measuring intracellular pH by the fluorescent indicator technique. In vitro, carboxyfluorescein, dimethylcarboxyfluorescein, biscarboxyethyl carboxyfluorescein, and 4-methylumbelliferone (4MU) all showed comparably intense fluorescence and excellent pH sensitivity near their

The pH of the interstitial fluid of malignant tumours tends to be lower than that of normal tissue and is depressed by glucose administration. This study aimed to evaluate the effectiveness of dual-wavelength fluorometry using a pH-dependent indicator (5,6-carboxyfluorescein: 5,6-CF)

A new in vitro assay for anthelmintic activity using Caenorhabditis elegans is based on the ability of 5(6)-carboxyfluorescein diacetate (CFDA) to indicate the worm's viability. It is shown for the first time that the treatment of a suspension of worms

Adhesion of Staphylococcus aureus to blood vessels under shear stress requires von Willebrand factor (VWF). Several bacterial factors have been proposed to interact with VWF, including VWF-binding protein (vWbp), a secreted coagulase that activates the host's prothrombin to generate fibrin.

Fluorescein and carboxyfluorescein have found recent application as probes of intracellular pH. The present study examines several parameters required for interpretation of the spectral information derived from fluorescein and carboxyfluorescein generated intracellularly from their permeant diacetate derivatives.
