Fluorescein (FAM) is a bright fluorophore that has found an extremely wide application in life science research. The fluorophore is hydrophilic and its derivatives possess good solubility in aqueous buffers.

Fluorescein is compatible with a wide variety of fluorescent instrumentation – most instruments are equipped with FAM channel filters.

This product contains the pure 6-isomer of fluorescein.

荧光素 (FAM) 是一种明亮的荧光团,在生命科学研究中有着极其广泛的应用。 荧光团是亲水性的,其衍生物在水性缓冲液中具有良好的溶解性。

荧光素与多种荧光仪器兼容——大多数仪器都配备了 FAM 通道过滤器。
