(6)-羧基熒光素 (5(6)-Carboxyfluorescein)用于測量細胞內(nèi)pH（pHi）和 樹狀大分子聚集和吸收 等過程的變化，為細胞內(nèi)pH探針，也可以用于制備熒光肽和蛋白質(zhì)偶聯(lián)物。熒光波長:λex 492 nm, λem 517 nm in 0.1 M Tris pH 8.0。

5(6)-Carboxyfluorescein, also known as 5(6)-FAM, is a fluorescent tracer and available as a mixture of 5-Carboxyfluorescein and 6-Carboxyfluorescein isomers. The fluorescence of 5(6)-Carboxyfluorescein is determined by the xanthene moiety. 5(6)-Carboxyfluorescein has two characteristic properties.
