BCECF AM，即2',7'-bis-(2-carboxyethyl)-5-(and-6)-carboxyfluorescein,acetoxymethyl ester，是最常用的检测细胞内pH的荧光探针。
本BCECF AM(pH荧光探针)是配制于无水DMSO(anhydrous DMSO)中的储存液，浓度为5mM。
BCECF AM是一种可以穿透细胞膜的荧光染料。BCECF AM没有荧光，进入细胞后可以被细胞内的酯酶剪切形成BCECF，从而被滞留在细胞内。BCECF在适当的pH值情况下可以被激发形成绿色荧光。最大激发波长和发射波长因pH的不同而有所不同，最大激发波长大致在503nm左右，最大发射波长大致在520nm左右，实际检测时推荐使用的激发波长为488nm，发射波长为535nm。BCECF在不同pH条件下的发射光谱参考下图。

BCECF AM不仅被广泛用于哺乳动物细胞的研究，也有报道用于动物组织、植物细胞、细菌和酵母等的细胞内pH水平检测。在有细胞内pH变化的细胞毒性、细胞凋亡、细胞粘附、药物抵抗、细胞趋化等过程中BCECF AM被广泛应用。
用于细胞内pH检测时，常用的BCECF AM的浓度为1-10μM。
