BCECF AM (ultra pure)

BCECF AM (2’,7’-bis-(2-carboxyethyl)-5-(and-6)-carboxyfluorescein acetoxymethyl ester) is a well established fluorescent probe that enables ratiometric monitoring of cellular pH. Intracellular pH plays an important role in modulating cellular events, including growth, calcium regulation, enzymatic activity, receptor-mediated signal transduction, ion transport, endocytosis, chemotaxis, adhesion and other cellular processes. Once inside, cellular esterases cleave the AM groups yielding a more hydrophilic BCECF trapped inside the cell. Wavelength Maxima: Excitation 505nm, Emission 520nm
