    Fluorescent Dye Others
    Calcein is a fluorescent dye and self-quenching probe, used as an indicator of lipid vesicle leakage, and also as a complexometric indicator for titration of calcium ions with EDTA, and for fluorometric determination of calcium. Calcein cannot directly cross the intact cell membrane of a living cell, unlike Calcein-AM (HY-D0041) which is cell-permeable. Calcein can also be used as a model drug for evaluating efficiency and bioavailability of drug delivery systems .
