114616-31-8

A fluorescein introduction reagent. It can be used for labeling primary amines.

6-[Fluorescein-5(6)-carboxamido]hexanoic acid N-hydroxysuccinimide ester (FHS) is used as a reagent to conjugate the fluorophore 6-[Fluorescein-5(6)-carboxamido]hexanoic acid to molecules.6-[Fluorescein-5(6)-carboxamido]hexanoic acid is used as a fluorescein-based fluorescent label for proteins that can be analyzed in applications such as quenching experiments. The hexanoic spacer renders the reactive group more accessible to nucleophiles on biopolymers.

Reagent for introducing the fluorescein label; the spacer renders the reactive group more accessible to nucleophiles on biopolymers.
