General description

6-[Fluorescein-5(6)-carboxamido] hexanoic acid N-hydroxysuccinimide ester (FNHS) is a fluorescent label, also known as fluorescein. FNHS max. excitation is at 490 nm with emission max. at 514nm. 6-[Fluorescein-5(6)-carboxamido] hexanoic acid N-hydroxysuccinimide ester binds covalently with primary amines.

Application

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