FLUORESCEIN-5(6)-CARBOXAMIDOCAPROIC ACID N-SUCCINIMIDYL ESTER

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

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.
