Descrizione generale

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.

Applicazioni

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

Lys-553 of skeletal muscle myosin subfragment 1 (S1) was specifically labeled with the fluorescent probe FHS (6-[fluorescein-5(and 6)-carboxamido]hexanoic acid succinimidyl ester) and fluorescence quenching experiments were carried out to determine the accessibility of this probe at Lys-553 in both the

Programed cell death is a critical and unavoidable part of life. One of the most widely used markers for dying cells, by apoptosis or pyroptosis, is the redistribution of phosphatidylserine (PS) from the inner to the outer plasma membrane leaflet.

Immune complexes were formed between dinitrophenylated human serum albumin (DNP-HSA) and polyclonal rabbit immunoglobulin G (IgG) anti-DNP antibodies at antibody excess. The antigen was labelled with isotope (125I-tyramine-cellobiose) or fluorochrome, (6-[fluorescein-5-(and-6)-carboxamido] hexanoic-acid, succinimidyl ester). The radiolabelled antigen, native or antibody
