Descrizione generale

Fluorescein 5(6)-isothiocyanate, also known as FITC, is a weakly acidic hydroxyxanthene whose overall size is small, with both carboxylic acid and isothiocyanate substituents on the pendant phenyl ring. The dye has a moderately sized, nonplanar aromatic system. The isothiocyanate group reacts with nucleophilic substituents (e.g. amino, hydroxyl, thiol) of biomolecules to be attached as a fluorescent label. The maximum emission of the dye is at 519nm in the same solvent.

Applicazioni

Fluorescein 5(6)-isothiocyanate (FITC) labelled molecules are used in non-microscopic immunoassays and physiological tracing experiments. FITC is widely used in flow cytometry experiments for staining proteins, nuclei, and subnuclear particles. White blood cells (WBCs) are marked with FITC to study their response toward a chemoattractant, eventually being measured.
For fluorescent labeling of proteins (e.g. immunofluorescence); H Protein labeling for gel chromatography

Hematopoietic stem cells (HSCs) possess the ability to generate all hematopoietic cell types and to self-renew over long periods, but the mechanisms that regulate their unique properties are incompletely understood. Herein, we show that homozygous deletion of the miR-29a/b-1 bicistron

Epidemiological studies indicate that statins, cholesterol-lowering drugs, prevent aggressive prostate cancer and other types of cancer. Employing essentially non-prostate cell lines, we previously showed that statins rapidly downregulate nuclear levels of phosphorylated Akt via P2X7, a purinergic receptor recently implicated
