El patrón de fluoresceína con trazabilidad conforme al NIST se suministra como una solución calibrada de 50 μM de fluoresceína en un tampón de 100 mM de borato sódico, pH 9,5. En estas condiciones, la fluoresceína está completamente ionizada y, por tanto, está en su forma más fluorescente. Este patrón cumple los estrictos criterios establecidos por el National Institute of Standards and Technology (NIST, Instituto estadounidense de normas y tecnología) y es directamente trazable conforme al material de referencia del patrón 1932 (SRM 1932). El patrón fluorescente con trazabilidad conforme al NIST utilizarse para evaluar la variación diaria o entre experimentos en instrumentación basada en fluorescencia, así como para determinar el valor MESF (Molecules of Equivalent Soluble Fluorochrome, moléculas de fluorocromo soluble equivalente) para una solución experimental.

Abstract
Novel fluorometric assay for hydroxyl radical prevention capacity using fluorescein as the probe.
Journal:J Agric Food Chem
PubMed ID:11982397
'A novel fluorometric method has been developed to evaluate hydroxyl radical prevention capacity using fluorescein (FL) as the probe. The hydroxyl radical is generated by a Co(II)-mediated Fenton-like reaction, and the hydroxyl radical formation under the experimental condition is indirectly confirmed by the hydroxylation of p-hydroxybenzoic acid. The fluorescence decay

This communication describes the determination of corrected fluorescence emission spectra and fluorescence quantum yields for fluorescein, sulforhodamine 101 and other standard fluorescent dyes.
Development and validation of an improved oxygen radical absorbance capacity assay using fluorescein as the fluorescent probe.
Journal:J Agric Food Chem
PubMed ID:11599998
An improved method of oxygen radical absorbance capacity (ORAC) assay has been developed and validated using fluorescein (3',6'-dihydroxyspiro[isobenzofuran-1[3H],9'[9H]-xanthen]-3-one) as the fluorescent probe. Our results demonstrate that fluorescein (FL) is superior to B-phycoerythrin. The oxidized FL products induced by peroxyl radical were identified by LC/MS, and the reaction mechanism was determined
Fluorescein as a model molecular calculator with reset capability.
Journal:Nat Mater
PubMed ID:16155575
The evolution of molecules capable of performing boolean operations has gone a long way since the inception of the first molecular AND logic gate, followed by other logic functions, such as XOR and INHIBIT, and has reached the stage where these tiny processors execute arithmetic calculations. Molecular logic gates that
