El reactivo de DTNB o Elman se puede utilizar para cuantificar tioles en proteínas, células y plasma mediante mediciones de absorción. Forma fácilmente un disulfuro mezclado con tioles, liberando el ácido cromóforo 5-merapto-2-nitrobenzoico (absorción máxima de 410 nm). Solo se modifican los tioles proteicos que son accesibles a este reactivo soluble en agua.
Para uso exclusivo en investigación. No apto para uso en procedimientos diagnósticos.

A general strategy for site-specific double labeling of globular proteins for kinetic FRET studies.
Authors:Ratner V,Kahana E,Eichler M,Haas E
Journal:Bioconjugate chemistry
PubMed ID:12236801
Site-directed mutagenesis provides a straightforward means of creating specific targets for chemical modifications of proteins. This capability enhanced the applications of spectroscopic methods adapted for addressing specific structural questions such as the characterization of partially folded and transient intermediate structures of globular proteins. Some applications such as the steady state ... More
Reactivity of mitochondrial sulfhydryl groups toward dithionitrobenzoic acid and bromobimanes under oligomycin-inhibited and uncoupling conditions.
Authors:Freisleben HJ, Fuchs J, Mainka L, Zimmer G
Journal:Arch Biochem Biophys
PubMed ID:2845867
Thiol reactivity was determined in rat heart mitochondria using chromophores of differing polarities: monobromobimane (MB), dithionitrobenzoate (NbS2), and bromobimane-q (MQ). The purpose of this study is to correlate reaction rates of protein thiols in the mitochondrial membrane with the oligomycin-inhibited and uncoupled states: In all cases investigated the reactivity of ... More
Sulfhydryl groups of rabbit liver arylsulfatase A.
Authors:Waheed A, Van Etten RL
Journal:Biochim Biophys Acta
PubMed ID:2864083
Rabbit liver arylsulfatase A (aryl-sulfate sulfhydrolase, EC 3.1.6.1) monomers of 130 kDa contain two free sulfhydryl groups as determined by spectrophotometric titration using 5,5'-dithiobis(2-nitrobenzoate) and by labeling with the fluorescent probe 5-(iodoacetamidoethyl)aminonaphthalene-1-sulfonic acid. Fluorescence quenching data indicate that the reactive sulfhydryl is present in proximity to one or more tryptophan ... More
Actin can act as a cofactor for a viral proteinase in the cleavage of the cytoskeleton.
Authors:Brown MT, McBride KM, Baniecki ML, Reich NC, Marriott G, Mangel WF
Journal:J Biol Chem
PubMed ID:12191991
'Cytoskeletal proteins are exploited by many viruses during infection. We report a novel finding that actin can act as a cofactor for the adenovirus proteinase (AVP) in the degradation of cytoskeletal proteins. Transfection studies in HeLa cells revealed AVP localized with cytokeratin 18, and this was followed by destruction of ... More
