Glutathione Peroxidase-Based Amperometric Biosensor for the Detection of S -Nitrosothiols
(WILEY-VCH Verlag, 2006-11)
A new biosensor is described for the detection of S -nitrosothiols (RSNOs) based on their decomposition by immobilized glutathione peroxidase (GPx), an enzyme containing selenocysteine residue that catalytically produces ...
Fragmentative and stereochemical isomerization probes for homolytic carbon to phosphorus bond scission catalyzed by bacterial carbon-phosphorus lyase
(Elsevier, 1987-12)
Three bacterial strains, Agrobacterium radiobacter, Klebsiella oxytoca, and Kluyvera ascorbata, isolated by enrichment culture for carbon to phosphorus bond cleavage ability, were analyzed for the mode of C---P bond fission. ...
Evaluating hydrogen bond interactions in enzymes containing Mn(III)-histidine complexation using manganese-imidazole complexes
(Springer-Verlag; SBIC, 2003-02)
It is often difficult to control hydrogen bond interactions in small molecule compounds that model metalloenzyme active sites. The imidazole-containing ligands 4,5-dicarboxyimidazole (H 3 DCBI) and 4,5-dicarboxy- N ...
Proteomic profiling identifies breast tumor metastasis-associated factors in an isogenic model
(WILEY-VCH Verlag, 2007-01)
A combination of LC and MS was applied to an isogenic breast tumor metastasis model to identify proteins associated with a cellular phenotype. Chromatofocusing followed by nonporous-RP-HPLC/ESI-TOF MS was applied to cell ...
Direct chemical analysis of UV laser ablation products of organic polymers by using selective ion monitoring mode in gas chromatography/mass spectrometry
(Elsevier, 1994-02)
Trace quantitites of laser ablated organic polymers were analyzed by using commercial capillary column gas chromatography / mass spectrometry; the instrument was modified so that the laser ablation products could be ...
The design and performance of an ion trap storage--reflectron time-of-flight mass spectrometer
(Elsevier, 1994-02-24)
The design and performance of an ion trap storage--reflectron time-of-flight mass spectrometer (IT--RETOF MS) combination have been explored for detection of ions generated from both internal and external ionization sources. ...
Lectin-based homogeneous enzyme-linked binding assay for estimating the type and relative amount of carbohydrate within intact glycoproteins
(Elsevier, 1992-04)
The feasibility of using a new lectin-based homogeneous enzyme-linked binding assay for estimating the type and relative amount of specific carbohydrate structures within intact glycoproteins is examined. Malate ...
