Novel spectrophotometric technique for rapid determination of extractable PHA using Sudan black dye
(Elsevier Science, 2017-06)
Classical techniques employed to determine the amount of extractable poly(hydroxyalkanoate)s (PHAs) from cells, are laborious and destructive. Sudan black staining is commonly used in the laboratory to investigate the ...
HIGH-PERFORMANCE MODULAR SPECTROPHOTOMETRIC FLOW CELL
(Royal Soc ChemistryCambridgeInglaterra, 1991)
Improved intracellular PHA determinations with novel spectrophotometric quantification methodologies based on Sudan black dye
(Elsevier Science, 2018-05)
The presence of intracellular polyhydroxyalkanoates (PHAs) is usually studied using Sudan black dye solution (SB). In a previous work it was shown that the PHA could be directly quantified using the absorbance of SB fixed ...
Flow-batch technique for the simultaneous enzymatic determination of levodopa and carbidopa in pharmaceuticals using PLS and successive projections algorithm
(Elsevier Science, 2008-05)
An enzymatic flow-batch system with spectrophotometric detection was developed for simultaneous determination of levodopa [(S)-2 amino-3-(3,4-dihydroxyphenyl)propionic acid] and carbidopa [(S)-3-(3,4-dihydroxyphenyl)-2-h ...
Measurement of glycogen synthase activity in crude extracts by CE
(WILEY-V C H VERLAG GMBH, 2007-02-11)
Glycogen synthase catalyzes the incorporation of UDP-glucose into glycogen. The activity
of the enzyme is usually measured either by a spectrophotometric method or by a radioassay.
The first one is not suitable because ...
Multilayered particle-packed column: Evaluation and comparison with monolithic and core-shell particle columns for the determination of red azo dyes in Sequential Injection Chromatography
(Wiley VCH Verlag, 2017-03)
A recently presented new type of "multilayered" organic-inorganic hybrid silica particle packed column YMC-Triart C18 (50 mm × 4.6 mm, 5 μm) was used for the development of a sequential injection chromatography method for ...
Desenvolvimento de biossensores à base de filmes poliméricos, nanotubos de carbono e nanopartículas de ouro
(Universidade Federal de São CarlosBRUFSCarPrograma de Pós-Graduação em Química - PPGQ, 2013-06-07)
In this work was described the development of new architectures for biosensors, using nanomaterials. The enzyme of interest was immobilized on glassy carbon electrode modified with multi-walled carbon nanotubes chemically ...
