Previous studies (1) of glutamic acid metabolism suggested an investigation of the role of this amino acid and its thio esters (2, 3) in amino acid incorporation. The studies by Zamecnik et al. (4, 5) on amino acid incorporation into freshly prepared rat liver microsomes in the presence of the soluble cell fraction and an ATPl-regenerating system appeared to provide a suitable test system for o...

The surface modified hydrophilic zinc sulfide nano powder was prepared by hydrothermal method, and the corresponding sulfide/polyurethane organic-inorganic composite transparent coating via in-situ polymerization. structure of ZnS Nanoparticles were characterized Infrared Spectroscopy, X-Ray Diffraction, Laser Particle Size Analyzer Scanning Electron Microscopy. optical properties measured Ultr...

Ti3C2Tx MXene was synthesized and the 2D layers were hybridized with Au nanoparticle (AuNP) through in-situ method. The study successfully prepared layer same TEM captured as well. Polyimide/MXene-AuNP (PI/Mxene-AuNP) transducing conducting nanocomposite thin film evaluated new material’s capability to use a for biosensing application. bioreceptor on delay line area of SAW device by covalently ...

A new method for the determination of ascorbic, dehydroascorbic and 2.3-diketogulonic acids in animal tissues, blood and urine is described. The material for analysis is homogenized in the presence of stannous chloride in trichloracetic acid and the extract is divided into three aliquots: in one part the ascorbic acid is converted into dehydroascorbic acid by oxidation with bromine water, in th...

Reagents. Thioglycolic acid (TGA), Bovine serum albumin (BSA), imidazole, N-(3dimethylaminopropyl)-N’-ethyl-carbodiimide hydrochloride (EDC), Nhydroxysuccinimide (NHS), (+)-Biotin N-hydroxysuccinimide were purchased from Sigma-Aldrich. EDC and NHS were dissolved in water immediately before use. Human prostate-specific antigen (PSA), two mouse antihuman total PSA monoclonal antibodies (primary c...

This work elucidated the detailed electrochemiluminescence (ECL) process of the thioglycolic acid-capped CdSe quantum dots (QDs) film/peroxide aqueous system. The QDs were first electrochemically reduced to form electrons-injected QDs approximately -1.1 V, which then reduced hydrogen peroxide to produce OH* radical. The intermediate OH* radical was a key species for producing holes-injected QDs...
