A natural product, stilbene glycoside (2,3,5,4'-tetrahydroxydiphenylethylene-2-O-glucoside, TBG), has been evaluated for the first time as a potential substrate for horseradish peroxidase (HRP)-catalyzed fluorogenic reactions. The properties of TBG as a fluorogenic substrate for HRP and its application in a fluorometric enzyme-linked immunosensing system were compared with commercially availabl...

Since Gordon and his colleagues' (1) description of the association of thyroxine (T4) with an a-globulin [later termed "thyroxine-binding globulin" (TBG) ] in 1952, thyroid hormone transport has been the subject of intense study. The demonstration of "thyroxine-binding prealbumin" (TBPA) by Ingbar (2) in 1958 provided further understanding of the binding of T4 by the plasma proteins. It has als...

Thyroxine-binding alpha globulin (TBG) in human serum was isolated from Cohn fractions IV-5,6 and IV-4 by (1) chromatography on carboxymethyl (CM) cellulose, (2) gel filtration on Sephadex G-200, (3) chromatography on diethylaminoethyl-Sephadex, (4) a novel procedure of "double-gel" electrophoresis, and (5) preparative polyacrylamide gel electrophoresis. The protein was homogeneous by analytica...

Spontaneous orbital magnetism observed in twisted bilayer graphene (tBG) on nearly aligned hexagonal boron nitride (BN) substrate builds top of the electronic structure resulting from combined G/G and G/BN double moire interfaces. Here we show that tBG/BN commensurate patterns can be classified into two types, each favoring narrowing either conduction or valence bands average, obtain evolution ...

Graphene/silicon hybrid photodetector operating at communication wavelength has attracted enormous attention recently due to its potential realize bandwidth larger than 100 GHz. However, the responsivity is intrinsically limited by low absorption from atomic-thick graphene monolayer, which imposes significant obstacles towards practical application. Although plasmonic structures been widely app...

We study the stability and electronic structure of magic-angle twisted bilayer graphene on hexagonal boron nitride (TBG/BN). Full relaxation has been performed for commensurate supercells heterostructures with different twist angles ($\theta'$) stackings between TBG BN. find that slightly misaligned configuration $\theta' = 0.54^\circ$ AA/AA stacking globally lowest total energy due to construc...

Serum triiodothyronine (T(3)) kinetics in man have been difficult to define presumably due to the interference of iodoproteins generated during the peripheral metabolism of T(3). The use, in the present study, of an anion-column chromatographic method for separation of serum T(3) as well as thyroxine (T(4)) from these iodoproteins has overcome this technical handicap. Simultaneous measurement o...
