Biosensor technologies based on optical readout are widely used in protein–protein interaction studies. Here we describe a
fast and simple approach to the creation of oriented interfacial architectures for surface plasmon resonance (SPR) transducers,
based on conventional biochemical procedures and custom reagents. The proposed protocol permits the oriented affinity-capture
of GST fusion proteins by a specific antibody which is bound to protein A, which in turn has been immobilized on the transducer
surface (after the surface has been modified by guanidine thiocyanate). The applicability of the method was demonstrated by
studying the interaction between retinoblastoma tumor suppressor protein (pRb) and MRS18-2 proteins. The formation of the
pRb–MRS18-2 protein complex was examined and the pRb binding site (A-box–spacer–B-box) was mapped. We have also shown that
MRS18-2, which was detected as the Epstein–Barr virus-encoded EBNA-6 binding partner using the yeast two-hybrid system, binds
to pRb in GST pull-down assays. 相似文献

Previous theoretical work on energy cluster formation at high rotational excitation in the vibrational ground state of PH3 [S.N. Yurchenko, W. Thiel, S. Patchkovskii, P. Jensen, Phys. Chem. Chem. Phys. 7 (2005) 573] is extended to BiH3 and SbH3. By means of variational calculations of the rotation–vibration energies based on ab initio potential energy surfaces, we analyze the rotational energy clustering of BiH3 and SbH3 at J 70 for a number of vibrational states. We show that BiH3 and SbH3, with their pronounced local mode behaviour, exhibit cluster formation already at moderate rotational excitation. In addition, owing to its quasi-spherical-top character, BiH3 undergoes an imperfect bifurcation at high J. This gives rise to an energy cluster type not present in PH3 and SbH3. We present a semi-classical approach to the construction of the rotational energy surfaces for vibrationally excited states. 相似文献

Previous theoretical and experimental studies have shown that some vibrating systems can be stabilized by zero-averaged periodic parametric excitations. It is shown in this paper that some zero-mean random parametric excitations can also be useful for this stabilization. Under some conditions, they can be even more efficient compared to the periodic ones. Two-mass mechanical system with self-excited vibrations is considered for this comparison. The so-called bounded noise is used as a model of the random parametric excitation. The mean-square stability diagrams are obtained numerically by considering an eigenvalue problem for large matrices. 相似文献

The interaction of arylbis(5,5-dimethylcyclohexane-1,3-dion-2-yl)methanes with o-phenylenediamine and o-aminophenol leads to the preparation of 3,3-dimethyl-11-aryl-2,3,4,5,10,11-hexahydrobenzo[b,e]-1,4-diazepin-1-ones and 3,3,6,6-tetramethyl-9-aryl-10-(2-hydroxyphenyl)-2,4,5,7,9-decahydroacridine-1,8-diones respectively. A one-pot method is proposed for the synthesis of derivatives of hexahydrodibenzo[b,e]-1,4-diazepin-1-ones. The structure of the first member of this series was confirmed by X-ray diffraction analysis.Translated from Khimiya Geterotsiklicheskikh Soedinenii, No. 12, pp. 1798–1808, December, 2004. 相似文献

Catalysts containing large amounts of surface acid sites are highly active, but in their presence equal yields of methylmercaptane and dimethyl sulfide are obtained. Catalysts containing predominantly strong basic sites on their surfaces are less active but more selective towards methylmercaptane formation than the former catalysts.

Mössbauer spectroscopic studies of the state of Pt–Sn catalyst for hydrocarbon conversion supported on prechlorinated -Al2O3 indicate that, unlike nonchlorinated Al2O3, this system is much more reduced and besides Pt3Sn–PtSn2, its surface contains sigfificant amounts of Sn(II) and Sn(IV) chlorides bonded to the surface.

By IR and Raman spectroscopy it has been shown that excess MoO3 is bound molecularly on the surface of CdMoO4, presumably on sites of C2 and Ci symmetry. This increases the activity and selectivity of the catalyst in methanol oxidation to formaldehyde.

The adsorption of water, methyl and i-propyl alcohol vapours has been studied on the surface of titanosilicas produced by various methods, as well as on the surface
of pure silicon and titanium oxides. Based on findings of the studies, it was concluded that the presence on the surface of
pyrogenic titanosilicas (TAS) of hydrolytically unstable Si-O-Ti bonds is responsible for their increased adsorption activity
towards water molecules. A dissociative adsorption of H2O on titanosiloxane bridges is accompanied by an appearance of additional groups ≡SiOH and ≡TiOH, which, in turn, become sites
of adsorption of subsequent water molecules.
