Major histocompatibility complex (MHC) tetramer technology is critical for characterization of antigen-specific T cells. In the present study we reported the successful generation of HLA-A*0203 tetramer loaded with Epstein-Barr virus EBNA3(596-604) peptide (SVRDRLARL, SVR). Prokaryotic expression vector for the ectodomain of the heavy chain of HLA-A*0203 fused with a BirA substrate peptide (HLA...

In this work, the synthesis and characterization of a compact, ferrocene tetramer linear viologen polymer is reported. The latter material new, 4,4?-bipyridine containing, organo-soluble polymer. As aimed for solubility in nonpolar solvents, 2-ethylhexyl-moiety to promote organosolubility 4-vinylbenzyl serving as polymerizable group are introduced 4,4?-bipyridine. halide anions monomer cation e...

Fluid catalytic cracking (FCC) is one of the major conversion technologies in the oil refinery industry. FCC currently produces the majority of the world's gasoline, as well as an important fraction of propylene for the polymer industry. In this critical review, we give an overview of the latest trends in this field of research. These trends include ways to make it possible to process either ve...

Drop-casting of gold nanoparticle (AuNP) with radical cation moiety a quaterthiophene derivative provided conductive film. The interparticle π-dimer was considered to act as effective conduction paths in the AuNP assembly.

Melittin is the principal protein component of bee venom and is believed to function as a lytic agent. In aqueous salt solution, it is a tetramer of identical peptides, each with 26 amino acid residues. Although its amino acid composition is unusually nonpolar, and although it is believed to integrate into membranes while lysing cells, melittin is water-soluble at neutral pH. Two crystal forms ...

A ZSM-5 molecular sieve composite with a wide pore prepared by the solid phase in-situ synthesis method and fluid catalytic cracking, an FCC catalyst additive same for increasing amount of light olefin yield were investigated. The samples characterized XRD, N2 adsorption/desorption, SEM, NH3-TPD, respectively. results showed that structure was pure MFI-type zeolite material. crystallinity 59.8 ...

Grand canonical Monte Carlo (GCMC) simulations have been performed to investigate the localization and adsorption behavior of benzene and propylene, which are involved in the cumene synthesis process, in purely siliceous MWW zeolite (ITQ-1). From the mass clouds of GCMC simulations, it can be seen that the benzene and propylene molecules show different localization and adsorption behavior in th...

High-viscosity crude oils from the Yablunivske field (Ukraine, Poltava region) have been studied. The were diluted with gas condensate to reduce viscosity, and then various demulsifiers added. It was established that it is expedient dilute oil heavy dehydrate PM-1441 brand A non-ionogenic demulsifier, based on block copolymers of ethylene propylene oxides. dewatering degree found be 95 %.

The exploration of highly efficient catalysts based on nano-sized Ti-rich titanosilicate zeolites with controllable active titanium species is great importance in zeolite catalytic reactions. Herein, we reported an and facile synthesis TS-1 (MFI) by replacing tetrabutyl orthotitanate (TBOT) tetramer (TBOT-tetramer) as the source. introduced TBOT-tetramer slowed down crystallization process, acc...

To the Editor: We wish to substantiate the important observations of LeGatt and Tisdell (1) cautioning against the use of propylene glycol as an internal standard for quantifying ethylene glycol. A 32-yearold woman presented to our emergency department in an agitated state after the ingestion of multiple drugs in an attempted suicide. Gastric lavage and charcoal were administered as well as int...
