Antibodies against synthetic peptides derived from the cDNA sequence of interferon-induced 2',5'-oligo(A) synthetase, and which immunoprecipitate the native enzyme activity, were found to detect multiple enzyme forms in denaturing electrophoretic immunoblots. In some human cell lines, four different interferon-induced proteins of 40, 46, 67, and 100 kDa were found to react with the same peptide...

The semiconducting properties of molecular material prototypes for graphene nanoribbons are rationalized by quantum-chemical calculations. The present contribution focuses on the hole transport properties of circum(oligo)acenes and compares the intrinsic efficiency of these materials for charge transport in the hopping regime with respect to the (oligo)acenes parent compounds. The results at th...

The rectifying properties of α,ω-dithiol terminated oligo(phenylene ethynylene) molecules sandwiched between heterometallic electrodes, including the molecular length and side group effects, are theoretically investigated using the fully self-consistent nonequilibrium Green's function method combined with density functional theory. The results show nonlinear variation with changes in molecule l...

The condition of oligo-micelle formation of sodium di-isodecyl sulfosuccinate (SDIDS) emulsifier in hydroalcoholic solutions is used to study particle formation of vinyl chloride emulsion polymerization in a batch reactor. The change on micellization behavior was investigated by critical micelle concentration (CMC) and zeta potential parameters. To detect the occurrence of secondary nucleation ...

Purified preparations of L cell virions (LCV) were found to possess an associated DNA polymerase activity. This enzyme was active with poly(C).oligo(dG) and poly(Cm).oligo(dG) and was able to transcribe poly(A).oligo(dT). Endogenous DNA synthesis was also demonstrable in disrupted virion preparations but this reaction was enhanced, rather than inhibited, by RNase pre-treatment. The effects of v...

Oligo kernels for biological sequence classification have a high discriminative power. A new parameterization for the K-mer oligo kernel is presented, where all oligomers of length K are weighted individually. The task specific choice of these parameters increases the classification performance and reveals information about discriminative features. For adapting the multiple kernel parameters ba...

Physical properties (chemical adsorption rate, viscoelasticity, thickness, and conformation) for self-assembled monolayers (SAMs) of mercapto oligo (ethylene oxide) methyl ethers on gold were determined by quartz crystal microbalance (QCM). The values of thickness, shear viscosity and elastic shear modulus of SAMs increase with unit number of oligo (ethylene oxide) segment. However, the chemica...

Chitosan, a natural and abundant biopolymer has been long explored as biocompatible material for the preparation of drug delivery devices. This strategy mostly accomplished using chemically crosslinked chitosan leading to more stable scaffolds. However, crosslinking shown reduce both biocompatibility swelling. In this work was with novel crosslinkers, based on oligo-oxazolines glycidyl methacry...

3′,5′-Cyclic GMP spontaneously nonenzymatically polymerizes in a base-catalyzed reaction affording G oligonucleotides. When reacted with fully or partially sequence-complementary RNA (oligo C), the abiotically generated oligo G RNA displays a typical ribozyme activity consisting of terminal ligation accompanied by cleavage of an internal phosphate site of the donor oligonucleotide stem upon att...
