Characterization of nucleic acid higher order structure by gas-phase H/D exchange in a quadrupole-FT-ICR mass spectrometer
(Wiley Subscription Services, Inc., A Wiley Company, 2009-04)
Nucleic acid higher order structure is of intense interest in antisense and antigene strategies toward novel chemotherapeutic agents. Understanding how structural characteristics affect solution-phase properties is essential ...
Revisiting the Response Mechanism of Polymeric Membrane Based Heparin Electrodes
(WILEY‐VCH Verlag, 2012-01)
Potentiometric membrane electrodes that respond to heparin and other polyanions were introduced in the early 1990s. Herein, the mechanism of polymer membrane electrode type heparin sensors is revisited. The extraction/diffusion ...
Oligoribonucleotides with 2′‐O‐(tert‐Butyldimethylsilyl) Groups
(Wiley Periodicals, Inc.IRL Press,, 2000-07)
The chemical synthesis of oligoribonucleotides on solid support is routinely performed via the phosphoramidite method. However, the additional 2‐OH function of the ribofuranosyl sugar requires suitable protection during ...
Determination of Binding Mode: Intercalation
(Academic PressWiley Periodicals, Inc., 2000-02)
A small molecule can be assumed to bind to DNA by intercalation between base pairs if it causes lengthening and unwinding of the DNA helix and undergoes changes in its spectral properties, such as DNA‐induced hypochromism ...
Early events of Bacillus anthracis germination identified by time-course quantitative proteomics
(WILEY-VCH Verlag, 2006-10)
Germination of Bacillus anthracis spores involves rehydration of the spore interior and rapid degradation of several of the protective layers, including the spore coat. Here, we examine the temporal changes that occur ...
Cellular Delivery of Locked Nucleic Acids (LNAs)
(Wiley Periodicals, Inc., 2002-06)
Locked nucleic acids (LNAs) are RNA derivatives that have an O‐methylene linkage between the 2 and 4 positions of the ribose. This leads to exceptionally high‐affinity binding to complementary sequences. They are synthesized ...
Electron detachment dissociation of fluorescently labeled sialylated oligosaccharides
(WILEY‐VCH Verlag, 2011-12)
We explored the application of electron detachment dissociation (EDD) and infrared multiphoton dissociation (IRMPD) tandem mass spectrometry to fluorescently labeled sialylated oligosaccharides. Standard sialylated ...
Synthesis and performance of a thermosetting resin: Acrylated epoxidized soybean oil curing with a rosin‐based acrylamide
(Wiley Periodicals, Inc., 2017-03-05)
A synthesized rosin‐based polymeric monomer, N‐dehydroabietic acrylamide (DHA‐AM), was introduced into an acrylated epoxidized soybean oil (AESO)/DHA‐AM system to afford a thermosetting resin through thermocuring. Different ...
Ring-opening polymerization of epoxy end-terminated poly(ethylene oxide) as a route to highly crosslinked materials with exceptional swelling behavior (II)
(John Wiley & Sons, Ltd., 2007-08)
Highly swellable poly(ethylene oxide) (PEO) gels were prepared by anionic ring-opening polymerization of diepoxy end-capped PEO (3400 g mol −1 ) and PEO (8000 g mol −1 ) using dianionic glycerol and glycolic acid initiators ...
