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 ...
Thermodynamics of iron sulfides I. Heat capacity and thermodynamic properties of Fe9S10 at temperatures from 5 K to 740 K
(Elsevier, 1991-03)
Measurements of the heat capacity of Fe9S10 over the temperature range 5 K to 740 K reveal a first-order structural transition at 495 K and two higher-order transitions with maxima at 534 K and 591 K. The last two are of ...
Studies on the synthesis and structure of cordycepin monophosphate
(Elsevier, 1963)
Cordycepin monophosphate has been synthesized by two methods. One of these was chemical and involved treatment of cordycepin with cyanoethyl phosphate in the presence of N,N'-dicyclohexylcarbodiimide with subsequent alkaline ...
Phosphoproteins from calf-thymus nuclei: Studies on the method of isolation
(Elsevier, 1969-11-11)
Multiple frequency EPR studies on three forms of oxidized cytochrome c oxidase
(Elsevier, 1983-10-17)
Bovine heart mitochondrial cytochrome c oxidase (cytochrome aa3) (EC 1.9.3.1) has been demonstrated to occur in several forms when the redox centers in the protein are thought to be fully oxidized. We report here the results ...
Synthesis of metabolism-resistant substrates for the transport system for cationic amino acids; their stimulation of the release of insulin and glucagon, and of the urinary loss of amino acids related to cystinuria
(Elsevier, 1973-04-16)
Several amino acids have been synthesized as model transport substrates building on the piperidine and cyclohexane rings. Only when the distal N atom is part of an unambiguously cationic structure are these compounds ...
Soluble cytochrome b5 from human erythrocytes
(Elsevier, 1972-07-12)
1. A hemeprotein with properties similar to microsomal cytochrome b5 has been detected in the supernatant fraction of hemolysates of human, beef, and rabbit erythrocytes. A method has been developed for determining the ...
