Capillary Electrophoresis Separation Techniques and Mechanisms in Dilute Polymer Matrices
(WILEY‐VCH Verlag, 1995-02)
Capillary electrophoresis in ultradilute derivatized solutions is used to separate nucleic acid fragment mixtures. Pulsed field techniques are used to improve resolution. Protocols in which pulse parameters are varied ...
The -ills of Educational Reform
(Springer-Verlag; Springer-Verlag New York, Inc., 1998-02)
Many instructors have sincerely accepted problem solving and critical thinking as instructional objectives. This kind of language, especially notions of the liberal-arts values of taking college classes, is used in compelling ...
Genesis and solvus relations of submicroscopically intergrown paragonite and phengite in a blueschist from northern California
(Springer-Verlag, 1991-01)
Electron microbeam techniques have been used to examine submicroscopically intergrown paragonite, phengite and chlorite from the South Fork Mountain Schist of the Franciscan Terrane of northern California, which was subjected ...
A comparison of proteins and peptides as substrates for microsomal and solubilized oligosaccharyltransferase
(Elsevier, 1994-11)
A chemoenzymatic synthesis of homogeneous neoglycoproteins and glycopeptides was explored using oligosaccharyltransferase isolated from yeast. Neither the microsomal form nor the solubilized form of the enzyme catalyzed ...
Benzimidazole ribonucleosides: Observation of an unexpected nitration when performing non-aqueous diazotizations with t-butyl nitrite
(Elsevier, 1992-09)
Mild, non-acidic conditions used in the non-aqueous diazotization of a 2-aminobenzimidazole nucleoside with t-butyl nitrite gave an unexpected 4-nitrobenzimidazol-2-one nucleoside which was not formed when primary alkyl ...
Triple Junction Mobility: A Molecular Dynamics Study
(Kluwer Academic Publishers; Springer Science+Business Media, 1999-11)
We present a molecular dynamics simulation study of the migration of individual grain boundary triple junctions. The simulation cell was designed to achieve steady state migration. Observations of the triple junction angle ...
Thermodynamics of alkali alkanoates IX. Heat capacity and thermodynamic functions of lithium 2-methylpropanoate at temperatures from 7 K to 535 K
(Elsevier, 1993-10)
The heat capacity of lithium 2-methylpropanoate was measured by equilibrium adiabatic calorimetry at temperatures, T from 7 K up to 350 K and by d.s.c. from 330 K through melting to 535 K. A small diffuse hump was observed ...
Carboxylmethylation affects the proteolysis of myelin basic protein by Staphylococcus aureus V8 proteinase
(Elsevier, 1991-10-25)
Bovine myelin basic protein (MBP), charge isoform 1 (C1) was carboxylmethylated by the enzyme -aspartyl/-isoaspartyl protein methyltransferase (EC. 2.1.1.77) and the carboxylmethylated protein was subjected to proteolysis ...
Vibrational studies of the disulfide group in proteins. Part V. Correlation of SS stretch frequencies with the CCSS dihedral angle in known protein disulfide bridges
(Wiley Subscription Services, Inc., A Wiley Company, 1992-04)
Normal mode calculations have been done on 92 disulfide bridges in 25 known protein structures in order to correlate the SS stretch frequency with the CCSS dihedral angle. It is possible to classify the frequencies into ...
