Vibrational analysis of crystalline diketopiperazine--II. Normal mode calculations
(Elsevier, 1984)
Based on our Raman and i.r. [1] data and assignments for DKP and five of its isotopic derivatives, we have refined an intramolecular force field in a non-redundant basis. This analysis shows that the cis peptide group may ...
Engineering Specific Cross‐Links in Nucleic Acids Using Glycol Linkers
(Wiley Periodicals, Inc., 2000-02)
One of the most convenient methods for generating oligonucleotides possessing intra‐ or interstrand cross‐links is through incorporation of oligoethylene glycol bridges by solid‐phase synthesis. The reagents are commercially ...
Proteomics FASTA Archive and Reference Resource
(WILEY-VCH Verlag, 2008-05)
A FASTA file archive and reference resource has been added to ProteomeCommons.org. Motivation for this new functionality derives from two primary sources. The first is the recent FASTA standardization work done by the Human ...
A polarographic method for following the rates of cholinesterase-catalyzed hydrolyses of acetylthiocholine
(Elsevier, 1965-08)
A rapid and simple polarographic method for following the rates of the cholinesterase-catalyzed hydrolysis of acetylthiocholine and the rates of inhibition of this hydrolysis is described. This method has the advantage ...
Transtubular bioreactor: A perfusion device for mammalian cell cultivation
(Kluwer Academic Publishers; Science & Technology Letters ; Springer Science+Business Media, 1989-01)
A transtubular mammalian cell perfusion chamber has been developed that allows separate delivery and control of medium and gas flow to the cells. The hydrodynamic and mass transfer characteristics of the reactor are studied ...
The effects of chlorpromazine on psychomotor stimulant self-administration in the Rhesus monkey
(Springer-Verlag, 1972-06)
The effects of acute and chronic chlorpromazine treatment on psychomotor stimulant self-administration behavior in the Rhesus monkey were determined. Chlorpromazine treatment significantly increased the frequency of ...
Interaction of five -mannose-specific lectins with a series of synthetic branched trisaccharides
(Elsevier, 1991-06-25)
The interaction of a series of synthetic, branched trisaccharides with five -mannose-specific lectins was studied by precipitation-inhibition assay. The branched methyl [alpha]--mannotrioside, [alpha]--Manp-(1-->3)-[[ ...
Boron-modified polysilylcarbodi-imides as precursors for Si–B–C–N ceramics: Synthesis, plastic-forming and high-temperature behavior
(John Wiley & Sons, Ltd., 1998-10)
The synthesis, by two different reaction pathways, of boron-modified polysilylcarbodi-imides of general type {B[C 2 H 4 Si(R)NCN] 3 } n (R 14=singly bonded organic ligand) and the plastic-forming and the thermal behavior ...
