The use of silica gel impregnated glass fiber sheets in plasma estriol assays
(Elsevier, 1970)
The fluorimetric quantitation of nanogram amounts of estriol extracted from plasma is sometimes impaired by impurities which interfere with fluorescence. Instant thin-layer chromatography on silica gel impregnated glass ...
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 ...
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)-[[ ...
