A support for affinity chromatography that covalently binds amino groups via a cleavable connector arm
(Elsevier, 1979-03)
The preparation of a new succinimidyl ester agarose derivative (SEPE-Agarose) is described. This agarose derivative can be used for covalently linking proteins and other ligands containing amino groups to agarose via phenyl ...
A reinvestigation of the vibrational spectroscopy of pentaphenylarsenic and pentaphenylantimony
(Elsevier, 1974-04)
The laser-Raman and infrared spectra of pentaphenylarsenic and pentaphenylantimony have been recorded both in the solid state and in solution. Structural conclusions for these molecules are based on an analysis of the ...
The numbers of chiral and achiral alkanes and monosubstituted alkanes
(Elsevier, 1976)
Whereas the theory for the enumeration of the optical isomers of the lakyl radicals and the alkanes has long been understood, this is not the case for the corresponding archiral isomers. We present for the first time ...
Heat capacity and thermodynamic properties of diamantane from 5 to 540 K
(Elsevier, 1978-10)
The heat capacity of diamantane, C14H20, has been measured by adiabatic calorimetry from 5 to 350 K. The heat capacity is generally sigmate except for a gradual thermal anomaly with a maximum at 35.7 K and an apparent ...
Cadmium and arsenite binding by N-dihydrolipoyl-aminoethoxydextran: A model study of enzyme dithiol criteria
(Elsevier, 1973)
We have observed the interaction of Cd2+, Zn2+, and AsO22- with a dithiol-substituted polymer (N-dihydrolipoyl aminoethoxy dextran). Cadmium binding results in an intense uv difference spectrum ([lambda]max = 240 nm). ...
Carbohydrate-binding properties of an immobilized [alpha]--galactopyranosyl-binding protein (lectin) from the seeds of Bandeiraea simplicifolia
(Elsevier, 1976-03)
The [alpha]--galactopyranosyl-binding lectin from Bandeiraea simplicifolia has been coupled to cyanogen bromide-activated Sepharose 4B. Using this immobilized system, we have been able to study the interaction of the lectin ...
Metal---metal multiple bonds : IV. The chemistry of bis(cyclopentadienyldicarbonyl-molybdenum) (Mo[triple bond]Mo)
(Elsevier, 1978-11-14)
The synthesis and chemistry of Cp2Mo2(CO)4 (I) a coplex containing a reaction Mo[triple bond]Mo triple bond, are described. The formation of I in refluxing xylene is shown to occur via odd-electron intermediates from ...
