Effects of anharmonicity of molecular vibrations on the diffraction of electrons : Part III. Predictive models
(Elsevier, 1980-04)
It has long been known how to relate anharmonic vibrational distribution functions to scattered electron intensities when deriving molecular parameters from gas-phase electron diffraction patterns. What has been lacking ...
Properties of yeast pyruvate decarboxylase and their modification by proteolytic enzymes : I. Stability of decarboxylases from wild-type and mutant strains
(Elsevier, 1968)
High concentrations of inorganic phosphate and ammonium sulfate stabilize yeast pyruvate decarboxylase to heating at 60 [deg] for long periods of time in the presence of TPP and Mg+. When heated at 60 [deg] in phosphate ...
MoFe Cofactor of nitrogenase: Extraction, purification, and characterization
(Elsevier, 1989-08)
Use of Cyclodextrin-Cholesterol Complex as a Primary Standard in Cholesterol Analysis
(Elsevier, 1993-06)
Cholesterol is an analyte commonly measured in various biological fluids. Enzymic procedures have virtually replaced the chemical methods for cholesterol determinations. Standardization of cholesterol assays often involve ...
Nuclear phosphoproteins : I. Isolation and characterization of a phosphoprotein fraction from calf thymus nuclei
(Elsevier, 1969-02-04)
A phosphoprotein fraction has been isolated from calf thymus nuclei which contains about 1.3% alkali-labile phosphorus by wt. The enzymatic reaction in which serine and threonine residues in the protein are phosphorylated ...
Estimation of micromixing parameters from tracer concentration fluctuation measurements
(Elsevier, 1989)
A method of micromixing parameter estimation is proposed which is convenient and applicable to a wide variety of models. One conducts a typical tracer reponse test, except that in addition to the (time-averaged) mean tracer ...
Micro method for determination of borohydride with NAD+
(Elsevier, 1973-08)
A spectrophotometric method for the determination of borohydride is described. It involves the reduction of NAD+ to a number of isomeric forms of NADH by borohydride. In the standard assay procedure herewith presented, ...
