A specific radioimmunoassay for androstenedione with reduced bridge-binding
(Elsevier, 1984-09)
Antibody used in a steroid radioimmunoassay raised against a steroid hapten-carrier protein conjugate may recognize both the hapten and the chemical bridge to the protein. Use of the same bridge in the radioisotopic label ...
Thermophysics of metal alkanoates IV. Heat capacities and thermodynamic properties of potassium 2-methylpropanoate
(Elsevier, 1984-02)
The molar heat capacity of potassium 2-methylpropanoate, (CH3)2CHCO2K, has been measured between 8 and 350 K by adiabatic calorimetry, and found to be normal. The corresponding thermodynamic functions have been calculated. ...
Metalloporphyrins in Oxidative Catalysis. Oxygen Transfer Reactions of Oxochromium Porphyrins
(WILEY‐VCH Verlag, 1985)
The oxidation of chloro‐5‐10,15,20‐tetramesitylporphyrinotoiron(III) with peroxyacids affords a reactive oxoiron(IV)‐porphyrin cation radical species 2. The characterization of 2 and its oxochromium analogs 3, 4 and 5 are ...
On the dynamic structure factor, S(q,[omega]), of polymers in dilute solution
(Elsevier, 1981-08)
In principle, interpretation of dynamic scattering experiments requires theoretical calculation of either intermediate scattering functions S(q,t) or dynamic structure factors S(q,[omega]). Although dynamic scattering ...
Effect of gravity on Brownian flocculation
(Elsevier, 1984-09)
In previous analyses of simultaneous Brownian and gravity-induced flocculation, it has been assumed that each mechanism contributes independently to the total flocculation rate. In this paper the rigorous problem of coupled ...
Stereochemistry in the cyclization of -azidophenylalkenes to indoles
(Elsevier, 1983)
- and --azidostilbene, -azido-[beta]-methylstilbene, and ()--azido[beta]-deuteriostyrene give indoles on thermolysis by a mechanism involving attack by a nitrene directly on the [beta] carbon atom, and not by insertion.
Transition dipole interaction in polypeptides: Ab initio calculation of transition dipole parameters
(Elsevier, 1984-06-15)
Ab initio calculations of dipole moment derivatives of a model system of N-methylacetamide hydrogen-bonded to two formamide molecules give values for amide I and amide II transition dipole moments consistent with those ...
Human neutrophils permeabilized with digitonin respond with lysosomal enzyme release when exposed to micromolar levels of free calcium
(Elsevier, 1986-04-08)
We have recently reported that human neutrophils can be permeabilized with the cholesterol complexing agent saponin and that these cells can be induced to secrete the granule enzyme lysozyme in response to micromolar levels ...
A structural comparison of the A and B subunits of Griffonia simplicifolia I isolectins
(Elsevier, 1984-02-15)
A structural comparison between the A and B subunits of the five tetrameric Griffonia simplicifolia I isolectins (A4, A3B, A2B2, AB3, B4) was undertaken to determine the extent of homology between the subunits. The first ...
Antagonism of the discriminative effects of ethylketazocine, cyclazocine, and nalorphine in macaques
(Springer-Verlag, 1984-09)
dl -Ethylketazocine (EKC, 0.01 mg/kg) and saline were established as discriminative stimuli for food-maintained responding in macaque monkeys. Thirty consecutive presses on a right or left lever were reinforced with food, ...
