Improved high-performance liquid chromatographic assay for the quantification of 5-bromo-2'-deoxyuridine and 5-bromouracil in plasma
(Elsevier, 1988)
A sensitive and specific procedure using high-performance liquid chromatography (HPLC) was developed for the quantification of 5-bromo-2'-deoxyuridine (BUdR) and 5-bromouracil (BU) in plasma. BUdR and BU were first extracted ...
FeAs: Heat capacity, enthalpy increments, other thermodynamic properties from 5 to 1350 K, and magnetic transition
(Elsevier, 1989-04)
The heat capacity of iron monoarsenide has been determined by adiabatic calorimetry from 5 to 1030 K and by drop calorimetry relative to 298.15 K over the range 875 to 1350 K. A small [lambda]-type transition is observed ...
Two-dimensional peptide mapping by reversed-phase column chromatography, applied to the sequence determination of cytochrome c from the wild type and a mutant of the butterfly, pieris brassicae
(Elsevier, 1983-08-26)
Two-dimensional peptide mapping has been very effective in the characterization of protein digests, particularly for the detection of small structural differences between homologous proteins. The classical thin-layer ...
[beta]-Endorphin suppression of acute morphine abstinence in morphine dependent monkeys: Effective given intraventricularly but ineffective given intravenously
(Elsevier, 1985-07)
Six female adult monkeys were made dependent upon morphine sulfate and were implanted with a chronic indwelling needle in the lateral ventricle of the brain for sterile intraventricular injections. Both [beta]-endorphin ...
Prodynorphin peptide immunocytochemistry in rhesus monkey brain
(Elsevier, 1985)
The present study describes the immunocytochemical distribution of peptides derived from the prodynorphin precursor in the brain of the rhesus monkey (Macaca mulatta). Animals were treated with colchicine (intracerebrove ...
Evidence that removal of an endogenous metal that stabilizes the untransformed glucocorticoid receptor in cytosol allows ligand-independent receptor transformation
(Elsevier, 1989)
Cytosol preparations contain an endogenous heat-stable factor which stabilizes the glucocorticoid receptor in its untransformed, non DNA-binding form. Elution of a partially purified preparation of this stabilizing factor ...
Synthesis of [alpha]- and [beta]-glycosides containing spin labels, as probes for studies of carbohydrate-protein interaction
(Elsevier, 1981-03-02)
Nitroxide spin-labeled [alpha]--glycopyranosides were synthesized in good yield and in a highly stereoselective manner by reaction of per-O-benzyl-[alpha]--glycopyranosyl bromides with 2,2,6,6-tetramethyl-4-piperidinol ...
Analysis of sperm antigens by sodium dodecyl sulfate gel/protein blot radioimmunobinding method
(Elsevier, 1982-06)
A radioimmunobinding method based on the blotting of renatured proteins from sodium dodecyl sulfate gels on to nitrocellulose filter papers was developed to analyze the sperm antigens that elicit serum anti-sperm antibodies. ...
Determination of the dead time of a stopped-flow fluorometer
(Elsevier, 1989-09)
This investigation was carried out to develop a convenient alternative method for examining the performance and determining the dead time of a stopped-flow fluorometer. We examined the kinetics for the formation of the ...
Crossed immunoelectrophoresis from sodium dodecyl sulfate-polyacrylamide gels after fixation and staining and without nonionic detergent intermediate layers
(Elsevier, 1981-09-01)
A modified method is described for crossed immunoelectrophoresis in which the first-dimension separation has been carried out by sodium dodecyl sulfate-polyacrylamide gel electrophoresis. The described method does not ...
