Transfer of small plasmid DNA fragments from polyacrylamide gels onto nitrocellulose paper
(Elsevier, 1983-10-15)
The incorporation into a 7% polyacrylamide gel of a nucleic acid-specific photochemical reagent 4,5',8-trimethylpsoralen at a concentration of 1 mg/dl of acrylamide solution improves both the sensitivity and the efficiency ...
Comparison of methods of analysis of polychlorinated biphenyls in oils
(Elsevier, 1983)
In order to standardize and validate methods for the analysis of polychlorinated biphenyls in transformer oil, waste oil, hydraulic fluid and capacitor oil in the concentration range 30-500 ppm, a study was performed which ...
Vibrational analysis of conformation in peptides, polypeptides, and proteins This is paper number 16 in a series of which Ref. 20 is paper 15.
(Wiley Subscription Services, Inc., A Wiley Company, 1983-01)
A vibrational force field for the polypeptide chain has been developed for normal-mode analysis of such molecules. It can reproduce observed frequencies of known structures to within about 5 cm −1 . We review the application ...
Binding of hydrophobic ligands to plant lectins: Titration with arylaminonaphthalenesulfonates
(Elsevier, 1983-07-15)
Binding of the Hydrophobic ligands 1,8-anilinonaphthalenesulfonic acid (ANS) and 2,6-toluidinylnaphthalenesulfonic acid (TNS) to a variety of plant lectins was studied by lectin-induced alteration of the fluorescence spectra ...
Isolation and characterization of a glycopeptide from human senescent erythrocytes
(Elsevier, 1983-08-16)
A glycopeptide (called "senescence-factor glycopeptide", SF-G) has been isolated from a tryptic digest of human erythrocytes by specific adsorption and elution from immobilized peanut lectin. SF-G was detectable in old but ...
Glucocorticoid receptor stabilization: Relative effects of molybdate ion on inactivation by alkaline phosphatase and phospholipase A2
(Elsevier, 1983-01)
Glucocorticoid receptors in cytosol preparations from rat liver or mouse L cells are inactivated by phospholipase A2 or calf intestine alkaline phosphatase. Molybdate ion, an inhibitor of a variety of phosphatase enzymes, ...
Iron and manganese superoxide dismutases
(Elsevier, 1983)
Fe and Mn SDs are enigmatic metalloproteins for several reasons: They are found in strict anaerobes as well as aerobes. In some cases the Fe and Mn ions appear to be interchangeable while in others they are not. In some ...
Thermophysics of metal alkanoates II. Heat capacities and thermodynamic properties of sodium propanoate
(Elsevier, 1983-07)
The heat capacity of sodium propanoate has been measured from 9 to 580 K by adiabatic calorimetry and considerable metastability noted between 60 and 215 K. Values at 298.15 K of Cp,m/R, Smo/R, "Hmo-Hmo(0)'/R, and ...
Separation of hemoglobin types by cation-exchange high-performance liquid chromatography,
(Elsevier, 1983-10-01)
The use of a recently developed cation-exchange HPLC packing material for the separation of hemoglobin types in human blood has been investigated. Adult and newborn hemolysates from normal individuals and from subjects ...
