Control of acetylcholine receptor mobility and distribution in cultured muscle membranes. A fluorescence study
(Elsevier, 1978-07-20)
The molecular control of the distribution and motion of acetylcholine receptors in the plasma membrane of developing rat myotubes in primary cell culture was investigated by fluorescence techniques. Acetylcholine receptors ...
The heat capacity and thermodynamic functions of crystalline and liquid triptycene
(Elsevier, 1970-03)
The heat capacity of the propeller-shaped molecule triptycene (C20H14) was measured from 5 to 550 K. No anomaly other than melting was apparent, and the sample (99.999 per cent pure, as determined by analysis of the melting ...
Stimulation of uterine nonhistone protein phosphorylation and nuclear protein kinase activity by estradiol-17[beta]
(Elsevier, 1976-06-18)
Changes in the phosphorylation of nonhistone chromosomal proteins have been followed in rat uterus stimulated by 17[beta]-estradiol. Isolated uteri were found to incorporate 32Pi into nonhistone proteins via an endogenous ...
Thermodynamics of the lanthanide halides I. Heat capacities and Schottky anomalies of LaCl3, PrCl3, and NdCl3 from 5 to 350 K
(Elsevier, 1976-12)
The heat capacities of LaCl3, PrCl3, and NdCl3 have been measured from 5 to 350 K by adiabatic calorimetry. No co-operative thermal anomalies were seen in the temperature range investigated but substantial magnetic ...
D-Glucuronic acid: A non-inhibitor of the concanavalin A system
(Elsevier, 1972-06-22)
D-Glucuronic acid is demonstrated not to inhibit the concanavalin A system; previous claims to the contrary are shown to be due to a pH effect. Concanavalin A does not precipitate biopolymers containing nonreducing, terminal ...
Influence of the gradient in orientation on the compressive elastic modulus and yield strength of oriented polypropylene
(Elsevier, 1979-10)
The deliberate orientation of polymers is sometimes induced by the propagation of a stable neck due to uniaxial tensile loading; this has been called cold drawing. This highly anisotropic material is often used for various ...
Joining of simian virus 40 DNA molecules at endonuclease R Eco RI sites by polynucleotide ligase and analysis of the products by agarose gel electrophoresis
(Elsevier, 1976-07-02)
DNA molecules cut with endonuclease R Eco RI can be joined at Eco RI cleavage sites by incubation with polynucleotide ligase. In order to define the optimum conditions for this reaction, linear Simian Virus 40 DNA molecules ...
Tritium exchange reactions catalyzed by 2-oxo-4-hydroxyglutarate aldolase from Escherichia coli K-12
(Elsevier, 1979-05-10)
Tritiated water and tritiated substrates have been used to study exchange reactions catalyzed by Escherichia coli 2-oxo-4-hydroxyglutarate aldolase (4-hydroxy-2-oxoglutarate glyoxylate-lyase, EC 4.1.3.16, 2-oxo-4-hydroxyglutarate ...
