Use of Liquid-Scintillation Systems in Biological Studies

Liquid Scintillation Counting

discussed, and he points out that merely because a disease is found to be familial in incidence does not mean it is hereditarily transmitted; leprosy, for instance, was long held to be a hereditary disease, and a law was actually proposed in the Norwegian Parliament forbidding the marriage of lepers for that reason. It was only with the discovery of the leprosy bacillus by Hansen that the true ...

Nanoscintillation Systems for Aqueous-Based Liquid Scintillation Counting

Cooperativity in biological systems

Living organisms can sense and respond to external and internal stimuli. Response isdemonstrated in many forms including modulation of gene expression profiles, motility,secretion, cell death, etc. Nevertheless, all forms share a basic property: they depend on sensingsmall changes in the concentration of an effector molecule or subtle conformational changes ina protein and invoking the appropri...

Cocktails for Liquid Scintillation Counting

It is most important to assure 4 π−geometry in liquid scintillation counting for accurate results1. Usually this can be assured by dissolution of the sample in an appropriate cocktail. The cocktail does not only contain a solvent but also at least one scintillator and surfactants for aqueous samples because aqueous samples are completely insoluble in the pure organic solvents and scintillators....

Low Background Liquid Scintillation in Borexino

After a short introduction to solar neutrino physics, this paper describes the design concept and expected performance of the Borexino underground detector at Gran Sasso. Low background results from the Counting Test Facility, the rst phase of the Borexino project, are summarized.
