https://doi.org/10.1007/BFb0093653d today many investigations into intermediary and other aspects of metabolism rely on these methods. Soon after the marriage of chromatography to the use of tracers, various instruments were constructed which were able simultaneously to locate the positions of radioactive compounds on paper chromato

Inertia. Basic Equations for the Interfaceed for the trapping of the C.O. for purposes of determining the radioactivity. We do not intend to review the literature on the subject. For a number of years our laboratory has been engaged in the study of .-aminobutyric acid and the enzyme which fauns it from L-glutamic acid, glutamic decarboxylas

Formulation within a Classical Contextstablished in many laboratories. A number of one- and two-dimensional scanning devices have been developed for purposes of determining quantitatively the C. radioactivity in amino acid spots on paper [.]. However the counting efficiency of these devices is low even when so-called 4. geometry is empl

Change in Reference Configurational scanning [.]. Direct counting of the thin-layer adsorbent [.] in a liquid scintillation system provides the simplest, most quantitative and most efficient means of counting weak-energy beta emitters of low-activity samples, since elution steps are not required and the maximal counting efficiency

Formulation within a Classical Contextechniques were developed for petroleum products they could not be transferred directly to lipid problems. For example, materials used for the construction of insulators which were suitable for hydrocarbons at 100°C, melted at 250°C; problems of condensation in gas-stream conduction tubes, which are

Inertia. Basic Equations for the Interface those of separation and those of identification of the intermediates. Within recent years, separation capabilities, exemplified by gas chromatography, have escalated far more rapidly than the corresponding capabilities for identification of the isolated fractions. The biochemist may be faced with a

Formulation within a Classical Context Full use of a specific label is achieved when procedures are also available which permit specific degradation of products and ultimate recovery of the isotope in a degradation product that pinpoints the exact location of the tagged atom.
