Radioactive Tracer Techniques in Biology

Radioactive tracer techniques in the sequencing of glycoprotein oligosaccharides.

Complete sequencing of the oligosaccharide units of glycoproteins can be performed by conventional physical techniques if nanomole quantities of pure molecules are available. However, isolation of sufficient quantities of a glycoprotein may not be technically feasible (e.g., the analysis of biosynthetic intermediates, or rare molecules). Alternatively, partial structural analyses may answer the...

Radioactive Tracers in Biology

Everybody talks about the atom, but few have more than a Sunday supplement knowledge of the simpler aspects of nuclear phenomena. The author, M.D. and Ph.D., and a member of the staff at Brookhaven, treats the story of the atom from its earliest historical conceptions to its possibilities in future war and peace. The style is of the simplest; no previous familiarity with mathematics or physics ...

Industrial Flotation Process Modelling : Rtd Measurement by Radioactive Tracer Technique

The residence time of liquid and solid was determined in flotation banks of mechanical cells and flotation columns at Salvador Division, Codelco-Chile. The estimation was developed from residence time distribution (RTD) measurements using radioactive tracers. Results allowed the estimation of effective pulp volumes in flotation banks and columns. It was found that industrial flotation banks are...

A Tracer Study of Iron Metabolism with Radioactive Iron

The metabolism of iron is one of the most important subjects in the field of mineral metabolism. ,There have been numerous investigations of its problems, but until recently they have been seriously limited by the methods of study available. The production of radioactive isotopes of iron (1, 2) provided a new research tool which has proved of great value in the investigation of this field. Iron...
