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...
متن کاملIndustrial 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...
متن کاملA 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...

متن کاملA New Instrument for Obtaining Indicator Dilution Curves Using a Radioactive Tracer, I-125.
The use of indicator dilution curves has now become established as a routine procedure in studies of the circulation. Dyes are the commonly used indicators and the time concentration curve is obtained by intermittent sampling or by a continuous technique with an indwelling needle at a suitable sampling site. More recently radio-iodinated human serum albumin (1125HSA) has been successfully used ...
