This paper describes the adaptation and evaluation of an error-compensating method for kinetic determinations of DNA. A single size DNA is used for the initial study. The experimental procedures involve gel electrophoresis with ethidium bromide staining followed by DNase treatment of the agarose gel containing the single DNA band. The time-dependent decrease in fluorescence of the DNA band is monitored...
An analytical method for the simultaneous determination of some trace elements (Au, Fe, Mg, Li, Sr, Zn) in human serum by inductively coupled plasma atomic emission spectrometry (ICP-AES) with flow injection is described. Physical interference caused by the change of sample viscosity is discussed. When 100 μl of serum was injected, the relevant recoveries of > 99% for Li, > 98% for Cu and...
