Sentence examples for radioactive systems from inspiring English sources

Due to the lower sensitivity of chemiluminescent detection compared with radioactive systems, an additional hybridization experiment was performed with cytotypes BB, which had been shown to possess lower amounts of satellite DNA, using 1 μg and additionally also 3 μg of genomic DNA.

Quantification is improving [ 15] and radioactive detection systems have a wide linear range, but the linearity of the widely used chemical systems today is not well defined.

There are separate classes of radioactive decay systems on which different isotopic dating methods are based; cosmogenic nuclides (e.g. C-14, tritium and Cl-36), the uranium/thorium-series disequilibria systems (e.g. the 230Th-232Th and 210Pb methods), long-lived systems (e.g. the U Pb, K Ar and Ar Ar methods), and radiation damage methods (e.g. thermoluminescence and fission track methods).

It was also unexpected because conventional radioactive assay systems commonly detect de novo RNA synthesis by the HCV-polymerase within minutes to hours.
