METHOD FOR CHARACTERISING THE ORIGIN AND/OR CONDITION OF DISEASED OR HEALTHY CELLS AND USES THEREOF IN BIOLOGY

摘要

The invention relates to a method for characterising the origin and/or condition of diseased or healthy cells, characterised in that it includes the measurement of isotopic variations in a natural abundance of elements of cells, the contents of which are modified in a situation of disease, using an isotope-ratio mass spectrometer (abbreviated as IRMS), advantageously using an elemental analyser coupled with an isotope-ratio mass spectrometer (abbreviated as EA-IRMS).
