Table 2. The effect of D-labeling on the evolution of the C2D/C2H ratio.
After D-water labeling, different domains within the crypt demonstrate different degrees of D-labeling, providing an opportunity to assess the evolution of the C2D/C2H ratio as a function of sputtering depth. An analysis of unlabeled crypt (Figures 2,3) is provided as a reference (right columns). The mean ratio is provided for the first plateau (< 3.5*1016 Cs) and the second plateau.
