Example of MID sample standard deviation (A) Example of estimated mass isotopomer distribution (MID) of citrate from epithelial cells, as described in section 2.5.
M+i indicate the fractional abundance of the i:th mass isotopomer. (B) Difference between the assumed magnitude of the standard deviations and the measured magnitudes.
