Several normalization techniques have been used to minimize effects of this high within-treatment endogenous variation.
High endogenous variation within a condition can obscure between-condition changes.
If endogenous variation causes all compounds to vary as a simple multiple of the TA, then expressing each compound amount as a proportion of the TA for the sample is an unbiased estimator of relative abundances (RA).
