Excess 14C in individual FFE fractions. The baseline (35.0 amol) is composed of SDS from dialysis and tributyrin carrier. Dialysis produces a uniform baseline across all fractions. The 14C limit of quantitation (LOQ) is the sum of the baseline, 3x the uncertainty in the baseline (4.2 amol), and the maximum amount of adducted protein in a sample (1.0 amol).
