Table 1 SW480 intracellular tocopherol concentrations (pmoles/well) after 24 hour treatments with 5 or 10 μM tocopherols as determined by HPLC analysis. The result is an average of three trials and the Standard Error of the Mean (SEM) is reported. γ-Tocopherol incorporates into the SW 480 cells at levels up to 20-fold that of α-tocopherol at the same treatment concentration.
