Western blot analysis of Cyp1a1, POR, Cyb5 and Cyb5R in the pooled microsomal fractions of untreated (lanes 1–3) and BaP-treated (lanes 4–6) WT, HRN and HBRN mice. Gapdh protein expression was used as a loading control. Representative images of the Western blotting are shown, and at least duplicate analysis was performed in separate experiments
