↵1-a Metabolite production in pmol/min/slice. Peak areas of other metabolites (6β-OH, 19-OH, 14α-OH, 16α-OH, 16β-OH, and androstenodione) were measured and maintained at 62 to 114%, 54 to 71%, and 73 to 117% fresh slices for liver 1, 2, and 3, respectively. Total peak area of metabolites formed (including androstenodione) was 97, 59, and 94% fresh slices, respectively.
