CLint estimates determined from fresh and cryopreserved dog and human hepatocytes Results are expressed as the mean CLint ± standard deviation from five human and six dog donors. Results not expressing a S.D. are from two donors only. The CLint determinations were carried out as described under Materials and Methods. The CLint estimates reported in Table 1 represent a different donor pool from the one reported in this table, which can result in different mean values for the same substrate.
