title: [Cloning and expression of new genotype of CYP2C9 from Chinese Han in Escherichia coli].
abstract: In this study, we successfully expanded a full length gene encoding the monooxygenase eytochrome P450 2C9 gene from human liver of Chinese Han by RT-PCR. Our findings indicated that except G-->T mutation at the 190th nucleotide site, the other nucleotide sequences are completely consistent with CYP2C9 (NM017460) in GenBank. The SDS-PAGE and Western-Blot analysis showed that the CYP 2C9 gene was successfully expressed in the host cell E. coli BL21 (DE3). Our current study lays the foundation for the evaluation of pre-clinical drug metabolism and safety in the future.
