[Cloning and expressing the E2 subunit of pyruvate dehydrogenase complex].
OBJECTIVE
To construct the expression vector of the pyruvate dehydrogenase complex E2 subunit gene (PDC-E2).


METHODS
The PDC-E2 gene was amplified from human lymphocytes with RT-PCR, and was cloned into pExSecI vector to induce the PDC-E2 expression. The products were identified with western blot and ELISA.


RESULTS
The expression vector pExSecI/PDC-E2 was successfully constructed. The products could be identified by the specific self-antibodies in the sera from the primary biliary cirrhosis patients.


CONCLUSIONS
High efficient expression vector of PDC-E2 lays the foundation for serum assay of primary biliary cirrhosis patients with prokaryotic expressing PDC-E2.
