Objective:To construct and identify a plasmid vector of short interfering RNA(siRNA) on pneumocystis carinii (PC) thymidylate synthase. Methods: Short hairpin RNA oligonucleotides of thymidylate synthase were chemically synthesized and inserted into plasmid vector pTZU6+1 after annealing. The recombinant plasmid
pPC-TS
transformed into E. coil. TOP10 and amplified
was digested by restriction endonucleases Hind Ⅲ and EcoR Ⅰ and identified by gel electrophoresis and DNA sequencing. Results: Gel electrophoresis and DNA sequencing showed that the recombinant plasmid containing the correct and full shRNA oligonucleotide. Conclusion:The siRNA plasmid
