Objective:To construct and identify a plasmid vector of short interfering RNA(siRNA)on pneumocystis carinii(PC) major surface glycoprotein(MSG)gene’s upstream conserved sequence(UCS).Methods:Short hairpin RNA(shRNA) oligonucleotide targeting PC MSG UCS gene which was chemically synthesized and inserted into RNAi-Ready plasmid vector pTZU6+1 after annealing.The recombinant plasmid
PC-UCS
transformed into E.coil.TOP10 and amplified
was digested by restriction endonucleases HindⅢand EcoRI 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
