Abstract:
Objective to construct the high titers rat Hes1 adenovirus expression vector (Ad-Hes1).Methods With the rat cDNA as a template,the Hes1 fragment was amplified by PCR,which constructed pShuttle-CMV-Hes1 shuttle plasmid by directly clone.Based on pShuttle-CMV-Hes1,pAdeno-Hes1 virus plasmid was constructed,pAdeno-Hes1 was transfected into 293 cells to package Ad-Hes1,virus titers were determined by modified TCID50.Hes1 was detected by Western blot after Ad-Hes1 infected with H9c2 myocardial cells.Results pShuttle-CMV-Hes1 shuttle plasmid and pAdeno-Hes1 plasmid were constructed successfully,with a general titer of 1.6 × 1011 PFU,Ad-Hes1 can be expressed in H9c2 myocardial cells,and its MOI value was 30.Conclusion Ad-Hes1 is successfully constructedand packaged,thus provide basis for further research on the protection effect of Hes1 on myocardium.
