Abstract: In order to compare the expression difference between AAV-ITR expression mini vector and its monomers in different parts of mice,the same copy number of AAV-ITR mini vector and pUC57-minivector-EGFP were separately transferred into the brain of mice. In addition,the same copy number of monomers of AAV-ITR mini vector and pUC57-minivector-EGFP were transferred into mouse skeletal muscle,and the number of residual molecules were compared in the different tissues at different periods. Analysis by florescence quantitative PCR,microscope observation,average optical density,and gray value showed that monomers of AAV-ITR mini vector in the same copy number had higher transfection efficiency and more stable than AAV-ITR mini vector and pUC57-minivector-EGFP. The comprehensive results suggest that the monomers of AAV-ITR mini vector present the feature of efficient,secure and stable expression,which may be expected to become a novel,secure,reliable,stable,and efficient vector in gene therapy.
