-----英文摘要:---------------------------------------------------------------------------------------

Objective: To optimize and preliminarily validate a method for genome titer determination of recombinant adeno-associated virus type 9(rAAV-9) with the aim of improving the precision of test results.Methods: The method of virus dissociation was optimized by comparing the effect of SDS and EDTA,as well as SDS at different concentrations;an appropriate reference standard was selected by comparing the test results using plasmid or virus as the reference standard;an appropriate statistical method was selected by comparing the results of parallel line method and traditional single point method.Results: The results showed that the dissociation effect of SDS was significantly better than that of EDTA,and the effect of SDS was the best when its final concentration was 0.1%.The results of assay using virus as reference standard and parallel line method as statistical method showed the lowest variability (RSD of 13.7%),which was better than the assay using plasmid as reference standard (RSD of 35.9%) and single point method as statistical method (RSD of 23.1%).Conclusion: The optimized method is superior to the traditional method for genome titer determination of recombinant AAV and can be applied to the quality control of recombinant AAV-9 gene therapy products.
