摘要: The present invention relates to improved methods and assays for the detection of adeno-associated virus (AAV) neutralizing antibodies in sera. The present invention provides safe, sensitive and high throughput neutralization assays for antibody detection. Specifically, the methods comprising incubating an AAV vector with dilutions of a serum sample to form a mixture; exposing AAV permissive cells to the mixture; measuring the amount or quantity of AAV permissive cells which have been transduced; and determining the AAV neutralizing antibody titer in the serum sample based on the measurement.
