Empty AAV2 capsids lacking the transgene of interest cause unwanted immune response without providing the therapeutic benefit of the transgene. Alongside DNA and infectious titer, determination of the capsid titer is crucial for validating the efficacy and safety of your AAV gene therapy. Our titration kit detects full and empty AAV2 capsids.

The AAV2 titration ELISA kit uses sandwich ELISA to determine the titer of AAV2 capsids in the test sample. The capture AAV2 monoclonal antibody is pre-coated and treated on a 96-well reaction plate. AAV2 standard or sample is added to the pre-coated plate and specifically binds to the capture antibody. The biotinylated detection AAV2 antibody is then added to the plate to bind the immune complex. Next, the streptavidin HRP conjugate is added to react with the biotin molecules. The addition of TMB results in color changes and the amplitude of the color change is proportional to the amount of AAV2 capsids that specifically bind to the plate. The reaction is stopped with the addition of stop solution and the absorbance is measured at 450nm. The sample AAV2 capsid titer is calculated from the AAV2 standards titration curve.
