The ability of antibodies to block adenovirus infection of Hela cells or AAV2 infection of 84-31 (293 cells stably expressing Ad-E4) in vitro is analyzed utilizing Green Fluorescent Protein as a reporter*. For the assay, various dilutions of antibodies pre-incubated with moi of 100 for adenovirus and 1000 for AAV reporter viruses for 1 hour at 37°C, is added to 90% confluent cell cultures. Cells are incubated for 20 hours. Expression of GFP is quantitated by manually counting under a UV-microscope and LacZ by an automated luminometer. The neutralizing titer of antibody is calculated by the highest dilution of the sera where 50% of the cells are green. *or LacZ"
