The clone was used to investigate the AAV assembly process on the cellular level. The clone was used to immunoprecipitate capsid proteins from extracts of [35S]methionine-labeled HeLa cells infected with AAV-2 and adenovirus type 2. Immunofluorescence was preformed on AAV-2/adenovirus type 2-coinfected HeLa cells using this antibody (Wistuba et al, 1997; pmid:8995658). Epitope sequences on the capsid surface were identified by enzyme-linked immunoabsorbent assay using AAV-2 mutants and AAV serotypes, peptide scan, and peptide competition experiments. The clone neutralizes infection following receptor attachment by binding an epitope formed during AAV-2 capsid assembly. The antibody bound empty and full AAV-2 particles in an ELISA. In a neutralization assay, incubation of rAAV-2-GFP with A20, on HeLa cells prevented transgene expression. The clone reacted also with AAV-3 as shown by ELISA (Wobus et al, 2000; pmid:10982375). The structure for the complex AAV-2 with Fab fragment was determined by cryo-electron microscopy (McCraw et al, 2012; pmid:22682774).
