Abstract

A colorimetric method has been developed for the detection of adeno-associated virus (AAV) infectious centers in cell culture monolayers. Due to its non-cytopathic nature, AAV has not been amenable to the traditional plaque assay, involving an agar overlay and cellular stains. As a result, an alternate method was required. The pseudo-plaque assay is based on enzyme-catalyzed color development after a fixed cell monolayer is probed with anti-AAV monoclonal antibodies. In spite of chemical fixation, expected to damage the viral genomes and particles, infectious particles can be recovered and amplified for the propagation of viral clones.
