Clinical development of vaccines based on adenovirus (Ad) vectors requires accurate techniques to determine vector doses including contents of infectious particles. For vectors derived from Ad virus of human serotype 5 content of infectious particles can readily be determined by plaque assays. Vaccine vectors based on alternative Ad serotypes such as those derived from chimpanzees or so-called rare serotype plaque poorly and titration by plaque assays underestimates the content of infectious particle by 50-100 fold. Here we describe a simple technique that was initially developed for titration of HAdV-5 vectors and that we modified for titration of Ad vectors from alternative serotypes.
