The helper-dependent adenovirus (HDAd) is a recently developed adenovirus-based vector with an improved safety profile and long-term transgene expression. In this unit, a basic procedure for HDAd production using the Cre-loxP system is presented. Amplification and large-scale production of the vector can be done in both adherent and suspension cell culture systems. Included are protocols for Southern blot analysis to monitor vector amplification, slot blot assay to determine the infectious titer of the purified HDAd, and real-time PCR to detect helper virus contamination in the preparation.
