In vitro ligation reducing one step compared to pAdEasy system, Adeno-X adenoviral system 3 uses expression cassette to directly clone onto pAd backbone eliminating subcloning in shuttle vector. Integration into the host genome is a random unpredictable event, hence depending on the site of protpcol, cellular function may be disturbed due to genetic disruption, concerns for insertional mutagenesis causing activation of oncogenes have also been observed.

Example of adenoviral mediated gene delivery in vivo using Ad-LacZ as control to determine expression levels of recombinant adenovirus mediated target gene expression. Suitable for both in vitro including primary cells and in vivo use. Methods for construction of adenovirus vectors.

A helper-dependent adenovirus vector system: Best suited for in vitro use including primary cells, quick testing of a target cells, quick testing of a target before committing to transgenic mouse model. Evolution of model systems for homologous recombination: It is used for 1 gene therapy [ 1011 ] ; 2 molecular tool to study gene expression, both in vitro and in vivo expression in difficult-to-transduce cell types and tissues [ 12 ], for example, retrograde introduction of optogenetic channelrhodopsin 2 [ 13 ] or introduction of targeted mutagenesis in combination with gene-editing tools such as CRISPR [ 14 ] ; 3 the production of high levels of recombinant, potentially therapeutic proteins; and 4 in vivo adeaxy [ 15 ], for example, chimpanzee adenovirus vector Ebola vaccine adeasu 16 ].

Hence, the most commonly used adenoviral vectors are derived from human adenovirus serotypes 2 and 5 for in vitro and in vivo gene delivery [ 8 ]. We have developed an approach that simplifies the generation and production of such viruses called the AdEasy system.
