At SignaGen Laboratories, our High-Titer Adenovirus Production service delivers robust, research-grade adenoviral vectors optimized for efficient gene overexpression and adenovirus-mediated homology-directed repair (HDR) using the Ad.MAX platform. A key advantage of adenovirus-mediated donor integration is its ability to deliver large, intact donor DNA templates episomally at high copy number, enabling efficient nuclear availability of donor sequences without random genomic integration. This property allows the use of long homology arms and complex donor cassettes, which significantly improves precise HDR efficiency compared with size-restricted viral systems.

The Ad.MAX platform supports stable cloning and high-fidelity packaging of these large donor constructs while maintaining strong transgene expression and genetic integrity. Our workflow integrates precision vector design, sequence-verified cloning, and scalable high-titer production, followed by optimized purification to ensure consistency and purity. Each batch undergoes rigorous quality control, including physical titer determination, infectivity assays, and sterility testing.

With flexible production scales and rapid turnaround options, SignaGen provides an end-to-end adenovirus solution for high-level gene overexpression and efficient, precise donor integration in HDR-based genome editing studies.
