At SignaGen, AAV vector design for transgene overexpression and HDR donors is performed entirely in-house using advanced, software-driven platforms to ensure accuracy, consistency, and efficiency from the earliest stages of development. The design of AAV cis vectors and HDR donors is guided by the origin and nature of the gene of interest (GOI), whether derived from an end-user–provided plasmid or a synthesized fragment produced at SignaGen. Our in silico workflow enables precise definition of homology arms, edit junctions, and protective silent mutations for HDR, while simultaneously optimizing promoters, coding sequences, regulatory elements, and capsid variants for tissue-specific or ubiquitous expression.

Through comprehensive sequence validation and predictive modeling, we minimize design errors, ensure compliance with AAV packaging constraints, and maximize functional performance in downstream cloning and production. This integrated design approach delivers reliable, reproducible, and high-quality AAV vectors for gene overexpression and precise genome editing applications.
