SignaGen offers a comprehensive portfolio of pre-manufactured viral vectors designed for tightly regulated, inducible gene expression in mammalian systems. In parallel, we provide full-service custom vector engineering and production using adenoviral, adeno-associated viral (AAV), and lentiviral platforms to generate inducible expression constructs optimized for specific promoters, regulatory elements, and transgenes of interest. Our scientific support team delivers detailed vector maps, induction kinetics, and empirically guided dosing recommendations to suppress basal promoter activity and minimize off-target or background expression (“leakiness”). These measures enable high dynamic range, reproducible induction, and ensure experimental fidelity in studies requiring precise temporal and quantitative control of gene expression.
