What makes SignaGen Laboratories different
Custom viral vector production
SignaGen designs and packages recombinant AAV, lentiviral, and adenoviral vectors to customer specifications. Services cover cloning, packaging, purification, and titer determination for in vitro and in vivo applications.
In vivo–grade quality
Vectors are available at high, guaranteed titers suitable for animal studies. SignaGen states pre-made AAVs at >1 × 10¹³ VG/mL, lentiviruses at >1 × 10⁹ TU/mL (RCL-free), and adenoviruses at >1 × 10¹⁰ PFU/mL (RCA-free).
Catalog and custom options
Researchers can order ready-to-use pre-made viral vectors and reporter constructs, or commission fully custom packaging. Multiple AAV serotypes, including AAV-DJ and Retrograde, support neuroscience, gene editing, and gene therapy research.
