Stealth RNA Vector (SRV) can be produced in large quantities free from chromosomal integration, and is the one and only vector in the world that can stably express genes for a long period of time. SRV is latent for gene therapy that couldn’t be achieved with AAV or lentiviral vectors.
Regarding various virus vectors used in existing gene therapy which utilizing the characteristics of each vector has been developed. Tokiwa-Bio is developing gene therapy by utilizing the unique features of SRV.
