About Us

cq9电子平台网站 (Correctseq) aims to use our innovative base editing technology to help people with severe diseases.


We have developed multiple base editing systems and our base editors offer significant advantages in controlling off-target effects and improving in vivo editing efficiency. Our base editing studies were published in high-profile scientific journals including Nature Biotechnology, Nature Cell Biology, Nature Structural & Molecular Biology, Cell Research and Cell Reports.


Our goal is to discover, develop, manufacture, and commercialize curative genetic medicines for various diseases. Multiple pipelines for genetic diseases, cancer immunotherapy, metabolic diseases, and infectious diseases are well underway. We have set up R&D and manufacturing centers in Shanghai, as well as the regulatory and clinical center in China Central Place, Beijing. Our world-class R&D laboratory, CMC process development laboratory and cGMP manufacturing facility guarantee the rapid translation and application of our innovative research.


We focus on biotechnology innovation, research and development and are committed to providing efficient, reliable and safe solution for unmet medical needs.
