  • circRNA CRDMO Service


    Circular RNA, with greater stability attributed to its unique closed-loop structure, is an ideal platform for the development of next-generation gene therapy as an effective alternative to linear mRNA. Geneseed has been focusing on circRNA for more than 10 years and has profound technology accumulation. Geneseed has two patented RNA circularization strategies: Group Ⅰintron self-splicing and T4 Rnl2 method. We have established platforms for sequence design, process development, analytical method development, scale production, QC, raw material preparation, etc., which can provide biopharma with CRDMO services in the whole process from early R&D to commercial production.
