  • Product Introduction

  • With greater stability attributed to its unique closed-loop structure, circRNA is an ideal platform for the development of next-generation gene therapy as an effective alternative to linear mRNA. Geneseed has original circularization patent technology, which can realize high efficiency circularization of RNA, and the prepared circRNA has high integrity and purity, as well as strong translation and expression ability, which can be used in many fields such as cell transfection, animal experiments, and drug efficacy evaluation.
