Long RNA, like mRNA, self-amplifying mRNA (saRNA) and circular mRNA (circRNA), have been widely used in the study of gene or protein functions. Meanwhile, they are popular in the development of prophylactic and therapeutic biologics. Relied on our powerful and proprietary RNASci platform, Yaohai Bio-Pharma provides catalog RNA products as well as bespoke in vitro transcription (IVT) RNA synthesis services. We have established a complete set of mRNA/saRNA/circRNA synthesis technologies to provide highly pure long RNAs, such as sequence design and optimization, IVT, circularization, purification, and LNP encapsulation. All products are released under stringent quality control standards.
