  • 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.

    Advantages

    1. Two independent intellectual property rights, comprehensively matching the needs of the project:circPrecise® by Group I intron self-splicing,circPure® by T4 Rnl2;

    2. Unique sequence design approach,circularization efficiency>90%:using modular translation element screening and secondary structure prediction of IRES and CDS interaction, the translation efficiency is greatly improved;

    3. Robust amplification production process,mass production scale up:flexible IVT- circularization scale from μg to g grade for different templates;

    4. Various purification strategies,purity>95%:analyze impurity components and concentration to customize a personalized chromatographic purification strategy;

    5. Common LNP encapsulation platform,efficiency>95%:self-developed liposome screening, platform for different formulations;

    6. Multi-dimensional QC platform:develop analytical methods to match the needs of project, and meet the QC evaluation of each stage;

    7. Efficient raw material synthesis platform to reduce production costs significantly.
