Biocytogen's SUPCE™-Based

Fully Human Antibody Discovery Platforms

Leveraging its cutting-edge gene-editing expertise, Biocytogen has developed the proprietary Size-Unlimited and Precise Chromosome Engineering (SUPCE™) technology. Based on this innovative technique, Biocytogen employs a large-fragment in situ replacement strategy to seamlessly substitute human antibody gene sequences while preserving the mouse Fc region. This ensures the production of fully human antibodies while supporting normal immune system development, laying the foundation of Biocytogen's RenMice® antibody discovery platforms.

The RenMice® family—featuring RenMab™, RenLite®, RenNano®, RenTCRmimic™, and RenMice® KO—offers unparalleled versatility in antibody discovery:
