RenNano™, a fully human heavy-chain antibody platform developed by Biocytogen Pharmaceuticals Co., Ltd., has been launched officially. RenNano™ joins RenMab™ and RenLite® as the newest member of the RenMice™ family. All three RenMice™ technologies from Biocytogen work together to speed up the search and development of entirely human monoclonal, bispecific/multispecific, and single-domain antibodies (sdAbs, or nanobodies).
Camels and sharks produce heavy-chain-only antibodies (HCAb), indicating their variable domains (VHH or sdAb) are functional without pairing with the light chain. Still, humans and mice produce antibodies that require heavy and light chain coupling to be effective. Because of their molecular weight and size, sdAbs can enter solid tumor tissues and breach the blood-brain barrier. Additionally, the sdAb's larger CDR3 region allows for detecting the otherwise concealed epitopes of GPCRs and other challenging targets.
Nanobodies offer their benefits, but it's challenging to use animals that naturally make HCAbs, like camels, in large numbers to create monoclonal antibodies due to their size, slow reproduction rate, and limited offspring supply. However, humanizing camelid antibody sequences for pharmaceutical use adds another layer of complexity and time to the drug development process.
Accordingly, Biocytogen modified the constant area of the entirely human RenMab™ model to create the RenNano™ Mouse, which is genetically modified to manufacture HCAbs. RenNano™ Mouse is one of the world's most comprehensive human antibody platforms due to the substitution of the mouse genes with the complete human heavy chain variable genes.
