De Novo Isolation of an Antigen-Binding Antibody by Targeted CDR-H3 Diversification of a Germline-Derived Scaffold in a Site-Specifically Integrated Mammalian Display Platform: A Proof-of-Principle Study
Background/Objectives: Mammalian display enables direct screening of full-length IgG antibodies, but genetically controlled library construction remains technically demanding. Here, we developed a mammalian display platform in which a target-naïve ΔDH antibody scaffold is first established at a defined human artificial...
