Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional antibodies are used to target anti-CD19 scFv FMC63, then general immunotherapy applications can be pursued, but specificity and efficacy in binding to FMC63 are insufficient
Solution Approach 1:
The patent develops antigen binding molecules with specialized local properties optimized for binding to FMC63. The rabbit-derived antibodies and scFv fragments are engineered with specific variable regions that exhibit high affinity and specificity for FMC63, while maintaining appropriate Fc region properties for effector functions. This local optimization of binding characteristics resolves the contradiction between high specificity and broad applicability.
Solution Approach 2:
The invention employs systematic variation of key parameters including antibody isotype (IgG1, IgG2a, IgG2b, IgG4), binding affinity, and molecular format (full antibody, scFv, Fab). By changing these parameters, the patent creates a family of molecules with optimized properties for different applications while maintaining FMC63 specificity, thus resolving the contradiction between reliability and adaptability.
2Measurement precision
If rabbit-derived antigen binding molecules are developed for high specificity, then detection precision improves, but manufacturing complexity increases
Solution Approach 1:
The patent segments the antibody molecule into modular components including variable regions (VH, VL), constant regions (Fc), and linker sequences. This segmentation allows for standardized production of common elements while customizing only the variable regions for FMC63 binding, thereby reducing overall manufacturing complexity while maintaining high detection precision.
Solution Approach 2:
The invention creates universal building blocks such as standardized Fc regions and linker sequences that can be reused across multiple antibody variants. This universality simplifies manufacturing processes by reducing the number of unique components that require separate production and quality control, while still enabling high-precision detection through specialized variable regions.
