Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional antibodies are used for Nectin-4 detection, then general cell surface protein detection is possible, but specific detection and assessment of Nectin-4 expression cannot be achieved
Solution Approach 1:
The patent develops antibodies with specific binding properties tailored for Nectin-4 detection. The antibodies are engineered to recognize specific epitopes on Nectin-4, providing localized and specific detection capability rather than general cell surface protein detection. This enables precise measurement of Nectin-4 expression levels in biological samples.
2Measurement precision
If non-specific antibodies are used, then general immunostaining can be performed, but precise detection of Nectin-4 expression levels is not achieved
Solution Approach 1:
The patent introduces specific Nectin-4 binding antibodies as intermediary reagents that mediate between the detection system and Nectin-4 target. These antibodies serve as specific mediators that enable precise detection of Nectin-4 expression levels through standard immunodetection methods, including IHC staining and Western blotting, without requiring complex assay modifications.
3Measurement precision
If antibodies with low specificity are used, then broad protein detection is possible, but assessment of Nectin-4 in cancerous and normal cells cannot be differentiated
Solution Approach 1:
The patent employs antibodies with optimized binding parameters for Nectin-4 detection. By selecting and characterizing antibodies with specific affinity and specificity parameters for Nectin-4, the invention enables differentiation of Nectin-4 expression patterns between cancerous and normal cells. The antibodies are validated to provide clear distinction of expression levels across different cell types.
