Engineering Contradiction Analysis
1Productivity
If traditional experimental methods are used to characterize antibody binding on peptide arrays, then binding properties can be measured, but the process is costly, low-throughput, and lacks scalability
Solution Approach 1:
The patent creates a computational copy (in silico array) that mirrors the physical peptide array. This virtual array processes binding data through algorithms to predict antibody interactions, enabling high-throughput characterization without the cost and scalability limitations of physical experimentation while maintaining measurement precision through rigorous computational modeling
Solution Approach 2:
The patent replaces the mechanical/experimental binding assay system with a computational simulation system. Instead of physically measuring antibody binding to peptides on a chip, the system uses algorithms to process binding data and predict interactions, substituting physical measurement with computational analysis to achieve high throughput and scalability
2Reliability
If traditional binding analysis methods are used, then specific binding interactions can be detected, but reproducibility issues arise and the process is not scalable
Solution Approach 1:
The patent creates a reproducible computational model that can be consistently applied across different datasets and experiments. The in silico array and associated algorithms provide a standardized framework for analyzing binding data, eliminating the variability and reproducibility issues inherent in physical array manufacturing and experimental procedures
Solution Approach 2:
The patent transforms the analysis from physical parameters (signal intensity, binding affinity measurements) to computational parameters (binding predictions, interaction scores). This parameter transformation enables standardized, reproducible results that are not affected by manufacturing variability or experimental conditions, while reducing overall system complexity through automation
3Measurement precision
If comprehensive binding characterization is performed on all molecules, then complete binding properties are obtained, but the process becomes costly and time-consuming
Solution Approach 1:
The patent uses a computational copy of the peptide array to perform comprehensive binding characterization. The in silico array can simultaneously evaluate all peptides against all antibodies in the dataset, providing complete binding properties without the time-consuming sequential experimentation required for physical arrays
Solution Approach 2:
The computational system operates continuously without interruption, processing binding data and generating predictions simultaneously across all peptides and antibodies. This continuous computational action eliminates the sequential, time-consuming nature of experimental assays, achieving comprehensive characterization in a fraction of the time

AI summary
Systems, devices and methods for predicting binding on an array such as a peptide array. Certain methods utilize a peptide array having a plurality of peptides with one or more defined parameters and contacting the peptide array with a training sample containing one or more molecules of interest. Interactions between the plurality of peptides and the one or more molecules of interest are processed according to a data fitting model, which model is then is applied to interactions between the plurality of peptides and a test sample to predict binding associated with the one or more molecules of interest.
