Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing technologies lack the ability to comprehensively characterize and quantify proteoforms at high throughput and high sensitivity, which are crucial for understanding the role of proteins in diseases like Parkinson's, as they provide inadequate diagnostic or prognostic precision.
Innovation Solution
Methods and systems for analyzing proteoforms involve individually interrogating proteins using affinity reagents specific for different proteoform characteristics, allowing for the characterization and quantification of proteoforms, particularly of alpha-synuclein protein, through array-based techniques and fluidic systems.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If high throughput detection technologies are used to analyze proteoforms, then productivity is improved, but measurement precision deteriorates
Solution Approach 1:
The patent segments the proteoform analysis process into multiple specialized detection channels, each optimized for specific types of modifications (phosphorylation, glycosylation, acetylation, etc.). This allows high throughput analysis while maintaining precision by dedicating specific detection mechanisms to specific modification types rather than using a single general-purpose detection method.
Solution Approach 2:
The patent introduces intermediary capture reagents (antibodies, aptamers, or other binding molecules) that specifically recognize and capture modified proteoforms before detection. These intermediaries enable highly specific enrichment and detection of target proteoforms, maintaining measurement precision while allowing automated high-throughput processing of multiple samples.
2Loss of information
If comprehensive proteoform characterization is performed, then information completeness is improved, but device complexity worsens
Solution Approach 1:
The system is segmented into modular detection units, each designed to detect specific types of proteoform modifications. This modularity allows comprehensive characterization through combination of simple, specialized detection modules rather than one complex monolithic system, reducing overall device complexity while maintaining information completeness.
Solution Approach 2:
The patent employs universal capture reagents and detection platforms that can be applied across multiple proteoform types and modification classes. This multi-functionality allows a single system to comprehensively characterize diverse proteoforms without requiring separate specialized equipment for each modification type, thereby managing device complexity.
3Measurement precision
If sensitive detection methods are used for proteoforms, then measurement precision is improved, but reliability worsens
Solution Approach 1:
The patent incorporates built-in control mechanisms and reference standards that are processed alongside test samples. These pre-established references provide baseline data and control points that cushion against variability in sensitive detection, ensuring reproducible results even when detecting low-abundance proteoforms with high sensitivity methods.
Solution Approach 2:
The system implements feedback mechanisms where detection results are continuously monitored and compared against expected ranges and control samples. This feedback allows real-time adjustment of detection parameters and identification of outliers, maintaining both high sensitivity for rare proteoforms and high reliability through automated quality control.
