Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for absolute nucleic acid quantification, particularly in DNA methylation analysis, face challenges in standardization due to a lack of consensus on suitable controls, leading to variability in results and precision.
Innovation Solution
The use of a combination of four genes, SYT10, EPHA3, PLEKHF1, and KBTBD4, as control genes for absolute DNA quantification, which outperforms traditional single-gene controls like ACTB and C-LESS, enabling improved precision and standardization in digital PCR-based methylation analyses.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional single-gene controls (ACTB, C-LESS) are used for absolute DNA quantification, then the method is simple and widely applicable, but the precision and standardization of results are poor due to variability
Solution Approach 1:
The patent combines four individual control genes (SYT10, EPHA3, PLEKHF1, KBTBD4) into a unified control panel for absolute DNA quantification. This merging of multiple control genes resolves the technical contradiction by providing improved measurement precision through multi-gene normalization while managing the complexity through a standardized panel design that can be implemented using existing PCR technology.
Solution Approach 2:
The patent creates a composite control system by integrating multiple control genes with different functional properties. Each gene in the panel (SYT10, EPHA3, PLEKHF1, KBTBD4) contributes different normalization capabilities, and their combination creates a more robust control system that corrects for various sources of variability including template amount and chromosomal aberrations, thereby improving measurement precision without requiring fundamentally new technology.
2Reliability
If a four-gene control panel (SYT10, EPHA3, PLEKHF1, KBTBD4) is used for absolute DNA quantification, then the precision and standardization are improved, but the complexity of the control system increases
Solution Approach 1:
The patent merges four control genes into a single integrated control panel that functions as a unified system for normalization. This approach improves reliability by combining the normalization capabilities of multiple genes, while the panel is designed to be implemented as a standardized protocol using conventional PCR equipment, thus managing the complexity through standardization rather than requiring complex new instrumentation.
Solution Approach 2:
The four-gene control panel is designed to be universally applicable across different PCR-based quantification methods and sample types. The control genes serve multiple functions including normalization for template amount, correction for chromosomal aberrations, and standardization across different laboratories and platforms. This multi-functionality improves reliability while the universal design allows implementation using existing technology, managing complexity through versatility.
3Measurement precision
If traditional control methods are used, then the protocol is simple and widely applicable, but variability in template amount and chromosomal aberrations cannot be corrected
Solution Approach 1:
The patent combines multiple control genes into a single panel that simultaneously corrects for template amount variability and chromosomal aberrations. This merging provides improved measurement precision for methylation pattern analysis while the panel is designed to be implemented using standard PCR protocols, maintaining ease of operation through compatibility with existing workflows rather than requiring fundamentally new procedures.
Solution Approach 2:
The composite control panel integrates four genes with different normalization properties, creating a robust system that corrects for multiple sources of variability including template amount and chromosomal aberrations. This composite approach improves measurement precision while each gene in the panel can be amplified using conventional PCR primers and protocols, maintaining ease of implementation through compatibility with existing technology.
