Solution Overview
Problem
There is a need for new and enhanced materials and methods in staining proteins in polyacrylamide gels, as existing techniques like Coomassie Brilliant Blue staining have limitations in sensitivity and compatibility with mass spectrometry.
Innovation Solution
The use of Meldrum's acid Activated Furan (MAF) as a staining agent, which is dissolved in a suitable solvent and applied to polyacrylamide gels to visualize protein fragments separated by gel electrophoresis, allowing for discernible staining by human vision and conventional analysis techniques.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If Coomassie Brilliant Blue staining is used for protein visualization, then cost is reduced and ease of operation is improved, but sensitivity and mass spectrometry compatibility deteriorate
Solution Approach 1:
The patent modifies the chemical structure of furan by activating it with Meldrum's acid to create MAF, changing its staining parameters to achieve both high sensitivity (detecting down to 50 ng protein) and mass spectrometry compatibility while maintaining ease of use
Solution Approach 2:
The staining agent is formed as a composite of furan and Meldrum's acid (MAF), combining the properties of both components to achieve superior sensitivity and mass spectrometry compatibility compared to conventional stains like Coomassie Brilliant Blue
2Reliability
If conventional staining methods are used, then mass spectrometry compatibility is improved, but staining intensity and visibility deteriorate
Solution Approach 1:
The patent optimizes the chemical parameters of the staining agent by synthesizing MAF with specific structural characteristics that enable both intense staining (comparable to Coomassie Brilliant Blue) and compatibility with mass spectrometry analysis
3Measurement precision
If new staining materials are developed to enhance sensitivity, then measurement precision is improved, but device complexity and manufacturing difficulty increase
Solution Approach 1:
The patent achieves high sensitivity (50 ng detection limit) through chemical parameter optimization of MAF rather than through complex device modifications, maintaining simplicity in the staining procedure while dramatically improving measurement precision
Solution Approach 2:
The staining agent MAF is designed as a simple, inexpensive chemical compound that can be readily synthesized and discarded, avoiding the need for expensive, complex, or difficult-to-manufacture staining systems

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
MAF staining provides intense and visible protein bands comparable to Coomassie Brilliant Blue, with sensitivity up to 50 ng protein and compatibility with mass spectrometry, enabling effective protein visualization and analysis.
Implementation Method 1
treating the polyacrylamide gel with Meldrum's acid Activated Furan (MAF) dissolved in a suitable solvent. The method is characterized in that the MAF stains the molecular fragments in a manner to be discernible by human vision and by conventional analysis techniques
Implementation Method 2
resolving the protein sample by applying an electrical potential across the gel for a period of time, separating molecular fragments of the protein into the fragment pattern in the gel
