Conventional methods for eluting analytes from immunoaffinity columns require harsh elution solutions, leading to compatibility issues with downstream analysis, which often necessitate dilution and buffer exchange processes that degrade sensitivity and precision.
Innovation Solution
The method employs thermal energy to dissociate analytes from the immunoaffinity column, eliminating the need for harsh elution solutions and allowing the eluate to be directly compatible with downstream processes without modification.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If harsh elution solutions are used to dissociate analyte from immunoaffinity column, then elution efficiency is improved, but compatibility with downstream analysis deteriorates
Solution Approach 1:
The patent changes the elution mechanism from chemical (harsh elution solutions) to physical (thermal energy). By heating the immunoaffinity column to temperatures between 65-95°C, the analyte is dissociated from the stationary phase through thermal energy rather than chemical reactions, producing an eluate that is compatible with downstream analysis without requiring harsh chemicals
Solution Approach 2:
The patent replaces the chemical elution system with a thermal energy system. Instead of using strong acidic or basic buffers, high salt solutions, or organic solvents, the invention uses heat (thermal energy) to disrupt the binding between the analyte and antibodies on the column, eliminating the need for chemical elution solutions
2Adaptability or versatility
If dilution is performed to condition eluate, then compatibility with downstream analysis is improved, but sensitivity deteriorates
Solution Approach 1:
The patent extracts and eliminates the problematic element (harsh elution solutions) from the process. By using thermal energy for elution instead of chemical solutions, the invention removes the need for subsequent dilution and buffer exchange steps, thereby preserving the sensitivity of the analyte while achieving compatibility with downstream analysis
3Adaptability or versatility
If buffer exchange processes are performed to condition eluate, then compatibility with downstream analysis is improved, but precision deteriorates due to introduction of impurities
Solution Approach 1:
The patent removes the buffer exchange step from the workflow by using thermal elution. Since heating the column to 65-95°C dissociates the analyte without requiring chemical buffer modifications, the eluate can be directly used for downstream analysis without introducing impurities or matrix effects that would compromise precision
4Adaptability or versatility
If multiple conditioning steps are added to eluate, then compatibility with downstream analysis is improved, but processing time increases
Solution Approach 1:
The patent extracts and eliminates the conditioning steps (dilution and buffer exchange) from the workflow. By using thermal energy to dissociate the analyte from the immunoaffinity column, the invention produces an eluate that is ready for direct downstream analysis, eliminating time-consuming processing steps while maintaining compatibility
