Volatile Buffer Method for Biomolecule Localization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for localizing sulfhydryl group containing biomolecules to cell membranes in biological laboratories require equipment and expertise not typically available, limiting the use of bespoke KODE™ Constructs, which often necessitate purification steps like chromatography that result in losses and are undesirable.
Innovation Solution
A method involving mixing a molar excess of sulfhydryl group containing biomolecules with lipid conjugated maleimide in a volatile reaction buffer, incubating, drying to remove the buffer, and contacting the reaction product with the surface, bypassing the need for purification steps like chromatography, and a kit providing the necessary components for this method.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional purification methods (chromatography) are used to localize sulfhydryl group containing biomolecules to cell membranes, then the localization can be achieved, but material losses occur and the process becomes complex
Solution Approach 1:
The patent extracts and removes the purification step entirely from the process by using a volatile reaction buffer that can be easily evaporated, eliminating the need for chromatography and associated material losses
Solution Approach 2:
The patent changes the physical state of the reaction buffer from non-volatile to volatile, enabling simple evaporation-based removal without requiring complex purification equipment or procedures
2Reliability
If conventional purification methods (chromatography) are used to localize sulfhydryl group containing biomolecules to cell membranes, then the localization can be achieved, but the process complexity increases
Solution Approach 1:
The patent removes the chromatography step and associated equipment requirements from the process, simplifying the overall system to only essential components
Solution Approach 2:
The patent employs a volatile reaction buffer that can be easily discarded through evaporation, replacing expensive and complex chromatography equipment with a simple, disposable-like consumable
3Adaptability or versatility
If bespoke KODE™ Constructs are used, then customization capability is improved, but the requirement for specialized equipment and expertise increases
Solution Approach 1:
The patent changes the reaction buffer from non-volatile to volatile, enabling bespoke construct preparation using only standard laboratory equipment without requiring specialized chromatography systems
Solution Approach 2:
The volatile reaction buffer system allows the construct to be prepared and purified through simple evaporation, making the process self-contained and not requiring external specialized equipment or expertise

AI summary
Method of localizing a sulfhydryl (—SH) group containing biomolecule to the surface of a cell membrane by mixing in a volatile reaction buffer a molar excess of the sulfhydryl (—SH) group containing biomolecule with a lipid conjugated maleimide of the structure F-S-L as defined in the specification to provide a reaction mix, incubating the reaction mix for a time and at a temperature sufficient to allow all the lipid conjugated maleimide to have reacted with the sulfhydryl (—SH) group, and freeze-drying the reaction mix to remove the volatile reaction buffer and provide a reaction product. An aqueous solution of the reaction product is contacted with the cell membrane.
