Modular Protein Connector for Rapid Marker Library Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for generating large libraries of biological structures, such as markers, are time-consuming and require excessive reagents due to the need for cyclical staining, imaging, and data processing, especially in spatial biology applications requiring numerous markers.
Innovation Solution
A connector comprising a protein backbone with reactive and affinity interactors that allow for efficient assembly and cleavage, enabling rapid production of markers and capture constructs using bioconjugate formation and enzyme-cleavable sites.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If cyclical staining, imaging, and blanking processes are used to generate large libraries of markers, then the number of markers can be increased, but the time required and reagent consumption increase significantly
Solution Approach 1:
The connector is divided into separate functional modules (reactive interactor, affinity interactor, cleavage site) that can be independently synthesized and then rapidly assembled. This segmentation allows parallel production of different marker variants, dramatically reducing the time required to generate large libraries compared to sequential cyclical methods.
Solution Approach 2:
The connector serves as an intermediary building block that pre-integrates the reactive interactor and affinity interactor. This intermediate structure can be rapidly produced and stored, then quickly combined with different targets to generate diverse markers without repeating the full staining and imaging cycle for each variant.
2Quantity of substance
If cyclical staining, imaging, and blanking processes are used to generate large libraries of markers, then the number of markers can be increased, but reagent consumption increases significantly
Solution Approach 1:
By segmenting the marker into reusable connector components and variable target-specific components, reagents can be synthesized independently and in parallel. The connector portion with its reactive and affinity interactors can be produced once and reused across multiple marker variants, reducing overall reagent consumption compared to generating complete markers through repeated cyclical processes.
Solution Approach 2:
The modular connector design allows for recovery and reuse of the core connector structure across different marker applications. While the target-specific portions may be discarded after use, the valuable connector component with integrated interactors can be recovered and repurposed for generating additional marker variants, reducing net reagent consumption.
3Ease of manufacture
If traditional marker generation methods are used, then markers can be produced, but the process is time-consuming and inefficient
Solution Approach 1:
The connector is designed with pre-integrated reactive and affinity interactors that are synthesized and validated in advance. This preliminary preparation of the core structure allows for rapid assembly with different target components when needed, dramatically increasing production speed compared to traditional methods where the complete marker must be generated and validated from scratch each time.
Solution Approach 2:
The connector's modular design with built-in reactive and affinity interactors allows it to self-assemble with target components through spontaneous biochemical reactions (covalent bonding and affinity binding). This self-service capability eliminates the need for complex, time-consuming assembly procedures and validation steps for each new marker variant, improving both ease of manufacture and productivity.

AI summary
A connector for generating a biological structure includes a protein backbone, a first reactive interactor arranged towards a first end of the protein backbone and configured to covalently bind to a second reactive interactor, and a first affinity interactor arranged towards a second end of the protein backbone and configured to bind to a second affinity interactor. The protein backbone includes a cleavage site between the first end and the second end of the protein backbone. One of the first reactive interactor and the first affinity interactor is configured to bind to a first affinity reagent including the second reactive interactor or the second affinity interactor. Another one of the first reactive interactor and the first affinity interactor is configured to bind to a label or a second affinity reagent comprising the second reactive interactor or the second affinity interactor.
