Arrayed Target Proteins for High-Throughput Affinity Screening
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current affinity selection processes for recombinant reagents face challenges due to the high resource requirements for generating target proteins, which are often labile and prone to degradation, leading to low throughput and inefficiency.
Innovation Solution
The use of arrayed targets, such as freshly translated proteins synthesized in situ using NAPPA technology, allows for simultaneous screening of multiple targets, reducing the need for large quantities of stable target proteins and enhancing the efficiency of affinity selection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional affinity selection processes are used with individual target proteins, then the selection process can be performed, but the throughput is low and significant amounts of target protein are required
Solution Approach 1:
The patent divides the target protein selection process into multiple separate array spots, each containing a different target protein. This segmentation allows simultaneous screening against multiple targets in a single experiment, dramatically increasing throughput while reducing the amount of each individual target protein needed.
Solution Approach 2:
The patent transitions from linear, sequential target testing to a two-dimensional array format where multiple targets are spatially organized on a solid support. This dimensional change enables parallel processing of multiple targets simultaneously, resolving the contradiction between throughput and resource consumption.
2Productivity
If labile protein targets are used in affinity selection, then the targets can be utilized for selection, but the targets are prone to degradation and denaturation causing selection failures
Solution Approach 1:
The patent prepares and arrays target proteins on solid supports in advance, under controlled conditions, before the affinity selection process begins. This preliminary preparation allows labile proteins to be stabilized in a controlled environment and protects them from degradation during storage and handling, ensuring reliability when used in selection experiments.
Solution Approach 2:
The patent creates multiple copies of target proteins and arrays them on solid supports. This allows the use of freshly synthesized, stable target copies for each selection experiment rather than repeatedly using the same labile protein samples, thereby maintaining reliability across multiple experimental rounds.
3Reliability
If high-quality target proteins are generated for affinity selection, then the quality of selection can be maintained, but significant resources are devoted to generating these targets
Solution Approach 1:
The patent creates a universal target array platform that can be used for screening against multiple different target proteins simultaneously. This multi-functional array system allows a single experimental setup to serve multiple selection purposes, reducing the need to generate and maintain separate high-quality target preparations for each individual target, thereby conserving resources while maintaining selection quality.
