Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for identifying novel polypeptides with desired activities are time-consuming and costly, often requiring extensive screening of numerous variants, making them unsuitable for timely and cost-effective development of commercial products.
Innovation Solution
The development of compositions and methods involving pluralities of polypeptides, where each member reacts with substrates or ligands to produce products, with at least two variants related to a parent polypeptide reacting with differing levels of activity, allowing for accelerated identification of polypeptides with enhanced activities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If current screening methods are used to identify novel polypeptides, then comprehensive screening of variants can be performed, but the process becomes time-consuming and costly
Solution Approach 1:
The patent applies preliminary action by pre-selecting and grouping polypeptide variants into pluralities based on their structural and functional characteristics before screening. This pre-organization allows the screening process to focus on specific groups with higher probability of containing desired variants, thereby reducing overall screening time while maintaining identification accuracy.
Solution Approach 2:
The patent segments the large set of polypeptide variants into multiple smaller pluralities or groups based on shared characteristics such as sequence homology, structural features, or predicted function. This segmentation allows parallel screening of multiple groups simultaneously, significantly reducing the total time required to identify novel polypeptides while maintaining comprehensive coverage.
2Reliability
If extensive screening of numerous polypeptide variants is performed, then novel polypeptides with desired activities can be identified, but the cost increases significantly
Solution Approach 1:
The patent changes parameters by selecting and grouping variants based on specific structural and functional parameters that are predictive of desired activity. By focusing screening efforts on variants that meet predetermined parameter criteria (such as sequence identity thresholds, structural motifs, or computational predictions), the method reduces the number of variants requiring extensive experimental screening, thereby lowering costs while maintaining identification reliability.
Solution Approach 2:
The patent creates pluralities of polypeptide variants that can serve multiple functions: they can be screened for various desired activities, used as templates for further variant generation, and applied in different screening contexts. This multi-functionality reduces the need for separate screening campaigns for different purposes, thereby reducing overall screening costs while maintaining comprehensive identification capability.
3Reliability
If more polypeptide variants are screened to ensure finding desired activities, then identification reliability improves, but the complexity of the screening process increases
Solution Approach 1:
The patent segments the screening process into distinct stages corresponding to different pluralities of variants. Each plurality is screened for specific characteristics, and results from one stage inform the selection and design of the next stage. This segmented approach breaks down the complex overall process into manageable, systematic steps, reducing perceived complexity while maintaining comprehensive screening coverage for reliable identification.
4Measurement precision
If traditional screening approaches are used, then thorough evaluation of variants can be conducted, but the productivity of polypeptide discovery decreases
Solution Approach 1:
The patent applies preliminary action by pre-characterizing and grouping variants into pluralities based on predicted activity profiles before conducting detailed activity measurements. This preliminary classification allows the subsequent precision evaluation to focus on the most promising variants within each plurality, maintaining measurement precision while accelerating the overall discovery rate by avoiding exhaustive screening of all variants.
Solution Approach 2:
The patent changes the approach by using computational predictions and structural parameters to prioritize which variants require detailed activity evaluation. By adjusting the selection parameters to focus on variants with highest predicted value, the method maintains precise activity measurement where needed while reducing the overall number of measurements required, thereby increasing productivity without sacrificing evaluation precision.
